url: use CONNECT for HTTPS connections through HTTP proxy (issue967)

urllib2 and httplib does not support using CONNECT proxy requests, but
only regular requests over the proxy. This does not work with HTTPS
requests as they typically require that the client issues a CONNECT to
the proxy to give a direct connection to the remote HTTPS server.

This is solved by duplicating some of the httplib functionality and
tying it together with the keepalive library such that a HTTPS
connection that need to be proxied can be proxied by letting a
connection be established to the proxy server and then subsequently
performing the normal request to the specified server through the
proxy server.

As it stands, the code also purports to support HTTPS proxies, i.e.
proxies that you connect to using SSL. These are extremely rare and
nothing is done to ensure that CONNECT requests can be made to these
as that would require multiple SSL handshakes. This use case is also
not supported by most other contemporary web tools like curl and
Firefox3.

# The config file looks like this.  You can have paths to individual
# repos, collections of repos in a directory tree, or both.
#
# [paths]
# virtual/path1 = /real/path1
# virtual/path2 = /real/path2
# virtual/root = /real/root/*
# / = /real/root2/*
# virtual/root2 = /real/root2/**
#
# [collections]
# /prefix/to/strip/off = /root/of/tree/full/of/repos
#
# paths example: 
#
# * First two lines mount one repository into one virtual path, like
# '/real/path1' into 'virtual/path1'.
#
# * The third entry mounts every mercurial repository found in '/real/root'
# in 'virtual/root'. This format is preferred over the [collections] one,
# since using absolute paths as configuration keys is not supported on every
# platform (especially on Windows).
#
# * The fourth entry is a special case mounting all repositories in
# /'real/root2' in the root of the virtual directory.
#
# * The fifth entry recursively finds all repositories under the real root,
# and mounts them using their relative path (to given real root) under the
# virtual root.
#
# collections example: say directory tree /foo contains repos /foo/bar,
# /foo/quux/baz.  Give this config section:
#   [collections]
#   /foo = /foo
# Then repos will list as bar and quux/baz.
#
# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'
