Issue1827: Hooks Update & Commit not completely post operation

commit and update hooks should run after command completion.  The largefiles
use demonstrates a recursive wlock, showing the hook doesn't run until the
final release (and dirstate flush).

  $ echo '[hooks]' > .hg/hgrc
  $ echo 'commit = hg id' >> .hg/hgrc
  $ echo 'update = hg id' >> .hg/hgrc
  $ echo bb > a
  $ hg ci -ma
  223eafe2750c tip
  $ hg up 0 --config extensions.largefiles=
  The fsmonitor extension is incompatible with the largefiles extension and has been disabled. (fsmonitor !)
  cb9a9f314b8b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

make sure --verbose (and --quiet/--debug etc.) are propagated to the local ui
that is passed to pre/post hooks

  $ echo '[hooks]' > .hg/hgrc
  $ echo 'pre-identify = python:hooktests.verbosehook' >> .hg/hgrc
  $ hg id
  cb9a9f314b8b
  $ hg id --verbose
  calling hook pre-identify: hooktests.verbosehook
  verbose output from hook
  cb9a9f314b8b

Ensure hooks can be prioritized

  $ echo '[hooks]' > .hg/hgrc
  $ echo 'pre-identify.a = python:hooktests.verbosehook' >> .hg/hgrc
  $ echo 'pre-identify.b = python:hooktests.verbosehook' >> .hg/hgrc
  $ echo 'priority.pre-identify.b = 1' >> .hg/hgrc
  $ echo 'pre-identify.c = python:hooktests.verbosehook' >> .hg/hgrc
  $ hg id --verbose
  calling hook pre-identify.b: hooktests.verbosehook
  verbose output from hook
  calling hook pre-identify.a: hooktests.verbosehook

  calling hook pre-identify.c: hooktests.verbosehook

  $ hg tag -f foo
