[OE-core] [PATCH] buildhistory.bbclass: metadata-revs show repo parent

[Trevor Woerner]

To me, the purpose of buildhistory's metadata-revs is to enable someone 
else (or myself in the future) to recreate a specific build, that's why 
I always save this file with any build artifacts. Simply saying "meta" 
isn't good enough because it doesn't specify which repository's "meta". 
So the purpose of this patch is to try to clarify which repositories 
we're talking about.

I have a second patch, now, that will generate the following output, 
which I think is even better:

     git://git.openembedded.org/openembedded-core.git
     openembedded-core/meta = 
master:00d3fd571a8d261d065b43f5cf3076a381843984

Frankly, there are too many forks and clones. There are too many 
meta-beaglebone or meta-odroid or meta-raspberrypi repositories. If six 
months from now I want to recreate a build I've done today, I'll need to 
know the repository, where it's from, and which commit was checked out. 
My latest patch provides that information.

Is this better?
