dirstate: ignore symlinks when fs cannot handle them (issue1888)

When the filesystem cannot handle the executable bit, we currently
ignore it completely when looking for modified files. Similarly, it is
impossible to set or clear the bit when the filesystem ignores it.

This patch makes Mercurial treat symbolic links the same way.

Symlinks are a little different since they manifest themselves as
small files containing a filename (the symlink target). On Windows,
these files show up as regular files, and on Linux and Mac they show
up as real symlinks.

Issue1888 presents a case where the symlink files are better ignored
from the Windows side. A Linux client creates symlinks in a working
copy which is shared over a network between Linux and Windows clients.

The Samba server is helpful and defererences the symlink when the
Windows client looks at it. This means that Mercurial on the Windows
side sees file content instead of a file name in the symlink, and
hence flags the link as modified. Ignoring the change would be much
more helpful, similarly to how Mercurial does not report any changes
when executable bits are ignored in a checkout on Windows.

An initial checkout of a symbolic link on a file system that cannot
handle symbolic links will still result in a regular file containing
the target file name as its content. Sharing such a checkout with a
Linux client will not turn the file into a symlink automatically, but
'hg revert' can fix that. After the revert, the Windows client will
see the correct file content (provided by the Samba server when it
follows the link on the Linux side) and otherwise ignore the change.

Running 'hg perfstatus' 10 times gives these results:

  Before:          After:
  min: 0.544703    min: 0.546549
  med: 0.547592    med: 0.548881
  avg: 0.549146    avg: 0.548549
  max: 0.564112    max: 0.551504

The median time is increased about 0.24%.

    Another definition. The final line in the definition
    determines the indentation, so this will be indented
    with four spaces.

literals formatted to fit within 60 characters:
----------------------------------------------------------------------
The fully minimized form is the most convenient form:

  Hello
    literal
      world

In the partially minimized form a paragraph simply ends with
space-double-colon.

  ////////////////////////////////////////
  long un-wrapped line in a literal block
  \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

  This literal block is started with '::',
    the so-called expanded form. The paragraph
      with '::' disappears in the final output.

lists formatted to fit within 60 characters:
----------------------------------------------------------------------
- This is the first list item.

  Second paragraph in the first list item.

- List items need not be separated by a blank line.
- And will be rendered without one in any case.

We can have indented lists:

  - This is an indented list item
  - Another indented list item:

      - A literal block in the middle
            of an indented list.

      (The above is not a list item since we are in the literal block.)

  Literal block with no indentation (apart from
  the two spaces added to all literal blocks).

1. This is an enumerated list (first item).
2. Continuing with the second item.
(1) foo
(2) bar
1) Another
2) List

Line blocks are also a form of list:

This is the first line. The line continues here.
This is the second line.

options formatted to fit within 60 characters:
----------------------------------------------------------------------
There is support for simple option lists, but only with long
options:

--all      Output all.
--both     Output both (this description is quite long).
--long     Output all day long.
--par      This option has two paragraphs in its
           description. This is the first.

           This is the second.  Blank lines may be omitted
           between options (as above) or left in (as here).

The next paragraph looks like an option list, but lacks the
two-space marker after the option. It is treated as a normal
paragraph:

--foo bar baz
