parsers: fail fast if Python has wrong minor version (issue4110)

This change causes an informative ImportError to be raised when importing
the parsers extension module if the minor version of the currently-running
Python interpreter doesn't match that of the Python used when compiling
the extension module.

This change also exposes a parsers.versionerrortext constant in the
C implementation of the module.  Its presence can be used to determine
whether this behavior is present in a version of the module.  The value
of the constant is the leading text of the ImportError raised and is set
to "Python minor version mismatch".

Here is an example of what the new error looks like:

  Traceback (most recent call last):
    File "test.py", line 1, in <module>
      import mercurial.parsers
  ImportError: Python minor version mismatch: The Mercurial extension
  modules were compiled with Python 2.7.6, but Mercurial is currently using
  Python with sys.hexversion=33883888: Python 2.5.6
  (r256:88840, Nov 18 2012, 05:37:10)
  [GCC 4.2.1 Compatible Apple Clang 4.1 ((tags/Apple/clang-421.11.66))]
   at: /opt/local/Library/Frameworks/Python.framework/Versions/2.5/Resources/
    Python.app/Contents/MacOS/Python

The reason for raising an error in this scenario is that Python's C API
is known not to be compatible from minor version to minor version, even
if sys.api_version is the same.  See for example this Python bug report
about incompatibilities between 2.5 and 2.6+:

  http://bugs.python.org/issue8118

These incompatibilities can cause Mercurial to break in mysterious,
unforeseen ways.  For example, when Mercurial compiled with Python 2.7 was
run with 2.5, the following crash occurred when running "hg status":

  http://bz.selenic.com/show_bug.cgi?id=4110

After this crash was fixed, running with Python 2.5 no longer crashes, but
the following puzzling behavior still occurs:

    $ hg status
      ...
      File ".../mercurial/changelog.py", line 123, in __init__
        revlog.revlog.__init__(self, opener, "00changelog.i")
      File ".../mercurial/revlog.py", line 251, in __init__
        d = self._io.parseindex(i, self._inline)
      File ".../mercurial/revlog.py", line 158, in parseindex
        index, cache = parsers.parse_index2(data, inline)
    TypeError: data is not a string

which can be reproduced more simply with:

    import mercurial.parsers as parsers
    parsers.parse_index2("", True)

Both the crash and the TypeError occurred because the Python C API's
PyString_Check() returns the wrong value when the C header files from
Python 2.7 are run with Python 2.5.  This is an example of an
incompatibility of the sort mentioned in the Python bug report above.

Failing fast with an informative error message results in a better user
experience in cases like the above.  The information in the ImportError
also simplifies troubleshooting for those on Mercurial mailing lists, the
bug tracker, etc.

This patch only adds the version check to parsers.c, which is sufficient
to affect command-line commands like "hg status" and "hg summary".
An idea for a future improvement is to move the version-checking C code
to a more central location, and have it run when importing all
Mercurial extension modules and not just parsers.c.

  Using Additional Features
  """""""""""""""""""""""""
  
      Mercurial has the ability to add new features through the use of
      extensions. Extensions may add new commands, add options to existing
      commands, change the default behavior of commands, or implement hooks.
  
      To enable the "foo" extension, either shipped with Mercurial or in the
      Python search path, create an entry for it in your configuration file,
      like this:
  
        [extensions]
        foo =
  
      You may also specify the full path to an extension:
  
        [extensions]
        myfeature = ~/.hgext/myfeature.py
  
      See "hg help config" for more information on configuration files.
  
      Extensions are not loaded by default for a variety of reasons: they can
      increase startup overhead; they may be meant for advanced usage only; they
      may provide potentially dangerous abilities (such as letting you destroy
      or modify history); they might not be ready for prime time; or they may
      alter some usual behaviors of stock Mercurial. It is thus up to the user
      to activate extensions as needed.
  
      To explicitly disable an extension enabled in a configuration file of
      broader scope, prepend its path with !:
  
        [extensions]
        # disabling extension bar residing in /path/to/extension/bar.py
        bar = !/path/to/extension/bar.py
        # ditto, but no path was supplied for extension baz
        baz = !
  
      enabled extensions:
  
       children      command to display child changesets (DEPRECATED)
       rebase        command to move sets of revisions to a different ancestor
  
      disabled extensions:

      Verify the integrity of the current repository.
  
      This will perform an extensive check of the repository's integrity,
      validating the hashes and checksums of each entry in the changelog,
      manifest, and tracked files, as well as the integrity of their crosslinks
      and indices.
  
      Please see http://mercurial.selenic.com/wiki/RepositoryCorruption for more
      information about recovery from corruption of the repository.
  
      Returns 0 on success, 1 if errors are encountered.
  
  use "hg -v help verify" to show the global options

  $ hg help diff
  hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...
  
  diff repository (or selected files)
  
      Show differences between revisions for the specified files.
  
      Differences between files are shown using the unified diff format.
  
      Note:
         diff may generate unexpected results for merges, as it will default to
         comparing against the working directory's first parent changeset if no
         revisions are specified.
  
      When two revision arguments are given, then changes are shown between
      those revisions. If only one revision is specified then that revision is
      compared to the working directory, and, when no revisions are specified,
      the working directory files are compared to its parent.
  
      Alternatively you can specify -c/--change with a revision to see the
      changes in that changeset relative to its first parent.
  
      Without the -a/--text option, diff will avoid generating diffs of files it
      detects as binary. With -a, diff will generate a diff anyway, probably
      with undesirable results.
  
      Use the -g/--git option to generate diffs in the git extended diff format.
      For more information, read "hg help diffs".
  
