2398f0cd1d Hints overhaul:
- Replace some very poorly thought out API hacks that should have been
  fixed a long while ago.
- Provide some much more flexible search functions (resource_find_*())
- Use strings for storage instead of an outgrowth of the rather
  inconvenient temporary ioconf table from config().  We already had a
  fallback to using strings before malloc/vm was running anyway.

2fa72ea7d4 Fix typo: compatability -> compatibility.
Compatability is not an existing english word.

e60463deed Redo the isa compat driver shim so that each driver is self contained
and does not require that evil list of drivers in isa_compat.h.
It uses the same strategy that pci drivers use, namely a
COMPAT_ISA_DRIVER() macro that creates the glue on the fly.
Theoretically old-style isa drivers should be preloadable now.

0491a49ae7 Don't complain about not getting resources for the compatibility shim
drivers unless booted -verbose.  This cleans up the boot messages
somewhat as the old messages were confusing and not helpful for most
people.

f7b7769172 * Factor out the object system from new-bus so that it can be used by
non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
  takes about 40ns for a method dispatch on a 300Mhz PII which is only
  10ns slower than a direct function call on the same hardware.

This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.

cebf86fa3f Put a FYI in the compatability shims so that people are aware that they
are using an old unconverted driver.  Most (if not all) of the drivers
for common hardware are newbus these days.  However, we don't want
to encourage people to take the easy way out and write new drivers
using the shims.  This is just passive "encouragement".

a8f8e0bd03 GC isa_device->id_reconfig - it's not referenced anywhere anymore.
GC reconfig_isadev() - it's not used anymore.

25afb89b1c * Add struct resource_list* argument to resource_list_alloc and
resource_list_release. This removes the dependancy on the
  layout of ivars.

* Move set_resource, get_resource and delete_resource from
  isa_if.m to bus_if.m.

* Simplify driver code by providing wrappers to those methods:

     bus_set_resource(dev, type, rid, start, count);
     bus_get_resource(dev, type, rid, startp, countp);
     bus_get_resource_start(dev, type, rid);
     bus_get_resource_count(dev, type, rid);
     bus_delete_resource(dev, type, rid);

* Delete isa_get_rsrc and use bus_get_resource_start instead.

* Fix a stupid typo in isa_alloc_resource reported by Takahashi
  Yoshihiro <nyan@FreeBSD.org>.

* Print a diagnostic message if we can't assign resources to a PnP
  device.

* Change device_print_prettyname() so that it doesn't print
  "(no driver assigned)-1" for anonymous devices.

a3be63b3ce * Factor out the common code between the isa bus drivers for i386 and alpha.
* Re-work the resource allocation code to use helper functions in subr_bus.c.
* Add simple isa interface for manipulating the resource ranges which can be
  allocated and remove the code from isa_write_ivar() which was previously
  used for this purpose.

479232a2e7 GC some unused stuff relating to the old conflict checking and other lint.
Change haveseen_isadev() to something a little easier to emulate.
Store the device_t for the wrapper in isa_device.
Implement a replacement for haveseen_isadev - namely haveseen_ioport()
which takes a port size as an extra argument for a proper range check.
This (haveseen_ioport()) has not been tested, but I think it'll work.

7e381ee0b4 Back out parts of rev 1.4; making isa.c preserve the hints across a

7ceeede80c Always reset the isa hints after releasing the resources after probe,
because the act of doing the release kills the hints(!).  A quirk of
the wrapper caused it to reset all the settings, except perhaps for the
memory address. I've tested this with a real SMC 8013EPC - which uses
shared memory addresses - it seems to work OK.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.
