Subject: Implement a feature to generate a dependency file. By giving protoc
 the flag "--dependency_manifest_out=FILE", protoc will write dependencies of
 input proto files into FILE. In FILE, the format will be <full path to FILE>:
 <full path to 1st proto>\\\n <full path to 2nd proto> ... This cl is based on
 https://github.com/google/protobuf/pull/178
