Make NdisReadPcmciaAttributeMemory() and NdisWritePcmciaAttributeMemory()

actually work.

Make the PCI and PCCARD attachments provide a bus_get_resource_list()
method so that resource listing for PCCARD works. PCCARD does not
have a bus_get_resource_list() method (yet), so I faked up the
resource list management in if_ndis_pccard.c, and added
bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c.
The one in the PCI attechment just hands off to the PCI bus code.
The difference is transparent to the NDIS resource handler code.

Fixed ndis_open_file() so that opening files which live on NFS
filesystems work: pass an actual ucred structure to VOP_GETATTR()
(NFS explodes if the ucred structure is NOCRED).

Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory
resources correctly.

Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export
it so that if_ndis_pccard.c can use it, and junk the other copy
of my_strcasecmp() from if_ndis_pccard.c.
