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:

   File "hg/mercurial/dispatch.py", line 898, in _dispatch
     cmdpats, cmdoptions)
  -File "hg/mercurial/extensions.py", line 333, in closure

Add a .hgignore so that we can also have ignored files

  $ echo ".*\.o" > .hgignore
  $ hg status
  ? .hgignore
  ? a
  ? b
  $ hg status -i
  I x/aa.o
  I x/bb.o

Tersing ignored files
  $ hg status -t i --ignored
  I x/

Adding more files
  $ mkdir y
  $ touch x/aa x/bb y/l y/m y/l.o y/m.o
  $ touch x/l/aa x/m/aa x/n/aa x/l/u/bb x/l/u/a/bb

  $ hg status
  ? .hgignore
  ? a
  ? b
  ? x/aa
  ? x/bb
  ? x/l/aa
  ? x/l/u/a/bb
  ? x/l/u/bb
  ? x/m/aa
  ? x/n/aa
  ? y/l
  ? y/m

  $ hg status --terse u
  ? .hgignore
  ? a
  ? b
  ? x/
  ? y/

  $ hg add x/aa x/bb .hgignore
  $ hg status --terse au
  A .hgignore
  A x/aa
  A x/bb
  ? a
  ? b
  ? x/l/
  ? x/m/
  ? x/n/
  ? y/

Including ignored files

  $ hg status --terse aui
  A .hgignore
  A x/aa
  A x/bb
  ? a
  ? b
  ? x/l/
  ? x/m/
  ? x/n/
  ? y/l
  ? y/m
  $ hg status --terse au -i
  I x/aa.o
  I x/bb.o
  I y/l.o
  I y/m.o

Committing some of the files

  $ hg commit x/aa x/bb .hgignore -m "First commit"
  $ hg status
  ? a
  ? b
  ? x/l/aa
  ? x/l/u/a/bb
  ? x/l/u/bb
  ? x/m/aa
  ? x/n/aa
  ? y/l
  ? y/m
  $ hg status --terse mardu
  ? a
  ? b
  ? x/l/
  ? x/m/
  ? x/n/
  ? y/

Modifying already committed files

  $ echo "Hello" >> x/aa
  $ echo "World" >> x/bb
  $ hg status --terse maurdc
  M x/aa
  M x/bb
  ? a
  ? b
  ? x/l/
  ? x/m/
  ? x/n/
  ? y/

Respecting other flags

  $ hg status --terse marduic --all
  M x/aa
  M x/bb
  ? a
  ? b
  ? x/l/
  ? x/m/
  ? x/n/
  ? y/l
  ? y/m
  I x/aa.o
  I x/bb.o
  I y/l.o
  I y/m.o
  C .hgignore
  $ hg status --terse marduic -a
  $ hg status --terse marduic -c
  C .hgignore
  $ hg status --terse marduic -m
  M x/aa
  M x/bb

Passing 'i' in terse value will consider the ignored files while tersing

  $ hg status --terse marduic -u
  ? a
  ? b
  ? x/l/
  ? x/m/
  ? x/n/
  ? y/l
  ? y/m

Omitting 'i' in terse value does not consider ignored files while tersing

  $ hg status --terse marduc -u
  ? a
  ? b
  ? x/l/
  ? x/m/
  ? x/n/
  ? y/

Trying with --rev

  $ hg status --terse marduic --rev 0 --rev 1
  abort: cannot use --terse with --rev
