Thrift: Debug Protocol

Summary:
Added TDebugProtocol, a write-only Thrift protocol for C++
that produces human-readable representations of thrift structs.

Trac Bug: #

Blame Rev:

Reviewed By: mcslee

Test Plan:
Recompiled Thrift.
./test/TestDebugProto.* see compile instructions at the top.
Ran that, and it looked good.

Revert Plan:
grep TDebugProtocol <world>
grep ThriftDebugString <world>
Revert or comment out whatever you find so that they still compile.
Then svn revert.
