Previously, we only validated names for character restrictions. This is
helpful, but we should've also checked length restrictions- dataset names
must be restricted to MAXNAMELEN.
While here, move validation before doing a bunch of concatenations and fix
error handling in be_rename. It was previously setting the error state based
on return value from a libzfs function, which is wrong: libzfs errors don't
necessarily match cleanly to libbe errors. This would cause the assertion in
be_error to hit when the error was printed.
jails since FreeBSD 7.
Along with the system call, put the various security.jail.allow_foo and
security.jail.foo_allowed sysctls partly under COMPAT_FREEBSD11 (or
BURN_BRIDGES). These sysctls had two disparate uses: on the system side,
they were global permissions for jails created via jail(2) which lacked
fine-grained permission controls; inside a jail, they're read-only
descriptions of what the current jail is allowed to do. The first use
is obsolete along with jail(2), but keep them for the second-read-only use.

The fix is only partial and causes an asymmetry which breaks a test in
multi_test.sh.
We should consider both parts of the issue found in OpenBSD[1], but for now
just revert the change.

lld should now be a usable linker for armv7, and is already used as the
bootstrap linker (for linking the kernel and userland). Also enable as
the system linker now (/usr/bin/ld) for further testing and evaluation.
(This change will be reverted in case of unexpected fallout.)

This fixes the build and I will redo these changes as part of a future review

BD_SUPPORT_FRAGS is preprocessor knob to allow partial reads in bioscd/biosdisk
level. However, we already have support for partial reads in bcache, and there
is no need to have duplication via preprocessor controls.
Note that bioscd/biosdisk interface is assumed to perform IO in 512B blocks,
so the only translation we have to do is 512 <-> native block size.

ZoL did the same mistake, and fixed it with separate commit 863522b1f9:
dsl_scan_scrub_cb: don't double-account non-embedded blocks
We were doing count_block() twice inside this function, once
unconditionally at the beginning (intended to catch the embedded block
case) and once near the end after processing the block.
The double-accounting caused the "zpool scrub" progress statistics in
"zpool status" to climb from 0% to 200% instead of 0% to 100%, and
showed double the I/O rate it was actually seeing.
This was apparently a regression introduced in commit 00c405b4b5e8,
which was an incorrect port of this OpenZFS commit:

While we're not super size constrained, the x86 BIOS /boot/loader has
to be less than about 520k-530k to be reliable. The LUA loader is at
this size today. -Oz saves 15-20% on the size, keeping us safely small
enough (comparable to where we were with the 4th loader). This will
also help with sjg's work on bringing in bearssl, though we may again
be looking for space in the LUA loader.

This is actually several different bugs:
- The code is not designed to handle inpcb deletion after interface deletion
- add reference for inpcb membership
- The multicast address has to be removed from interface lists when the refcount
goes to zero OR when the interface goes away
- decouple list disconnect from refcount (v6 only for now)
- ifmultiaddr can exist past being on interface lists
- add flag for tracking whether or not it's enqueued
- deferring freeing moptions makes the incpb cleanup code simpler but opens the
door wider still to races
- call inp_gcmoptions synchronously after dropping the the inpcb lock
Fundamentally multicast needs a rewrite - but keep applying band-aids for now.

So that I don't have to keep grepping around the codebase to remember what each
