filemerge: add non-interactive :merge-local and :merge-other

There are two non-interactive internal merge tools, :other and :local,
but they don't really merge, they just pick all changes from the local
or other version of the file. In some situations, it is known that we
want a merge and also know that all merge conflicts should be resolved
in one direction. Although external merge tools can do this, sometimes
it can be convenient to do so from within hg, without invoking a merge
tool. These new :merge-local and :merge-other tools can do just that.

Add some unconflicting changes on each head, to make sure we really
are merging, unlike :local and :other

  $ hg up -C
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ printf "\n\nEnd of file\n" >> a
  $ hg ci -m "Add some stuff at the end"
  $ hg up -r 1
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ printf "Start of file\n\n\n" > tmp
  $ cat a >> tmp
  $ mv tmp a
  $ hg ci -m "Add some stuff at the beginning"

Now test :merge-other and :merge-local

  $ hg merge
