largefiles: improve repo wrapping detection

Before this patch, repo wrapping detection in "reposetup()" of
largefiles can detect only limited repo wrapping: replacing target
functions by another one named as "wrap".

So, it can't detect repo wrapping even in recommended style: replacing
"__class__" of repo by derived class.

This patch can detect repo wrapping in both styles below:

  - replacing "__class__" of repo by derived class (recommended style):

        class derived(repo.__class__):
            def push(self, *args, **kwargs):
                return super(derived, self).push(*args, **kwargs)
        repo.__class__ = derived

  - replacing function of repo by another one (not recommended style):

        orgpush = repo.push
        def push(*args, **kwargs):
            return orgpush(*args, **kwargs)
        repo.push = push

import sys

globalvars = {}
localvars = {}
lines = sys.stdin.readlines()
while lines:
    l = lines.pop(0)
    if l.startswith('SALT'):
        print l[:-1]
    elif l.startswith('>>> '):
        snippet = l[4:]
        while lines and lines[0].startswith('... '):
            l = lines.pop(0)
            snippet += "\n" + l[4:]
        c = compile(snippet, '<heredoc>', 'single')
        try:
            exec c in globalvars, localvars
        except Exception, inst:
            print repr(inst)
