lock: fix for Mercurial 3.6+ - wrap hgweb to catch Locked exceptions from hooks

With Mercurial 3.6, the handling of WSGI responses changed. The hook exceptions
are no longer raised directly when app(environ, start_response) is called so
the 'except HTTPLockedRC as e' block in _handle_request (a few lines above )
does not work anymore because the exception happens later.

Therefore I created a wrapper class that can catch the exceptions.

This makes locking work again and fixes lock related tests like
TestVCSOperations.test_clone_after_repo_was_locked_hg which expect certain
output of the hg client in case of an HTTPLockedRC exception.

Depending on how https://bz.mercurial-scm.org/show_bug.cgi?id=5232 gets
handled, this fix might become obsolete in the future.
