7978f67e28 I think I need to move the newly static variables to the random_state
structure; remind myself in the cooments. Also regroup all the Yarrow
variables at the top of the variable list; they are "special".
(no functional change).

87a478de7b One should never allocate 4-kilobyte structs and such on the interrupt
stack.  It's bad for your machine's health.

Make the two huge structs in reseed() static to prevent crashes.  This
is the bug that people have been running into and panic()ing on for the
past few days.

fb15ada363 Provide more splsofttq() protection for the reseed task (running out of
taskqueue_swi).

43975bd56c Make sure that tasks (running out of taskqueue_swi at splsofttq)
are not interfered with by the harvester.

585ebe2b41 Yarrow tweaks; separate the fast and slow reseed tasks so that they don't
stomp on each other; provide constant names (as enums) for the harvester
to use (makes it more self-documenting).

c9ec235ca1 Add entropy gathering code. This will work whether the module is
compiled in or loaded.

d44f401738 Staticize a variable.
This fixes the case where linking randomdev into the kernel statically
can cause panics at shutdown time.

1f67cd8737 I am guilty of an act of ommission. There is no longer a /dev/urandom
device with Yarrow, and although I coded for that in dev/MAKEDEV, I forgot
to _tell_ folks.

This commit adds back the /dev/urandom device (as a duplicate) of /dev/random,
until such time as it can be properly announced.

This will help the openssl users quite a lot.

d4262fb0dd style(9) fixes from BDE.
We shouldn't use '#include ""', rather '#include<>'.

4db9ae91ff New machine-independant /dev/random driver.
This is work-in-progress, and the entropy-gathering routines are not
yet present. As such, this should be viewed as a pretty reasonable
PRNG with _ABSOLUTELY_NO_ security!!

Entropy gathering will be the subject of ongoing work.

This is written as a module, and as such is unloadable, but there is
no refcounting done. I would like to use something like device_busy(9)
to achieve this (eventually).

Lots of useful ideas from:	bde, phk, Jeroen van Gelderen
