cpp: Eliminate circular dependency between thrift libraries
Previously, Thrift.cpp contained TApplicationException, which was using
TProtocol methods, defined in TProtocol.h. This caused a circular
dependency since libprotocol depends on Thrift.h. This change moves
TApplicationException into its own file.
