80513cb5ae o Make usage of /dev/random dependant on 
pseudo-device   rnd                     # /dev/random and in-kernel generator
  in config files.

o Add declaration to all architectures.

o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
  that this code is derived in part from Ted Tyso's linux code.

6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices 
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

3b4e2a1ac9 In wdattach(), when printing out info about the drive, make the output 
look a little more like a SCSI disk's.  This has the pleasant side-effect
of preventing the output from annoyingly extending past 80 columns.

2a73ef60b7 change cfprint_t type definition to take a const char *, rather than 
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

de7c200585 New device attachment scheme: 
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  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.

3a7bbb1acd lip service to making ISA support machine-independent. This is the first 
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.  eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.
