classes/buildhistory: add new output history collection class

Create a new build output history reporting class, using testlab.bbclass
from meta-oe and packagehistory.bbclass as a base. This records information
from packages and images output from the build process in text files
structured suitably for tracking within a git repository, thus enabling
monitoring of changes over time.

Build history collection can be enabled simply by adding the following
to your local.conf:

INHERIT += "buildhistory"

The output after a build can then be found in BUILDHISTORY_DIR (defaults to
TMPDIR/buildhistory). If you set up this directory as a git repository and
set BUILDHISTORY_COMMIT to "1" in local.conf, the build history data will
be committed on every build.
