The NVMe specification has no ability to specify a maximum delete size
that is less than the full capacity of the namespace - so just using the
namespace size is the correct value here.
This fixes reported issues where ZFS trim on init looked like it was
hanging the system - previously the default I/O max size (128KB on
Intel NVMe controllers) was used for delete operations which worked out
to only about 8MB/s. With this patch I can add an 800GB DC P3700
drive to a ZFS pool in about 15-20 seconds.

This feature is inspired by another Unix-alike OS commonly found on
airplane headrests.
A number of beasties[0] are drawn at top of framebuffer during boot,
based on the number of active SMP CPUs[1]. Console buffer output
continues to scroll in the screen area below beastie(s)[2].
After some time[3] has passed, the beasties are erased leaving the
entire terminal for use.
Includes two 80x80 vga16 beastie graphics and an 80x80 vga16 orb
graphic. (The graphics are RLE compressed to save some space -- 3x 3200
bytes uncompressed, or 4208 compressed.)
[0]: The user may select the style of beastie with
kern.vt.splash_cpu_style=(0|1|2)
[1]: Or the number may be overridden with tunable kern.vt.splash_ncpu.

1) Use the TX FIFO empty interrupts to poll the transmit FIFO usage,
instead of using own software counters and waiting for SOF
interrupts. Assume that enough FIFO space is available to execute one
USB OUT transfer of any kind when the TX FIFO is empty.
2) Use the host channel halted event to asynchronously wait for host
channels to be disabled instead of waiting for SOF interrupts. This
results in less turnaround time for re-using host channels and at the
same time increases the performance.
The network transmit performance measured by "iperf" for the "RPi-B v1
2011/12" board, increased from 45MBit/s to 65Mbit/s after applying the
changes above.

The random_get() system call works similar to getentropy()/getrandom()
on OpenBSD/Linux. It fills a buffer with random data.
This change introduces a new function, read_random_uio(), that is used
to implement read() on the random devices. We can call into this
function from within the CloudABI compatibility layer.

not. When doing multiqueue, we are all setup to have full 32bit RSS hash from
the card. We do not need to hide that under "ifdef RSS" and should expose that
by default so others like lagg(4) can use that and avoid hashing the traffic by
themselves.
While here, delete the FreeBSD version check and use of deprecated M_FLOWID.

- 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.

and brings in the following:
- fix zerocopy monitor ports and introduce copying monitor ports
(the latter are lower performance but give access to all traffic
in parallel with the application)
- exclusive open mode, useful to implement solutions that recover
from crashes of the main netmap client (suggested by Patrick Kelsey)
- revised memory allocator in preparation for the 'passthrough mode'
(ptnetmap) recently presented at bsdcan. ptnetmap is described in
