* event-loop.c (event_handle_func): Adjust to use gdb_fildes_t.

	(struct gdb_event) <fd>: Change type to gdb_fildes_t.
	(struct file_handler) <fd>: Change type to gdb_fildes_t.
	(process_event): Change local fd's type to gdb_fildes_t.
	(create_file_handler): Adjust prototype.
	(delete_file_handler): Adjust prototype.
	(handle_file_event): Adjust prototype.  Use pfildes.
	(create_file_event): Adjsut prototype.
	* remote-utils.c (remote_desc, listen_desc): Change type to
	gdb_fildes_t.
	* server.h: New gdb_fildes_t typedef.
	[USE_WIN32API]: Include winsock2.h.
	(delete_file_handler, add_file_handler): Adjust prototypes.
