obsolete: use parsers.fm1readmarker if it exists for a ~38% perf win

This moves perfloadmarkers on my linux workstation (63494 markers from
mpm, crew, and myself) performance from
! wall 0.357657 comb 0.360000 user 0.350000 sys 0.010000 (best of 28)
to
! wall 0.222345 comb 0.220000 user 0.210000 sys 0.010000 (best of 41)
which is a pretty good improvement.

On my BSD machine, which is ancient and slow, before:
! wall 3.584964 comb 3.578125 user 3.539062 sys 0.039062 (best of 3)
after:
! wall 2.267974 comb 2.265625 user 2.195312 sys 0.070312 (best of 5)


I feel like we could do better by moving the whole generator function
into C, but I didn't want to tackle that right away.

  $ hg init

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/.hgignore: invalid pattern (relre): *.o (glob)
  [255]

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

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/.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/.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
  (?:(?:|.*/)[^/]*(?:/|$))

  $ 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
