buildhistory analysis

The first part of the buildhistory analysis functionality (command-line only at the moment). It hasn't been heavily tested "in anger" yet (I hope we will start to use it on the Yocto Project autobuilder fairly soon) but it is functional.

There are also a couple of improvements to buildhistory.bbclass itself.

The following changes since commit 563828bad19a242bba9ce3db461bb5807037dfdf:

multilib: Abstract class extension code into classextend.py (2012-01-05 12:36:08 +0000)
