Staging: dt3155: replace u_int and u_long usage

  -------------------------------------------------------------------

  02-Aug-2002 NJC         allocator now steps in 1MB increments, rather

			  than doubling its size each time.

			  Also, allocator_init(u_int *) now returns

			  Also, allocator_init(u32 *) now returns

			  (in the first arg) the size of the free

			  space.  This is no longer consistent with

			  using the allocator as a module, and some changes

 * On cleanup everything is released. If the list is not empty, that a

 * problem of our clients
