fix various typos in comments and log messages.

KNF. No functional change.

No functional change:
- Use __arraycount().
- u_int_{8,16,32}_t -> uint_{8,16,32}_t
- KNF.
- Tabify.
- Remove extra space.

branches: 1.10.18;
MD rnd.h cleanups. Please let me know if I broke anything!

branches: 1.9.2; 1.9.16;
_int*_t -> uint*_t

Same code before and after.

Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.

branches: 1.7.2; 1.7.6;
Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Mark acorn32/bus.h obsolete.

Split device_t/softc. Tested only on cs at ofisa on shark.

use device_xname()

branches: 1.4.80; 1.4.94;
merge ktrace-lwp.

branches: 1.3.2;
Use a define, rather than hard coded number, for the interrupt to claim.

Make use of the ability to parse the cs's eeprom for values, rather than
ignoring the eeprom.

Tidy up the code, add a copyright block for myself. Sprinkle a few
comments, de-_P things.

First part of support for the eb7500atx board from simtec:
http://www.simtec.co.uk/products/EB7500ATX/

also available with RISC-OS as a RiscStation:
http://www.riscstation.co.uk/html/products.html

This is basic bootstrap with support for ide and networking, currently only
tested with booting from ABLE, and not RISC-OS.

I would have placed it into evbarm, but iomd doesn't appear to use the same
interrupt files as evbarm. I'll check it into here for now, until iomd
uses the common interrupt code.
