Subject: [PATCH 13/33] thrift: fix processor inheritance

Summary:
I don't see any reason why all of the generated processor classes
multiply inherit from TProcessor via all of their parent classes.
This eliminates the virtual inheritance by changing the code so that
only the first class in the heirarchy inherits from TProcessor or
TAsyncProcessor.

As part of this change, we now have to explicitly write
"this->eventHandler_" instead of just "eventHandler_" so that the
compiler can tell that this is an inherited member variable when we are
generating template code.

Test Plan:
Built [internal fb thing] and a few other projects, and everything compiled fine.
I haven't done much actual RPC testing.

Revert Plan:
OK
