match: add the abs() method

This is a utility to make it easier for subrepos to convert a file name to the
full path rooted at the top repository.  It can replace the various path joining
lambdas, and doesn't require the prefix to be passed into the method that wishes
to build such a path.

The name is derived from the following pattern in annotate() and other places:

        name = ((pats and rel) or abs)

The pathname separator is not os.sep in part to avoid confusion with variables
named 'abs' or similar that _are_ '/' separated, and in part because some
methods like cmdutils.forget() and maybe cmdutils.add() need to build a '/'
separated path to the root repo.  This can replace the manual path building
there.

Make sure that the internal merge tools (internal:fail, internal:local, and
internal:other) are used when matched by a merge-pattern in hgrc

Make sure HGMERGE doesn't interfere with the test:

  $ unset HGMERGE

  $ hg init

Initial file contents:

  $ echo "line 1" > f
  $ echo "line 2" >> f
  $ echo "line 3" >> f
  $ hg ci -Am "revision 0"
  adding f

  $ cat f
  line 1
  line 2
  line 3

Branch 1: editing line 1:

  $ sed 's/line 1/first line/' f > f.new
  $ mv f.new f
  $ hg ci -Am "edited first line"

Branch 2: editing line 3:

  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ sed 's/line 3/third line/' f > f.new
  $ mv f.new f
  $ hg ci -Am "edited third line"
  created new head

Merge using internal:fail tool:

  $ echo "[merge-patterns]" > .hg/hgrc
  $ echo "* = internal:fail" >> .hg/hgrc

  $ hg merge
  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon
  [1]

  $ cat f
  line 1
  line 2
  third line

  $ hg stat
  M f

Merge using internal:local tool:

  $ hg update -C 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ sed 's/internal:fail/internal:local/' .hg/hgrc > .hg/hgrc.new
  $ mv .hg/hgrc.new .hg/hgrc

  $ hg merge
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ cat f
  line 1
  line 2
  third line

  $ hg stat
  M f

Merge using internal:other tool:

  $ hg update -C 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ sed 's/internal:local/internal:other/' .hg/hgrc > .hg/hgrc.new
  $ mv .hg/hgrc.new .hg/hgrc

  $ hg merge
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ cat f
  first line
  line 2
  line 3

  $ hg stat
  M f

Merge using default tool:

  $ hg update -C 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm .hg/hgrc

  $ hg merge
  merging f
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ cat f
  first line
  line 2
  third line

  $ hg stat
  M f
