This means needing to be careful about buffers and keeping track
of external read request length.

Note: currently 'mkver' script is using hardcoded knowledge and always
emits -a in the version string, a more through solution would be to generate
the script with something that we own.
Rewrite rm_r to use *at function, allowing to remove home directories along with

This allows to simplify the code a bit for -R by not having to keep modifying

While here, add regression tests for the functionality
time between ntp_adjtime() clock offset adjustments. This eliminates spurious
frequency steering after a large clock step (such as a 1970->2015 step on a
system with no battery-backed clock hardware).
This problem was discovered after the import of ntpd 4.2.8, which does things
in a slightly different (but still correct) order than the 4.2.4 we had
previously. In particular, 4.2.4 would step the clock then immediately after
use ntp_adjtime() to set the frequency and offset to zero, which captured the
post-step time-of-day as a side effect. In 4.2.8, ntpd sets frequency and
offset to zero before any initial clock step, capturing the time as 1970-ish,
then when it next calls ntp_adjtime() it's with a non-zero offset measurement.
This non-zero value gets multiplied by the apparent 45-year interval, which
blows up into a completely bogus frequency steer. That gets clamped to
500ppm, but that's still enough to make the clock drift so fast that ntpd has
to keep stepping it every few minutes to compensate.
- Tweek man page.
- Remove all mention of RANDOM_FORTUNA. If the system owner wants YARROW or DUMMY, they ask for it, otherwise they get FORTUNA.
- Tidy up headers a bit.
- Tidy up declarations a bit.
- Make static in a couple of places where needed.
- Move Yarrow/Fortuna SYSINIT/SYSUNINIT to randomdev.c, moving us towards a single file where the algorithm context is used.
- Get rid of random_*_process_buffer() functions. They were only used in one place each, and are better subsumed into those places.
- Remove *_post_read() functions as they are stubs everywhere.
- Assert against buffer size illegalities.
- Clean up some silly code in the randomdev_read() routine.
- Make the harvesting more consistent.
- Make some requested argument name changes.
- Tidy up and clarify a few comments.
- Make some requested comment changes.
- Make some requested macro changes.
* NOTE: the thing calling itself a 'unit test' is not yet a proper
unit test, but it helps me ensure things work. It may be a proper
unit test at some time in the future, but for now please don't make
any assumptions or hold any expectations.

CloudABI does not provide an explicit kill() system call, for the reason
that there is no access to the global process namespace. Instead, it
offers a raise() system call that can at least be used to terminate the
process abnormally.
CloudABI does not support installing signal handlers. CloudABI's raise()
system call should behave as if the default policy is set up. Call into
kern_sigaction(SIG_DFL) before calling sys_kill() to force this.

Previously vputx would detect the condition and clear the flag.
With this change it is invalid to have both v_usecount > 0 and the flag
set. Assert the condition is met in all revlevant places.

Previously several places were doing it on its own, partially
incorrectly (e.g. without the filedesc locked) or even actively harmful
