Drop usage of old-age BSD types in generically used Cygwin headers

Browse Source 
u_char, u_short, u_int, u_long are BSD-only types.  Remove them from
Cygwin headers which are supposed to be used in a non-BSD scenario.
Drop special Cygwin handling of those types in sys/types.h.

newlib:
	* libc/include/sys/types.h (u_char,u_short,u_int,u_long): Drop
	Cygwin exception.

cygwin:
	* fhandler_socket.cc (fhandler_socket::ioctl): Accommodate change
	in include/asm/socket.h.  Continue using u_long since that's the
	MS type here.
	* include/asm/socket.h: Since the type given in _IOR/_IOW macros
	is only used for its sizeof, replace u_long with equivalent long.
	* netdb.h (getnetbyaddr): Fix prototype.
	* netinet/ip.h: Replace old BSD-only types with generically defined
	old BSD types (u_char -> u_int8_t, etc).
	* netinet/tcp.h: Ditto.
	* netinet/udp.h: Ditto.
