[RFC PATCH 0/2] skipped recipe handling

[Paul Eggleton <paul.eggleton@linux.intel.com>]

I noticed bitbake-layers did not handle bbappends for skipped recipes
properly (e.g. in Poky it complained that uclibc_git.bbappend did not
match any recipe). Thus I added a mechanism to bitbake within cooker that
lists skipped recipes and extended bitbake-layers to use it.

This (or something similar) will also be needed for improving the
NoProvider error handling - ideally we should be reporting if the target
being requested has been skipped and why. To this end the SkippedPackage
class includes the reason and DEPENDS/RDEPENDS info (although at the
moment RDEPENDS does not get populated). Some may prefer I remove the 
DEPENDS/RDEPENDS bits until the future patch where they are used, if
so I wouldn't object to removing them.

I also considered adding to skiplist for BBMASKed-out recipes but on
reflection I elected not to do so since I assumed we ought to be
completely ignoring recipes that are masked out in this way.

Patch summary (these are against Poky but they apply cleanly with -p2
against bitbake master):

Paul Eggleton (2):
  bitbake: track skipped packages
  bitbake-layers: handle skipped recipes
