For protocol buffer files, when there were gpb options to alter the
module name with prefix or suffix, recompilation was not properly
detected. This is now fixed. (Issue #384).
Properly detecting change meant moving from rebar_base_compiler, so it
also meant processing protocol buffer files in sequence instead of in
parallel.

The bulk of these tests are written by Luis Rascão, hence he is the
author of this commit. As the committer, I have cherry-picked his two
commits 4c87bcd and ebb8182, from the feature/support_gpb_protobuf
branch in the git://github.com/lrascao/rebar repo, and have slightly
adapted it to fit this pluggable-proto-compilers-gpb branch.
