treemanifest: allow manifestrevlog to take an explicit treemanifest arg

Previously we relied on the opener options to tell the revlog to be a tree
manifest. This makes it complicated for extensions to create treemanifests and
normal manifests at the same time. Let's add a construtor argument to create a
treemanifest revlog as well.

I considered removing the options['treemanifest'] logic from manifestrevlog
entirely, but doing so shifts the responsibility to the caller which ends up
requiring changes in localrepo, bundlerepo, and unionrepo. I figured having the
dual mechanism was better than polluting other parts of the code base with
treemanifest knowledge.

# A dummy extension that installs an hgweb command that throws an Exception.

from __future__ import absolute_import

from mercurial.hgweb import (
    webcommands,
)

def raiseerror(web, req, tmpl):
    '''Dummy web command that raises an uncaught Exception.'''

    # Simulate an error after partial response.
    if 'partialresponse' in req.form:
        req.respond(200, 'text/plain')
        req.write('partial content\n')

    raise AttributeError('I am an uncaught error!')

def extsetup(ui):
    setattr(webcommands, 'raiseerror', raiseerror)
    webcommands.__all__.append('raiseerror')
