commit: abort on merge with missing files

Here is a script illustrating the previous behaviour:

The merge brings a new file 'b' from remote
  $ hg merge 1 --debug
    searching for copies back to rev 1
    unmatched files in other:
     b
  resolving manifests
   overwrite: False, partial: False
   ancestor: 07f494440405, local: 540395c44225+, remote: 102a90ea7b4a
   b: remote created -> g
  updating: b 1/1 files (100.00%)
  getting b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

Delete but do not remove b
  $ rm b
  $ hg st
  ! b

The commit succeeds
  $ hg commit -m merge
  $ hg parents --template "{rev} {desc|firstline} files: {files}\n"
  3 merge files:
  $ hg st
  ! b

b changes were ignored, but even b existence was ignored
  $ hg manifest
  a

This happens because localrepo.commitctx() checks the input ctx.files(), which
is empty for workingctx.files() only returns added, modified or removed
entries, and bypass files/manifest updates completely. So the committed
revision manifest is the same as its first parent one, not containing the 'b'
file.

This patch forces the commit to abort in presence of a merge and missing files.
test-merge4.t is modified accordingly as it was introduced to check hg was not
just terminating with a traceback (5e9e8b8d2629).

  $ echo "[extensions]" >> $HGRCPATH

  $ hg init

  $ echo qqq>qqq.txt

rollback dry run without rollback information

  $ hg rollback

commit first revision

  $ hg ci -m 1

set bookmark

  $ hg book test

  $ echo www>>qqq.txt

commit second revision

  $ hg ci -m 2

set bookmark

  $ hg book test2

update to -2 (inactives the active bookmark)

  $ hg update -r -2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ echo eee>>qqq.txt

commit new head

  $ hg ci -m 3
  created new head

bookmarks updated?

  $ hg book

immediate rollback and reentrancy issue
