pcmcia: Change window_handle_t logic to unsigned long

Logic changes based on top of the other patches:

This set of patches changed window_handle_t from being a pointer to an
unsigned long. The unsigned long is now a simple index into socket->win[].
Going from a pointer to unsigned long should leave the user space interface
unchanged unless I'm mistaken.

This change results in code that is less error prone and a user space
interface which is much cleaner and safer. A nice side effect is that we
are also are able to remove all members except one from window_t.

[ linux@dominikbrodowski.net:
	Update to 2.6.31. Also, a plain "index" to socket->win[] does not
	work, as several codepaths rely on "window_handle_t" being
	non-zero if used. Therefore, set the window_handle_t to the
	socket->win[] index + 1. ]