      Returns 0 on success.
  
  options:
  
   -r --rev REV [+]         revision
   -c --change REV          change made by revision
   -a --text                treat all files as text
   -g --git                 use git extended diff format
      --nodates             omit dates from diff headers
   -p --show-function       show which function each change is in
      --reverse             produce a diff that undoes the changes
   -w --ignore-all-space    ignore white space when comparing lines
   -b --ignore-space-change ignore changes in the amount of white space
   -B --ignore-blank-lines  ignore changes whose lines are all blank
   -U --unified NUM         number of lines of context to show
      --stat                output diffstat-style summary of changes
   -I --include PATTERN [+] include names matching the given patterns

  [+] marked option can be specified multiple times
  
  use "hg -v help diff" to show more complete help and the global options

  $ hg help status
  hg status [OPTION]... [FILE]...
  
  aliases: st
  
  show changed files in the working directory
  
      Show status of files in the repository. If names are given, only files
      that match are shown. Files that are clean or ignored or the source of a
      copy/move operation, are not listed unless -c/--clean, -i/--ignored,
      -C/--copies or -A/--all are given. Unless options described with "show
      only ..." are given, the options -mardu are used.
  
      Option -q/--quiet hides untracked (unknown and ignored) files unless
      explicitly requested with -u/--unknown or -i/--ignored.
  
      Note:
         status may appear to disagree with diff if permissions have changed or
         a merge has occurred. The standard diff format does not report
         permission changes and diff only reports changes relative to one merge
         parent.
  
      If one revision is given, it is used as the base revision. If two
      revisions are given, the differences between them are shown. The --change
      option can also be used as a shortcut to list the changed files of a
      revision from its first parent.
  
      The codes used to show the status of files are:
  
        M = modified
        A = added
        R = removed
        C = clean
        ! = missing (deleted by non-hg command, but still tracked)
        ? = not tracked
        I = ignored
          = origin of the previous file (with --copies)
  
      Returns 0 on success.
  
  options:
  
   -A --all                 show status of all files
   -m --modified            show only modified files
   -a --added               show only added files
   -r --removed             show only removed files
   -d --deleted             show only deleted (but tracked) files
   -c --clean               show only files without changes
   -u --unknown             show only unknown (not tracked) files
   -i --ignored             show only ignored files
   -n --no-status           hide status prefix
   -C --copies              show source of copied files
   -0 --print0              end filenames with NUL, for use with xargs
      --rev REV [+]         show difference from revision
      --change REV          list the changed files of a revision
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
   -S --subrepos            recurse into subrepositories

Test a help topic

  $ hg help revs
  Specifying Single Revisions
  """""""""""""""""""""""""""
  
      Mercurial supports several ways to specify individual revisions.
  
      A plain integer is treated as a revision number. Negative integers are
      treated as sequential offsets from the tip, with -1 denoting the tip, -2
      denoting the revision prior to the tip, and so forth.
  
      A 40-digit hexadecimal string is treated as a unique revision identifier.
  
      A hexadecimal string less than 40 characters long is treated as a unique
      revision identifier and is referred to as a short-form identifier. A
      short-form identifier is only valid if it is the prefix of exactly one
      full-length identifier.
  
      Any other string is treated as a bookmark, tag, or branch name. A bookmark
      is a movable pointer to a revision. A tag is a permanent name associated
      with a revision. A branch name denotes the tipmost open branch head of
      that branch - or if they are all closed, the tipmost closed head of the
      branch. Bookmark, tag, and branch names must not contain the ":"
      character.
  
      The reserved name "tip" always identifies the most recent revision.
  
      The reserved name "null" indicates the null revision. This is the revision
      of an empty repository, and the parent of revision 0.
  
      The reserved name "." indicates the working directory parent. If no
      working directory is checked out, it is equivalent to null. If an
      uncommitted merge is in progress, "." is the revision of the first parent.

Test templating help

  $ hg help templating | egrep '(desc|diffstat|firstline|nonempty)  '
      desc          String. The text of the changeset description.
      diffstat      String. Statistics of changes with the following format:
      firstline     Any text. Returns the first line of text.
      nonempty      Any text. Returns '(none)' if the string is empty.

  <h1>Specifying Single Revisions</h1>
  <p>
  Mercurial supports several ways to specify individual revisions.
  </p>
  <p>
  A plain integer is treated as a revision number. Negative integers are
  treated as sequential offsets from the tip, with -1 denoting the tip,
  -2 denoting the revision prior to the tip, and so forth.
  </p>
  <p>
  A 40-digit hexadecimal string is treated as a unique revision
  identifier.
  </p>
  <p>
  A hexadecimal string less than 40 characters long is treated as a
  unique revision identifier and is referred to as a short-form
  identifier. A short-form identifier is only valid if it is the prefix
  of exactly one full-length identifier.
  </p>
  <p>
  Any other string is treated as a bookmark, tag, or branch name. A
  bookmark is a movable pointer to a revision. A tag is a permanent name
  associated with a revision. A branch name denotes the tipmost open branch head
  of that branch - or if they are all closed, the tipmost closed head of the
  branch. Bookmark, tag, and branch names must not contain the &quot;:&quot; character.
  </p>
  <p>
  The reserved name &quot;tip&quot; always identifies the most recent revision.
  </p>
  <p>
  The reserved name &quot;null&quot; indicates the null revision. This is the
  revision of an empty repository, and the parent of revision 0.
  </p>
  <p>
  The reserved name &quot;.&quot; indicates the working directory parent. If no
  working directory is checked out, it is equivalent to null. If an
  uncommitted merge is in progress, &quot;.&quot; is the revision of the first
  parent.
