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

MERCURIAL QUICK-START

Setting up Mercurial:

 Note: some distributions fails to include bits of distutils by
 default, you'll need python-dev to install. You'll also need a C
 compiler and a 3-way merge tool like merge, tkdiff, or kdiff3.

 First, unpack the source:

 $ tar xvzf mercurial-<ver>.tar.gz
 $ cd mercurial-<ver>

 When installing, change python to python2.3 or python2.4 if 2.2 is the
 default on your system.

 To install system-wide:

 $ python setup.py install --force

 To install in your home directory (~/bin and ~/lib, actually), run:

 $ python setup.py install --home=${HOME} --force
 $ export PYTHONPATH=${HOME}/lib/python  # (or lib64/ on some systems)
 $ export PATH=${HOME}/bin:$PATH         # add these to your .bashrc

 And finally:

 $ hg                                    # test installation, show help

 If you get complaints about missing modules, you probably haven't set
 PYTHONPATH correctly.

Setting up a Mercurial project:

 $ hg init project     # creates project directory
 $ cd project
                       # copy files in, edit them
 $ hg add              # add all unknown files
 $ hg remove --after   # remove deleted files
 $ hg commit           # commit all changes, edit changelog entry

 Mercurial will look for a file named .hgignore in the root of your
 repository which contains a set of regular expressions to ignore in
 file paths.

Branching and merging:

 $ hg clone linux linux-work    # create a new branch
 $ cd linux-work
 $ <make changes>
 $ hg commit
 $ cd ../linux
 $ hg pull ../linux-work     # pull changesets from linux-work
 $ hg merge                  # merge the new tip from linux-work into
                             # our working directory
 $ hg commit                 # commit the result of the merge

Importing patches:

 Fast:
 $ patch < ../p/foo.patch
 $ hg commit -A

 Faster:
 $ patch < ../p/foo.patch
 $ hg commit `lsdiff -p1 ../p/foo.patch`

 Fastest:
 $ cat ../p/patchlist | xargs hg import -p1 -b ../p

Exporting a patch:

 (make changes)
 $ hg commit
 $ hg tip
 28237:747a537bd090880c29eae861df4d81b245aa0190
 $ hg export 28237 > foo.patch    # export changeset 28237

Network support:

 # pull from the primary Mercurial repo
 foo$ hg clone http://selenic.com/hg/
 foo$ cd hg

 # export your current repo via HTTP with browsable interface
 foo$ hg serve -n "My repo" -p 80

 # pushing changes to a remote repo with SSH
 foo$ hg push ssh://[e-mail]/~/hg/

 # merge changes from a remote machine
 bar$ hg pull http://foo/
 bar$ hg merge   # merge changes into your working directory

 # Set up a CGI server on your webserver
 foo$ cp hgweb.cgi ~/public_html/hg/index.cgi
 foo$ emacs ~/public_html/hg/index.cgi # adjust the defaults
