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:

(Should test similar mergeto feature, but I don't understand it yet.)
Requires builtin cvsps.
