Add resource activation routines to pcic driver. Minor cleanup of socket attach code. We now have at least a chance for pccard devices appearing in the future. This is a snapshot of ongoing work. Proceed at your own risk.

# Companion interface for pccard. We need to set attributes for memory
# and i/o port mappings (as well as other types of attributes) that have
# a well defined meaning inside the pccard/cardbus system. The bus
# methods are inadequate for this because this must be done at the time the
# resources are set for the device, which predates their activation. Also,
# the driver activating the resources doesn't necessarily know or need to know
# these attributes.

checkpoint latest pccard/pcic hacking: o Eliminate cross calls between the devices. Instead move to using the newbus messaging system. Added three new card calls: attach_card, detach_card, get_type. o Eliminate interrupt routine in pccard we never use. o Move from deactivate to detach for removing cards. o Start mapping CIS memory, but it is broken and causes panics. At least it is closer to working than before. o Eliminate struct device everywhere. It was bogus. o Initialize softc for pccard device so we have valid pointers to ourselves. o Implement routine to find the pcic ivar for a child device of the pccard so we can use it to talk to the pcic hardware. o Lots of minor tiding up. This version now panics when we try to read the CIS. The next batch of work to make this work is what was outlined in my posting to mobile about resource allocation and such.

Implement indirection in the pccard probe/attach. This should make it possible to have different probe/attach semantics between the two systems and yet still use the same driver for both. Compatibility methods for OLDCARD drivers. We use these routines to make it possible to call the OLDCARD driver's probe routine in the context that it expects. For OLDCARD these are implemented as pass throughs to the device_{probe,attach} routines. For NEWCARD they are implemented such such that probe becomes strictly a matching routine and attach does both the old probe and old attach. compat devices should use the following: /* Device interface */ DEVMETHOD(device_probe), pccard_compat_probe), DEVMETHOD(device_attach), pccard_compat_attach), /* Card interface */ DEVMETHOD(card_compat_match, foo_match), /* newly written */ DEVMETHOD(card_compat_probe, foo_probe), /* old probe */ DEVMETHOD(card_compat_attach, foo_attach), /* old attach */ This will allow a single driver binary image to be used for both OLDCARD and NEWCARD. Drivers wishing to not retain OLDCARD compatibility needn't do this. ep driver minorly updated. sn driver updated more than minorly. Add module dependencies to allow module to load. Also change name to if_sn. Add some debugging code. attempt to fix the cannot allocate memory problem I'd been seeing. Minor formatting nits.
