* fhandler.h (fhandler_socket::recv_internal): Add bool parameter.

Browse Source 
Add regparm attribute.
	* fhandler_socket.cc (fhandler_socket::read): Call recv_internal with
	second parameter set to false.
	(fhandler_socket::readv): Ditto.
	(fhandler_socket::recvfrom): Ditto.
	(fhandler_socket::recv_internal): Convert use_recvmsg from local
	variable to parameter.  Use as request for using WSARecvMsg.  Only
	fail if WSARecvMsg can't be loaded and wsamsg->Control.len > 0,
	otherwise use WSARecv{From}.  Restrict dwFlags to MSG_PEEK when using
	WSARecvMsg.
	(fhandler_socket::recvmsg): Prefer using WSARecvMsg.  Change priority
	of tests for not using WSARecvMsg.  Call recv_internal with second
	parameter set accordingly.
