[PATCH 3/3] bugzilla.bbclass: add a class to report build problems to bugzilla

[Dmitry Eremin-Solenikov <dbaryshkov@gmail.com>]

Add a class to report build errors to bugzilla. Idea largely based on
sepukku.bbclass, however it's rewritten nearly fully to use XML-RPC
interface of bugzilla. Tested with bugzilla 4.0, other version might
require some sort of adaptation.
