This commit was manufactured to restore the state of the 4.1-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Fix a bug so that we have correct number of pccard instances in pcic_attach().

o break out some of the probe routine the allocation of resources
  into an attach routine
o Recognize PnP ids
o Allocate IRQ per card rather than per system
o Better polling reporting
o Remove unneeded include files in slot.h
o store a pseudo unit number on each device we find.
o Pass a unit number to interrupt/timeout routine and use it for polling
  the hardware.

Tested on: My VAIO and with the Linksys pccard reader.

conversion to eliminate the compatability shims without making any
significant changes.  This eliminates the shim warnings.

Many ed-based Ethernet PC-cards can't get correct MAC address without
this patch.

For example, when /etc/pccard.conf had ed0 in config line, but kernel
refused this name and said

devclass_alloc_unit: ed0 already exists, using next availale unit
number

Kernel used ed1 as device name and it did not match with config and
insert/remove lines.  Fortunately, dhclient was called without args,
and it works, but if we wanted to use static IP address for PC-card,
it did not work.

This modification makes pccardd to execute insert/remove lines with
the true device name that returns from kernel.  (Last change to
etc/pccard.conf.sample eliminated all hardwired device name from
insert/remove lines in /etc/pccard.conf)

(it does not work without this fix)
