Apply some fixes post rS336659, which allowed multiple provders to be
initialized in a single command.
- Fix issue where second and subsequent providers would fail init.
This was due to the metadata struct being zeroed after the first
provider init was completed, despite containing common data required
for subsequent providers.
- Fix issue where -B "none" would still result in the metadata being
backed-up if multiple providers had been specified. This was due to
the backupfile of "none" being incorrectly made unique for each
provider by appending "-<prov>".

Some paths through be_exists will set the error state, others will not
There are multiple reasons that a call can fail, so clean it up a bit: all
paths now return an appropriate error code so the caller can attempt to
distinguish between a BE legitimately not existing and just having the wrong
mountpoint. The caller is expected to bubble the error through to the
internal error handler as needed.
This fixes some unfriendliness with bectl(8)'s activate subcommand, where
it might fail due to a bad mountpoint but the only message output is a
generic "failed to activate" message.

For users who have a seperate zfs mount of /usr or /usr/lib, this will
cause dynamic loading failures when attempting to execute zfs mount on
bootup. E.g. the system won't boot.
Including <src.opts.mk> sets SHLIBDIR, so SHLIBDIR?= has no
effect. The other lib/ Makefiles solve this problem by moving the
SHLIBDIR assignment to before .include <src.opts.mk>.

vermaden (maintainer of beadm) points out the following inconsistencies:
- "missing command" is not printed prior to usage if the error is simply a
missing command; this should be obvious from the context
- "bectl rename" isn't using the "don't unmount" flag (zfs rename -u), so
the active BE can't be renamed. It doesn't make sense in our context to
*not* use -u, so use it.
Documentation updates reflect the above and note an inconsistency with the
'destroy' command that is consistent with other parts of the base system.
A fix for libbe(3) not properly being installed to /lib is included.
SHLIBDIR should have been added when it was moved in r337995.

This fixes building libmd on MacOS/Linux. The real fix is probably to
build it as a .S file with $CC instead. It might also be better to just
compile the C file in userspace since the compiler can the use SSE/AVX.

The current invocation of unifdef causes the build to fail when using a shell
with -o pipefail on by default since unifdef will return a non-zero exit status
if it changes something. The only thing this call to unifdef does is remove 5
lines that will be ignored by the compiler anyway. Furthermore, it is the only
make rule in the source tree that requires unifdef. Removing this call also
makes it slightly easier to build without inhering $PATH (D16815) since we
don't need unifdef anymore.
I also noticed that the sed call to replace the include guard has been broken
for over 10 years since the import of expat 2.0.1 changed it from
`XmlParse_INCLUDED` to `Expat_INCLUDED`. I could also fix this but since it's
been broken for so long and no one noticed, it's probably not necessary.

This will only work if the caller already handles SIGSYS, which is not
always the case.
Address this by checking osreldate instead. Note that because there
was not __FreeBSD_version bump when the system call was added, use

the system call.

Some background: in the GSoC project, libbe/Makefile lived in lib/libbe. I
created projects/bectl branch, maintained the above for all of five
minutes before I misread Makefile.inc1 and decided that it couldn't possibly
build outside of cddl/, so I kicked the Makefile out into the cddl/ build
and all was good. The misreading was of the bit where .WAIT is added to
SUBDIR after lib, libexec but prior to building bin and cddl *only during
the install targets*, which is the critical part.
Fast forward- buildworld was still broken in my branch unbeknownst to me
because I didn't nuke my OBJDIR. Combing through Makefile.inc1 eventually
revealed the necessary magic to make sure that libbe's dependencies are
specified well enough, and it becomes clear what needs done to make a
non-cddl/ build work. This is an interesting prospect, because the build
split is kind of annoying to work with.
IGNORE_PRAGMA is added to avoid dropping WARNS by one more. This was
previously pulled in via cddl/Makefile.inc.
This basically adds makes use of the C99 restrict keyword, and also
adds some 'const's to four threading functions: pthread_mutexattr_gettype(),
pthread_mutexattr_getprioceiling(), pthread_mutexattr_getprotocol(), and
pthread_mutex_getprioceiling. The changes are in accordance to POSIX/SUSv4-2018.

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.

Along with the system call, put the various security.jail.allow_foo and

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.
