Remove legacy code in wire_gen and protobuf_gen designed for global codegen strategy
Review Request #3123 - Created Nov. 14, 2015 and submitted
|benjyw, gmalmquist, jsirois, patricklaw|
The protobuf_parse code was not 100% reliable and since the advent of simple_codegen.py and the isolated build strategy
was no longer needed for codegen, just the conflicting protos check.
The conflicting protos check was only a problem with the global codegen strategy, so it turns out
that all of that code can go.
