[OE-core] [PATCH] Add support for remote layering.

[Paul Eggleton]

Hi Jeremy

Have looked at this further and I really think this needs to be a separate 
utility, but one still written in python using bitbake's infrastructure (like 
bitbake-layers). The advantages of this approach:

1) Avoids reworking bitbake's initialisation and avoids possible re-execution. 
A separate utility can take advantage of a full parse and utilise all of the 
user's configuration.

2) Fetching/updating layers should be (able to be) a conscious action rather 
than something that happens implicitly as part of the build process

I'm trying to put something together that does this at the moment, with a view 
to there being components that allow integration with the content tools you 
posted earlier. Will keep you posted.

Cheers,
Paul
