git-cvsimport: add support for CVS pserver method HTTP/1.x proxying
This patch adds support for 'proxy' and 'proxyport' connection options when using the pserver method for the CVS Root. It has been tested with a Squid 2.5.x proxy server. Quoting from the CVS info manual: The `gserver' and `pserver' connection methods all accept optional method options, specified as part of the METHOD string, like so: :METHOD[;OPTION=ARG...]: Currently, the only two valid connection options are `proxy', which takes a hostname as an argument, and `proxyport', which takes a port number as an argument. These options can be used to connect via an HTTP tunnel style web proxy. For example, to connect pserver via a web proxy at www.myproxy.net and port 8000, you would use a method of: :pserver;proxy=www.myproxy.net;proxyport=8000: *NOTE: The rest of the connection string is required to connect to the server as noted in the upcoming sections on password authentication, gserver and kserver. The example above would only modify the METHOD portion of the repository name.* PROXY must be supplied to connect to a CVS server via a proxy server, but PROXYPORT will default to port 8080 if not supplied. PROXYPORT may also be set via the CVS_PROXY_PORT environment variable. Signed-off-by: Iñaki Arenaza <iarenuno@eteo.mondragon.edu> Signed-off-by: Junio C Hamano <junkio@cox.net>
