the Intel 82371AB PCI-ISA bridge. We now do this all the time for the
!APIC case in the atpic driver. This cuts the raw line count for this
driver by about 40%.

- Factor out code common to all ISA bridge drivers attach methods into a
isab_attach() function.
- Rename the PCI-ISA bridge driver's attach function to pci_isab_attach()
and have it call isab_attach().
across system suspends on the Intel 82371AB PCI-ISA bridge. On a
Sony Vaio C1XD that I have, these registers are not set correctly
after an ACPI resume. The result is that after resuming, a shared
IRQ is left in edge-triggered mode so the interrupt can later become
jammed in a state where the line remains asserted, but the handler
is never called.

the ISA bus.
- Don't expect that a PCI:ISA bridge will have a correct class value;
if we're checking PCI IDs, only depend on these.
This should fix the loss of ISA on machines with PCI:EISA bridges like the
AS4100.
class/subclass, so give up trying to cull the list. Instead, complain
in the bootverbose case, but otherwise just accept that we will have to
carry this list of device IDs around.
- Improve the formatting for devices identified by the database.
- Fix the pcib_route_interrupt method definition, as an old version
snuck in here somehow 8(
- Remove a couple of the vendor/device IDs for PCI:ISA bridges which
correctly identify themselves.

- Move PCI core code to dev/pci.
- Split bridge code out into separate modules.
- Remove the descriptive strings from the bridge drivers. If you
want to know what a device is, use pciconf. Add support for
broadly identifying devices based on class/subclass, and for
parsing a preloaded device identification database so that if
you want to waste the memory, you can identify *anything* we know
about.
- Remove machine-dependant code from the core PCI code. APIC interrupt
mapping is performed by shadowing the intline register in machine-
dependant code.
- Bring interrupt routing support to the Alpha
(although many platforms don't yet support routing or mapping
interrupts entirely correctly). This resulted in spamming
<sys/bus.h> into more places than it really should have gone.
- Put sys/dev on the kernel/modules include path. This avoids
having to change *all* the pci*.h includes.
