In OpenEmbedded's buildhistory class we want access to the bitbake command line that launched the build, and up to now we were simply using sys.argv from within the event handler to get that. Unfortunately that doesn't work in memory resident mode, since the event handler is naturally executing within the server and thus will give you the command that launched the bitbake server which is much less interesting. Add a dynamic variable BB_CMDLINE to provide access to this, set from sys.argv within the UI process in updateToServer(). (Note that BB_CMDLINE isn't currently passed through to the worker, so this is only really readable from event handlers plus any explicit getVariable calls - in theory an observe-only UI could read it for example.) Part of the fix for [YOCTO #11634].
