buildhistory.bbclass: remove out-dated information on request
buildhistory.bbclass by design is incremental: each build adds or updates information. Information is never removed. Sometimes it can be useful to reduce the information only to those recipes that were build during a specific bitbake invocation, for example when the invocation does a full world build. This is now possible by setting BUILDHISTORY_RESET as explained in the modified class. The comment on the variable also mentions the caveats associated with using this mode. In this mode, buildhistory.bbclass first moves all existing information into a temporary directory called "old" inside the build history directory. There the information is used for the "version going backwards" QA check. Then when the build is complete and before (potentially) committing to git, the temporary directory gets deleted. Because information that has not changed during the build will be reconstructed during full world rebuilds, a git log will then only show real updates, additions and removals.
