annotate mercurial/hg.py @ 2506:d0db3462d568

This patch make several WSGI related alterations.

First, it changes the server to be almost a generic WSGI server.

Second, it changes request.py to have wsgiapplication and
_wsgirequest.  wsgiapplication is a class that creates _wsgirequests
when called by a WSGI compliant server.  It needs to know whether
or not it should create hgwebdir or hgweb requests.

Lastly, wsgicgi.py is added, and the CGI scripts are altered to
use it to launch wsgiapplications in a WSGI compliant way.

As a side effect, all the keepalive code has been removed from
request.py.  This code needs to be moved so that it is exclusively
in server.py
