[OE-core] preferred remotes for git pulls?

[Peter A. Bigot]

There are two changes (virtual/bluez and pseudo-no-host-passwd) that I'd 
like to rework and propose for master now that it's reopened.  Both are 
likely to touch multiple files.  Previous comments and the wiki how-to 
suggest that git-pull is preferred over patchwork-only for multi-patch 
changes like this.

I have existing github resources that I could use as the source. Would 
that be acceptable to the maintainers?

If using an openembedded-hosted -contrib repository is preferred, what's 
the process for getting access?  I'd be touching openembedded-core and 
meta-openembedded at the least.
