devserver: general cleanup
* Unified logging API via module/class-local _Log() calls.
* Renamed modules: devserver_util --> common_util (this is the common
util module, and it saves a lot of characters in many places);
downloadable_artifact --> build_artifact (we don't have any
non-downloadable artifacts); buildutil.py --> build_util.py (for
uniformity)
* Reorganized Artifact (now BuildArtifact) class hierarchy to properly
reflect the inheritance chains.
