Default Perforce support for koji

The powers that be require us to use Perforce. Thus, the patch. A few
things to note about it:

* Our P4 server is running on a non-standard port and thus needs to be
specified. scm_tuple is now created via rsplit instead. Allows SCM
port to be specified. i.e. This now works:
allowed_scms=perforcetx.bluecoat.com:1999:/koji/sandbox/paul.schroeder/skeletor
* P4 *requires* a stinkin' password. So I added password support to
_parse_url. The "user" part of the SCM url can now be "userassword".
Still works minus the "assword" too. Let me know if there's a
better/preferred way to support passwords.
* P4 can only checkout into the static client root specified in the P4
client spec (PITA). Sooo.. After the module_checkout_cmd is executed,
if sourcedir does not exist, we do a 'os.rename' of the checked out code
into the proper task sourcedir.
* A P4 SCM URL looks like:
p4://userass@p4port/p4client/p4depot?path/to/module#changelist
i.e. p4port==host And p4client is your P4 client spec that you've
created.

Let me know if there are any Qs, comments, or any changes I should
make..

Cheers...Paul...
