url: support auth.cookiesfile for adding cookies to HTTP requests
Mercurial can't currently send cookies as part of HTTP requests.
Some authentication systems use cookies. So, it seems like adding
support for sending cookies seems like a useful feature.
This patch implements support for reading cookies from a file
and automatically sending them as part of the request. We rely
on the "cookiejar" Python module to do the heavy lifting of
parsing cookies files. We currently only support the Mozilla
(really Netscape-era) cookie format. There is another format
supported by cookielib and we may want to consider using that,
especially since the Netscape cookie parser can't parse ports.
It wasn't immediately obvious to me what the format of the other
parser is, so I didn't know how to test it. I /think/ it might
be literal "Cookie" header values, but I'm not sure. If it is
more robust than the Netscape format, we may want to just
support it.
httpconnection: allow a global auth.cookiefile config entry
This foreshadows support for defining a cookies file.
util: make cookielib module available
In preparation for supporting sending cookies on HTTP requests.
crecord: avoid setting non-existing SIGTSTP signal on windows (
issue5512)
Windows do not have a SIGTSTP so we avoid setting the handler if the signal is
unknown.
crecord: ensure we reinstall the SIGTSTP handler
Previous, exceptions would prevent the reinstallation of the
signal.
