wrapfunction: use functools.partial if possible

Every `extensions.bind` call inserts a frame in traceback:

   ... in closure
     return func(*(args + a), **kw)

which makes traceback noisy.

The Python stdlib has a `functools.partial` which is backed by C code and
does not pollute traceback. However it does not support instancemethod and
sets `args` attribute which could be problematic for alias handling.

This patch makes `wrapfunction` use `functools.partial` if we are wrapping a
function directly exported by a module (so it's impossible to be a class or
instance method), and special handles `wrapfunction` results so alias
handling code could handle `args` just fine.

As an example, `hg rebase -s . -d . --traceback` got 6 lines removed in my
setup:

     cmdpats, cmdoptions)
  -File "hg/mercurial/extensions.py", line 333, in closure

Clone with tags and branches works

  $ hg init remote-with-names
  $ cd remote-with-names
  $ echo 0 > foo
  $ hg -q commit -A -m initial
  $ echo 1 > foo
  $ hg commit -m 'commit 1'
  $ hg -q up 0
  $ hg branch mybranch
  marked working directory as branch mybranch
  (branches are permanent and global, did you want a bookmark?)
  $ echo 2 > foo
  $ hg commit -m 'commit 2 (mybranch)'
  $ hg tag -r 1 'default-tag'
  $ hg tag -r 2 'branch-tag'
