Thrift: TDenseProtocol.

Summary:
- Made some stuff in TBinaryProtocol protected instead of private.
- Added a preliminary version of TDenseProtocol.  This is still
  super highly experimental and gross, and I wrote a super scary
  comment to explain that to anyone foolish enough to try to use
  this in its current state.

Test Plan: test/DenseProtoTest.cpp

Revert Plan: ok

Memcache Impact:
Save memory if/when people use it.
