* cygtls.h (struct _local_storage): Add thread storage pointers for

	memory used by socket select functions.  Combine them into a single
	struct select.
	* cygtls.cc: Accommodate above change throughout.
	(_cygtls::init_thread): Drop initalizing of sockevt to
	INVALID_HANDLE_VALUE.
	(_cygtls::fixup_after_fork): Reset sockevt to NULL.
	(_cygtls::remove): Don't use sockevt value to bail out prematurely.
	Set sockevt to NULL.  Free malloced select members.
	* select.h (struct select_socket_info): Drop max_w4 member.
	* select.cc (thread_socket): Use INFINITE timeout value if number of
	objects to wait for is <= MAXIMUM_WAIT_OBJECTS.  Use num_w4 member
	of select_socket_info struct rather than dropped max_w4.
	(init_tls_select_info): New inline function to initialize TLS select
	members.
	(start_thread_socket): Just call init_tls_select_info to initialize TLS
	select members and use them later on.
	(socket_cleanup): Don't free select_socket_info pointer members since
	they are thread local now.
