bitbake: data_smart/cookerdata: Add variable remapping support

This change adds support for improving the user experience when variables
are renamed. This isn't as simple as it might first appear since some
bitbake variables are used through the environment before the datastore
exists, some are bitbake variables which we know about straight away
and some are metadata defined which we don't know about until later.

This patch adds support for handling these different cases, allowing a list
of bitbake renamed variables to be defined in bitbake itself and allows this
to be extended through the metadata using BB_RENAMED_VARIABLES.

In order to give the best feedback to the user, we default to turning on
variable history tracking in the base data store from knotty, which allows
filename and line number information to be shown.
