Device paths encoded into the FILEPATH_DEVICE_PATH are UCS2 not
ASCII/UTF8. Convert to utf8 and print that when printing File
paths. Also, since File may be at the end of a long device path,
output File() around the path so it doesn't just show up as random
nodes that might accidentally match real node paths names and cause
errors.

The default value for arc_no_grow_shift may not be optimal when using
several GiB ARC. Expose it via sysctl allows users to tune it easily.
Also expose arc_grow_retry via sysctl for the same reason. The default value of
60s might, in case of intensive load, be too long.

This driver supports both NTB-to-NTB and NTB-to-Root Port modes (though
the second with predictable complications on hot-plug and reboot events).
I tested it with PEX 8717 and PEX 8733 chips, but expect it should work
with many other compatible ones too. It supports up to two NT bridges
per chip, each of which can have up to 2 64-bit or 4 32-bit memory windows,
6 or 12 scratchpad registers and 16 doorbells. There are also 4 DMA engines
in those chips, but they are not yet supported.
While there, rename Intel NTB driver from generic ntb_hw(4) to more specific
ntb_hw_intel(4), so now it is on par with this new ntb_hw_plx(4) driver and
alike to Linux naming.

In particular, the switch statement on the type of dynamic entries
in _rtld_relocate_nonplt_self() needs to not use a jump table since

In particular, MIPS now has COMPAT_FREEBSD32 for n64 kernels so this
cannot be ignored for n64. On the other hand, it is unneeded for o32
MIPS kernels as the issue is only present when using 64-bit registers,
so remove the workaround from o32 kernels.

Now that all of the packaged software has been adjusted to either use
Flower (https://github.com/NuxiNL/flower) for making incoming/outgoing
network connections or can have connections injected, there is no longer
need to keep accept() around. It is now a lot easier to write networked
services that are address family independent, dual-stack, testable, etc.
Remove all of the bits related to accept(), but also to

illumos 4185 ("add new cryptographic checksums to ZFS: SHA-512,

without adding support for skein, sha512 and edonr on FreeBSD.
Support for skein and sha512 was added later on, but edonr is still not
implemented in FreeBSD.
Prior to this commit zfs(8) correctly rejected edonr, but with an error

This patch changes the way XPT_GDEV_TYPE works for NVMe. The current
ccb_getdev structure includes pointers to the NVMe Identify Controller
and Namespace structures, but these are kernel virtual addresses which
are not accessible from user space.
As an alternative, the patch changes the pointers into padding in
ccb_getdev and adds two new types to ccb_dev_advinfo to retrieve the
Identify Controller (CDAI_TYPE_NVME_CNTRL) and Namespace
(CDAI_TYPE_NVME_NS) data structures.
