79e0a8a2b9 update for addition of a machine-dependent cookie as the first argument 
to isa_intr_{,dis}establish().

8f40bb43a8 add an isa_attach_hook() function which currently does nothing, and update 
isa_intr_establish() and isa_intr_disestablish() to take an opaque cookie
as their (new) first argument.

f3b97d1287 prototype MD functions for use by MI ISA code (isa_attach_hook(), 
isa_intr_{,dis}establish()) here.  Make this file safely includable by
<dev/isa/isavar.h> and by all of the places in the i386 that are currently
including it, which means multiple inclusion protection and a few
otherwise-extraneous 'forward' structure declarations.  isa_intr_establish()
and isa_intr_disestablish() now take as their first argument a
machine-dependent cookie of type isa_chipset_tag_t, which is also defined
here.

	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

5b39541e48 New generic disk framework. Highlights: 
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.
