imp 899856ecd8 Big cleanup of resource code for pccard. Once coventry noticed
problems here, it became clear we were being too complex.

o Don't keep track of resources in two places
o Use resource_list_purge instead of rolling our own
o Just reassign the ownership of the resource, rather than freeing it
  and reallocating it.
o Fix compile problems when sizeof(u_long) != sizeof(int)
