uncommit: move fb-extension to core which uncommits a changeset

uncommit extension in fb-hgext adds a uncommit command which by default
uncommits a changeset and move all the changes to the working directory. If
file names are passed, uncommit moves the changes from those files to the
working directory and left the changeset with remaining committed files.

The uncommit extension in fb-hgext does not creates an empty commit like the one
in evolve extension unless user has specified ui.alllowemptycommit to True.

The test file added is a combination of tests from test-uncommit.t,
test-uncommit-merge.t and test-uncommit-bookmark.t from fb-hgext.

.. feature::

   A new uncommit extension which provides `hg uncommit` using which one can
   uncommit part or all of the changeset. This command undoes the effect of a
   local commit, returning the affected files to their uncommitted state.

Differential Revision: https://phab.mercurial-scm.org/D529

Set up a base, local, and remote changeset, as well as the working copy state.
Files names are of the form base_remote_local_working-copy. For example,
content1_content2_content1_content2-untracked represents a
file that was modified in the remote changeset, left untouched in the
local changeset, and then modified in the working copy to match the
remote content, then finally forgotten.

  $ hg init repo
  $ cd repo

Create base changeset

  $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 1
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'base'

Create remote changeset

  $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 2
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'remote'

Create local changeset

  $ hg update -q 0
  $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 3
  $ hg addremove -q --similarity 0
  $ hg commit -qm 'local'

Set up working directory

  $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 wc
  $ hg addremove -q --similarity 0
  $ hg forget *_*_*_*-untracked
  $ rm *_*_*_missing-*

  18 files updated, 3 files merged, 8 files removed, 35 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon

Check which files need to be resolved (should correspond to the output above).
This should be the files for which the base (1st filename segment), the remote
(2nd segment) and the working copy (4th segment) are all different.

Interestingly, one untracked file got merged and added, which corresponds to the
odd 'if force and branchmerge and different' case in manifestmerge().

Check status and file content

Some files get added (e.g. content1_content2_content1_content1-untracked)

It is not intuitive that content1_content2_content1_content4-tracked gets
merged while content1_content2_content1_content4-untracked gets overwritten.
Any *_content2_*-untracked triggers the modified/deleted prompt and then gets
overwritten.

A lot of untracked files become tracked, for example
content1_content2_content2_content2-untracked.

*_missing_missing_missing-tracked is reported as removed ('R'), which
doesn't make sense since the file did not exist in the parent, but on the
other hand, merged-in additions are reported as modifications, which is
almost as strange.

missing_missing_content3_missing-tracked becomes removed ('R'), even though
the remote side did not touch the file
