Revision 666417

Change alterl thrift_server to use non-blocking TCP calls and properly set the processor as the controlling process for the client sockets.

Summary:
  - Removes the non-OTP "acceptor" process
  - The processor becomes the socket's controlling process instead of the transport, which is kind of messy, but it means we don't have to make a process for the socket_transport.
  - See http://www.trapexit.org/Building_a_Non-blocking_TCP_server_using_OTP_principles for non-blocking server info

Test plan:
  - Ran ThriftTest and StressTest
