url: add --insecure option to bypass verification of ssl certificates
If --insecure specified, it behaves in the same way as no web.cacerts
configured.
Also shows hint for --insecure option when _verifycert() failed. But currently
the hint isn't displayed on SSLError, because it needs a certain level of
changes.

The wrapper will be called like

are the arguments passed to it.
Wrapping methods of the repository object is not recommended since
it conflicts with extensions that extend the repository by
subclassing. All extensions that need to extend methods of
localrepository should use this subclassing trick: namely,
reposetup() should look like
def reposetup(ui, repo):
class myrepo(repo.__class__):
def whatever(self, *args, **kwargs):
[...extension stuff...]
super(myrepo, self).whatever(*args, **kwargs)
[...extension stuff...]
repo.__class__ = myrepo
In general, combining wrapfunction() with subclassing does not
work. Since you cannot control what other extensions are loaded by
your end users, you should play nicely with others by using the
subclass trick.
