[PATCH 0/5] Refactoring + improve bitbake-diffsigs

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

Refactor out a class which can be used as the basis for bitbake-based
utilities, and use it to improve bitbake-diffsigs to enable easily
specifying a recipe and task and determine what the difference was in
the signature data between the last two executions.

This change requires some support code within the metadata (since
BitBake itself knows nothing about the implementation of shared state);
a patch to implement this in OE-Core has been sent to the OE-Core
mailing list.

Note that this is similar in spirit but does not directly overlap with
Robert's bitbake-whatchanged script - that allows you to determine what
will be done before it happens, whereas this tool is useful for
determining why a rebuild occurred afterwards.


The following changes (against poky, but apply cleanly with -p2 against 
bitbake master) are available in the git repository at:
