thorpej 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.

/*
* CS/80 partitions. We reserve the first cylinder for a LIF
* style boot directory (the 8k allowed in the BSD filesystem
* is just way too small). This boot area is outside of all but
* the C partition. This implies that you cannot use the C
* partition on a bootable disk since the filesystem would overlay
* the boot area. You must use the A partition.
*
* These maps support four basic layouts:
*
* A/B/G: This is the "traditional" setup for a bootable disk.
* A is the root partition, B the swap, and G a user partition.
* A/D/H: This is a setup for bootable systems requiring more swap
* (e.g. those who use HPCL). It has A as the root, D as a
* larger swap, and H as a smaller user partition.
* A/D/E/F: Similar to A/D/H with E and F breaking H into two partitions.
* E could be used for /usr and F for users.
* C: This gives a single, non-bootable, large user filesystem.
* Good for second drives on a machine (e.g. /usr/src).
