hgweb: establish class for holding per request context

Currently, hgweb applications have many instance variables holding
mutated state. This is somewhat problematic because multiple threads
may race accessing or changing this state.

This patch starts a series that will add more thread safety to
hgweb applications. It will do this by moving mutated state out
of hgweb and into per-request instances of the newly established
"requestcontext" class.

Our new class currently behaves like a proxy to hgweb instances. This
should change once all state is captured in it instead of hgweb. The
effectiveness of this proxy is demonstrated by passing instances of
it - not hgweb instances/self - to various functions.

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()

# enable demandloading to reduce startup time
