While going through the backlog I ran across the 'git' versions of the
user space. I noticed that a recent contribution was adding a patch to
the git recipe and I figured that this patch would already be upstream
and so wouldn't be necessary. Not so. The 'git' versions have SRCREV
hard wired (SRCREV) to a commit id but it's way back from the end of
2013. They're also disabled via DEFAULT_PREFERENCE = "-1"

These 'git' versions seem super useful for testing bleeding edge stuff
so IMHO keeping them around would be the right thing to do. Not sure how
I feel about them tracking an ancient commit though. Since they're never
built by default it seems reasonable to track the master branch.

What's our philosophy w/r to recipes that pull from git? Is there some
history behind this SRCREV?

Thanks,
Philip
