profile: upgrade the "profile" context manager to a full class

So far we have been able to use a simple decorator for this. However using the
current context manager makes the scope of the profiling in dispatch
constrainted and the time frame to decide to enable profiling quite limited
(using "maybeprofile")

This is the first step toward the ability to enable the profiling from within
the profiling scope. eg::

  with maybeprofiling(ui) as profiler:
      ...
      bar.foo():
      ...
      if options['profile']:
          profiler.start()
      ...
      fooz()
      ...

My target usecase is adding support for  "--profile" to alias definitions with
effect.  These are to be used with "profiling.output=blackbox" to gather data
about operation that get slow from time to time (eg: pull being minutes instead
of seconds from time to time).

Of course, in such case, the scope of the profiling would be smaller since
profiler would be started after running extensions 'reposetup' (and other
potentially costly logic), but these are not relevant for my target usecase
(multiple second commits, multiple tens of seconds pull).

Currently adding '--profile' to a command through alias requires to re-spin a
Mercurial binary (using "!$HG" in alias), which as a significant performance
impact, especially in context where startup performance is being worked on...

An alternative approach would be to stop using the context manager in dispatch
and move back to a try/finally setup.

  $ hg init ignorerepo
  $ cd ignorerepo

debugignore with no hgignore should be deterministic:
  $ hg debugignore
  <nevermatcher>

Issue562: .hgignore requires newline at end:

  $ touch foo
  $ touch bar
  $ touch baz
  $ cat > makeignore.py <<EOF
  > f = open(".hgignore", "w")
  > f.write("ignore\n")
  > f.write("foo\n")
  > # No EOL here
  > f.write("bar")
  > f.close()
  > EOF

  $ python makeignore.py

Should display baz only:

  $ hg status
  ? baz

  $ rm foo bar baz .hgignore makeignore.py

  $ touch a.o
  $ touch a.c
  $ touch syntax
  $ mkdir dir
  $ touch dir/a.o
  $ touch dir/b.o
  $ touch dir/c.o

  $ hg add dir/a.o
  $ hg commit -m 0
  $ hg add dir/b.o

  $ hg status
  A dir/b.o
  ? a.c
  ? a.o
  ? dir/c.o
  ? syntax

  $ echo "*.o" > .hgignore
  $ hg status
  abort: $TESTTMP/ignorerepo/.hgignore: invalid pattern (relre): *.o (glob)
  [255]

  $ echo ".*\.o" > .hgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? syntax

Ensure that comments work:

  $ touch 'foo#bar' 'quux#'
#if no-windows
  $ touch 'baz\#wat'
#endif
  $ cat <<'EOF' >> .hgignore
  > # full-line comment
  >   # whitespace-only comment line
  > syntax# pattern, no whitespace, then comment
  > a.c  # pattern, then whitespace, then comment
  > baz\\# # escaped comment character
  > foo\#b # escaped comment character
  > quux\## escaped comment character at end of name
  > EOF
  $ hg status
  A dir/b.o
  ? .hgignore
  $ rm 'foo#bar' 'quux#'
#if no-windows
  $ rm 'baz\#wat'
#endif

Check it does not ignore the current directory '.':

  $ echo "^\." > .hgignore
  $ hg status
  A dir/b.o
  ? a.c
  ? a.o
  ? dir/c.o
  ? syntax

Test that patterns from ui.ignore options are read:

  $ echo > .hgignore
  $ cat >> $HGRCPATH << EOF
  > [ui]
  > ignore.other = $TESTTMP/ignorerepo/.hg/testhgignore
  > EOF
  $ echo "glob:**.o" > .hg/testhgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? syntax

empty out testhgignore
  $ echo > .hg/testhgignore

Test relative ignore path (issue4473):

  $ cat >> $HGRCPATH << EOF
  > [ui]
  > ignore.relative = .hg/testhgignorerel
  > EOF
  $ echo "glob:*.o" > .hg/testhgignorerel
  $ cd dir
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? syntax

  $ cd ..
  $ echo > .hg/testhgignorerel
  $ echo "syntax: glob" > .hgignore
  $ echo "re:.*\.o" >> .hgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? syntax

