transaction: use a ".bck" extension for all backup file

There are too much code in Mercurial that assume file function from extension.
Keeping the original extension when doing backup is just creating confusion
(for exemple, backup of revlog's confused with new version revlogs).

So we change the backup name from now on to be explicilty backup file and
prevent this kind of problem.

(note that repository using fncache is less affected (but still affected) by
this kind of problem as the backup are not listed in the fncache).

commit hooks can see env vars
(and post-transaction one are run unlocked)

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

  $ 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
