dirs._addpath: reinstate use of Py_CLEAR

I changed this to an explicit Py_DECREF + set to null in 6f0e6fa9fdd7. This was
a silly misunderstanding on my part -- for some reason I thought Py_CLEAR set
its argument to null only if its refcount reached 0. Turns out that's not
actually the case -- Py_CLEAR is just Py_DECREF + set to null with some
additional precautions around destructors that aren't relevant here.

The real bug that 6f0e6fa9fdd7 fixed was the fact that we were mutating the
string after setting it in the Python dictionary.

Issue1827: Hooks Update & Commit not completely post operation

commit and update hooks should run after command completion

  $ 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
  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
