mq: use list of already known target files instead of matching object for diff

'hg qnew' passes matching object to 'patch.diff()' to specify target
filenames, and it causes 'dirstate.walk()' via 'repo.status()' in
'patch.diff()'.

but target files are already known before 'patch.diff()' invocation.

to avoid useless 'dirstate.walk()' invocation, this patch uses
'changes' argument to pass already known target files to
'patch.diff()' instead of 'match' argument.

'changes' argument of 'patch.diff()' should have lists for modified,
added and removed files separately, so this patch saves status of
'.hgsubstate' before commit, and put it into appropriate list in
'changes'.

  $ hg init

  $ echo a > a
  $ hg ci -qAm 'add a'

  $ hg init subrepo
  $ echo 'subrepo = http://example.net/libfoo' > .hgsub
  $ hg ci -qAm 'added subrepo'

  $ hg up -qC 0
  $ echo ax > a
  $ hg ci -m 'changed a'
  created new head

  $ hg up -qC 1
  $ cd subrepo
  $ echo b > b
  $ hg add b
  $ cd ..

Should fail, since there are added files to subrepo:

  $ hg merge
  abort: outstanding uncommitted changes in subrepository 'subrepo'
