[p2-dev] Multi-agent support released into p2 branch

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

I have released a first cut at support
for multiple p2 agents in the same framework instance. This is available
in the p2 development branch (R3_6_api_cleanup). I have focused mainly
on the basic pieces (engine, director, publisher, repository managers),
and have only done basic testing. All tests are passing, which means the
"single agent" use case is still working, but the tests aren't
thoroughly exercising the multiple agent code paths yet (apart from the
director app tests). In any case, it's in good enough shape for people
to try it out and report bugs and give feedback. I know PDE and Buckminster
have some use cases for this support so hopefully they find it helpful.
