abort: added logic for of hg abort

This is part of `GSoC19` project `Implement abort and
continue commands`. This patch is part of the `abort plan`.

This adds the basic logic for `hg abort`. This command
aborts an multistep operation like graft, histedit, rebase,
merge and unshelve if they are in an unfinished state.

The first part of the logic is determining the unfinished
operation from the state detection API under `statemod`.
This API is extended to support `hg abort` by adding a method
to register the abort logic as a function (here `abortfunc`).

Once the unfinished operation is determined the registered
logic is used to abort the command. The benefit of this kind
of framework is that any new extension developed can support
`hg abort` by registering the command and logic under
statedetection API.

`hg abort` currently supports `--dry-run/-n` flag only.
It is used to dry run `hg abort`

Further patches sequentially add support for `graft`, `rebase`,
`unshelve`, `histedit` and `merge`.

  $ 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]

Ensure given files are relative to cwd

  $ echo "dir/.*\.o" > .hgignore
  $ hg status -i
  I dir/c.o

  $ hg debugignore dir/c.o dir/missing.o
  dir/c.o is ignored
  (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 1: 'dir/.*\.o') (glob)
  dir/missing.o is ignored
  (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 1: 'dir/.*\.o') (glob)
  $ cd dir
  $ hg debugignore c.o missing.o
  c.o is ignored
  (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 1: 'dir/.*\.o') (glob)
  missing.o is ignored
  (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 1: 'dir/.*\.o') (glob)

For icasefs, inexact matches also work, except for missing files

#if icasefs
  $ hg debugignore c.O missing.O
  c.o is ignored
  (ignore rule in $TESTTMP/ignorerepo/.hgignore, line 1: 'dir/.*\.o') (glob)
  missing.O is not ignored
#endif

  $ cd ..

  $ 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 that '^\.' does not ignore the root 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'
  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

"(fsmonitor !)" below assumes that fsmonitor is enabled with
"walk_on_invalidate = false" (default), which doesn't involve
re-walking whole repository at detection of .hgignore change.

  $ echo "^dir\$" > .hgignore
  $ hg status
  A dir/b.o
  ? .hgignore
  ? a.c
  ? a.o
  ? dir/c.o (fsmonitor !)
  ? 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 rooted globs

  $ hg purge --all --config extensions.purge=
  $ echo "syntax: rootglob" > .hgignore
  $ echo "a/*.ext" >> .hgignore
  $ for p in a b/a aa; do mkdir -p $p; touch $p/b.ext; done
  $ hg status -A 'set:**.ext'
  ? aa/b.ext
  ? b/a/b.ext
  I a/b.ext

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 nested/more
  $ echo "glob:*ignore" > nested/ignore
  $ echo "rootglob:a" >> nested/ignore
  $ touch a nested/a nested/more/a
  $ hg status
  A dir/b.o
  ? nested/a
  ? nested/more/a
  $ rm a nested/a nested/more/a

  $ cp otherignore goodignore
  $ echo "include:badignore" >> otherignore
  $ hg status
  skipping unreadable pattern file 'badignore': $ENOENT$
  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 other patterns

  $ echo "subinclude:dir1/.hgignore" >> .hgignore

  $ mkdir dir1/subdir
  $ touch dir1/subdir/file1
  $ echo "rootglob:f?le1" > dir1/.hgignore
  $ hg status
  ? dir1/file2
  ? dir1/subdir/file1
  ? dir2/file1
  $ rm dir1/subdir/file1

  $ echo "regexp:f.le1" > dir1/.hgignore
  $ hg status
  ? dir1/file2
  ? dir2/file1

Check multiple levels of sub-ignores

  $ 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 .
