bitbake: cooker: Use multiple BuildStarted events for multiconfig

Currently builds in multiple TMPDIRs with multiconfig can break
since the BuildStarted event is used to create directory strutures in several
cases (e.g. buildstats.bbclass) and there is only on BuildStarted event
generated in a multiconfig build.

We have two options, a) to add a new MultiConfigBuildStarted event which is
generated once per multiconfig, or b) allow multiple BuildStarted events.

Having reviewed the code and current users of BuildStarted, sending one event
per multiconfig seems like its the best way forward and the existing code looks
able to cope with the duplication of events. I did also check toaster and I think
that can handle this issue too (multiconfig builds may have other issues there).

I'm therefore proposing we send multiple BuildStarted events for multiconfig
and for consistency, send multiple BuildCompleted events too.

We need to ensure that BUILDNAME, BUILDSTART and DATE/TIME are set consistently
in all the different multiconfig datastores. These events can write to the
datastore so copies are not used. buildFile was also cleaned up to ensure it
uses the right datastore in various places.