  $ echo "syntax: invalid" > .hgignore
  $ hg status
  $TESTTMP/ignorerepo/.hgignore: ignoring invalid syntax 'invalid' (glob)
  A dir/b.o
  ? .hgignore
  ? a.c
  ? a.o
  ? dir/c.o
  ? syntax

  $ echo "syntax: glob" > .hgignore
  $ echo "*.o" >> .hgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? syntax

  $ echo "relglob:syntax*" > .hgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? a.o
  ? dir/c.o

  $ echo "relglob:*" > .hgignore
  $ hg status
  A dir/b.o

  $ cd dir
  $ hg status .
  A b.o

  $ hg debugignore
  <includematcher includes='(?:(?:|.*/)[^/]*(?:/|$))'>

  $ hg debugignore b.o
  b.o is ignored
  (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 1: '*') (glob)

  $ cd ..

Check patterns that match only the directory

  $ echo "^dir\$" > .hgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? a.o
  ? syntax

Check recursive glob pattern matches no directories (dir/**/c.o matches dir/c.o)

  $ echo "syntax: glob" > .hgignore
  $ echo "dir/**/c.o" >> .hgignore
  $ touch dir/c.o
  $ mkdir dir/subdir
  $ touch dir/subdir/c.o
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? a.o
  ? syntax
  $ hg debugignore a.c
  a.c is not ignored
  $ hg debugignore dir/c.o
  dir/c.o is ignored
  (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 2: 'dir/**/c.o') (glob)

Check using 'include:' in ignore file

  $ hg purge --all --config extensions.purge=
  $ touch foo.included

  $ echo ".*.included" > otherignore
  $ hg status -I "include:otherignore"
  ? foo.included

  $ echo "include:otherignore" >> .hgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? otherignore

Check recursive uses of 'include:'

  $ echo "include:nested/ignore" >> otherignore
  $ mkdir nested
  $ echo "glob:*ignore" > nested/ignore
  $ hg status
  A dir/b.o

  $ cp otherignore goodignore
  $ echo "include:badignore" >> otherignore
  $ hg status
  skipping unreadable pattern file 'badignore': No such file or directory
  A dir/b.o

  $ mv goodignore otherignore

Check using 'include:' while in a non-root directory

  $ cd ..
  $ hg -R ignorerepo status
  A dir/b.o
  $ cd ignorerepo

Check including subincludes

  $ hg revert -q --all
  $ hg purge --all --config extensions.purge=
  $ echo ".hgignore" > .hgignore
  $ mkdir dir1 dir2
  $ touch dir1/file1 dir1/file2 dir2/file1 dir2/file2
  $ echo "subinclude:dir2/.hgignore" >> .hgignore
  $ echo "glob:file*2" > dir2/.hgignore
  $ hg status
  ? dir1/file1
  ? dir1/file2
  ? dir2/file1

Check including subincludes with regexs

  $ echo "subinclude:dir1/.hgignore" >> .hgignore
  $ echo "regexp:f.le1" > dir1/.hgignore

  $ hg status
  ? dir1/file2
  ? dir2/file1

Check multiple levels of sub-ignores

  $ mkdir dir1/subdir
  $ touch dir1/subdir/subfile1 dir1/subdir/subfile3 dir1/subdir/subfile4
  $ echo "subinclude:subdir/.hgignore" >> dir1/.hgignore
  $ echo "glob:subfil*3" >> dir1/subdir/.hgignore

  $ hg status
  ? dir1/file2
  ? dir1/subdir/subfile4
  ? dir2/file1

Check include subignore at the same level

  $ mv dir1/subdir/.hgignore dir1/.hgignoretwo
  $ echo "regexp:f.le1" > dir1/.hgignore
  $ echo "subinclude:.hgignoretwo" >> dir1/.hgignore
  $ echo "glob:file*2" > dir1/.hgignoretwo

  $ hg status | grep file2
  [1]
  $ hg debugignore dir1/file2
  dir1/file2 is ignored
  (ignore rule in dir2/.hgignore, line 1: 'file*2')

#if windows

Windows paths are accepted on input

  $ rm dir1/.hgignore
  $ echo "dir1/file*" >> .hgignore
  $ hg debugignore "dir1\file2"
  dir1\file2 is ignored
  (ignore rule in $TESTTMP\ignorerepo\.hgignore, line 4: 'dir1/file*')
  $ hg up -qC .
