6f493e311f libbe(3): Check that dataset is to be mounted at / for be_exists
This makes the be_exists behavior match the comments that assert that we've
already checked that the dataset derived from the BE name is set to mount at
/.

Other changes of note:
- bectl_list sees another change; changing mountpoint based on mount status
  turns out to be a bad idea, so instead make the mounted property of the
  returned nvlist the path that it's mounted at

- Always return the "mountpoint" property in "mountpoint" if it's ste

c3bcd31273 bectl(8): Only show mountpoint if the dataset is actually mounted
This is to accomodate a later change in libbe(3) that will always return the
mountpoint, whether it be the directory the dataset is actively mounted at
or the "mountpoint" property.

1dd8b253d3 libbe(3): Rewrite activate temp bits to rely less on loader
Loader is still relied upon at the beginning of libbe to specify the be
root, but we can derive from that the primary zpool and any vdevs that we
need to set nextboot bits on.

This lets me successfully `bectl activate -t test`, but UEFI loader doesn't
quite yet understand so it's effectively defunct.

b6064a8535 bectl(8): bectl jail improvements
- Support passing arbitrary jail arguments via -o
- Split the related (and rewritten since the GSoC) jail bits out into a new
  bectl_jail.c file, to reduce clutter in bectl.c
- Don't use RFC 1918 IP space [0]; we'll instead set no default IPv4 and let
  the user pass in any address options they wish via -o

5ef81a6b77 bectl(8): Implement bectl list -s
be_get_dataset_snapshots has been added to libbe(3), effectively returning
the same information as be_get_bootenv_props but for snapshots of the given
dataset. The assumption is that one will have the BE dataset name before
wanting to grab snapshots.

411563c444 bectl: Implement -D ("space if origin datasets were deleted")
This also accomplishes the following:

- Proxy through zfs_nicenum as be_nicenum, because it looks better than
  humanize_number and would presumably be useful to other libbe consumers.

- Rename be_get_snapshot_props to be_get_dataset_props, make it more useful

05fd3946e6 bectl(8): Take -H parameter to list into account
-H is for a scripted format, where all fields are tab-delimited and the
headers go away. We accomplish this by splitting out pad printing to a
separate function that'll take into account whether we're supposed to be
scripted or not.

This has the nice side effect of maintaining positive column sizes again.

2e9b90de37 bectl(8): Sort BEs lightly by active (now or later) BE, then others
While it could be preferred to do this at insert in libbe(3), there's no
convenient way to insert at the head of an nvlist. Instead, we'll make two
passes over- once to print anything active either now or at nextboot, and
another to print everything else.

This doesn't actually impact performance in a significant way here, so we'll
worry about further optimizations if the need actually arises.

45778557a3 bectl(8): Add some relevant bectl list -a information
bectl list -a should show the boot environment, its relevant dataset, and
the snapshot it was created from. The header also changes to indicate the
rough order in which these things will show.

While here, start doing a little bit of spring cleaning and splitting
different bits out.

sanity-check that there's actually a BE mounted at the requested jail root
before invoking jail_remove(2).

At a bare minimum, this function will return 0 if a BE is mounted at the
given path or non-zero otherwise.  If the optional 'details' nvlist is
supplied, it is filled with an nvpair containing just the information about
the BE mounted at the path.  This nvpair is structured just as it is for
be_get_bootenv_props, except limited to just the single mount point.

0d52b2932a libbe(3): Find rootfs instead by enumerating child datasets of BE root
This makes us more resilient to a rename of the bootfs, but still wouldn't
withstand pool renames or guid renames. More importantly, this allows `bectl
create <foo>` work out of the box to create a boot environment based on the
currently booted one.

8992c584ea libbe(3): Disambiguate 'active' a little bit, add 'bootfs'
- Rename 'active' to 'rootfs', which is used in other places to describe the
currently booted (or about to be booted) BE.

- Add 'bootfs', which indicates the next boot environment to be booted. This
  is pulled from the BOOTFS zpool property.

- Go ahead and keep an open handle to the active zpool. We might need to
  enumerate datasets, get properties, and set properties (e.g. bootfs)
  throughout other libbe bits, and a single handle isn't overly expensive.

7a13690726 In C remquol() and thus also in C remainderl(), don't clobber the sign bit
of NaNs before possible returning a NaN.

The remquo*() and remainder*() functions should now give bitwise identical
results across arches and implementations, and bitwise consistent results
(with lower precisions having truncated mantissas) across precisions.  x86
already had consistency across amd64 and i386 and precisions by using the
i387 consistently and normally not using the C versions.  Inconsistencies
for C reqmquol() were first detected on sparc64.

Remove double second clearing of the sign bit and extra blank lines.

bd51dee28c Fix the conversion to use nan_mix() in r336362. fmod*(x, y),
remainder*(x, y) and remquo*(x, y, quo) were broken for y = 0 by changing
multiplication by y to addition of y.  (When y is 0, the result should be
NaN but became 1 for finite x.)

Use a new macro nan_mix_op() to give more control over the mixing, and
expand comments.

Recent re-testing missed finding this bug since I only tested the macro
version on amd64 and i386 and these arches don't use the C versions (they
use either asm versions or builtins).

408338cba2 Deprecate jedec_ts(4) and point users to jedec_dimm(4) instead
jedec_dimm(4) is a superset of the functionality of jedec_ts(4). Mark
jedec_ts(4) as removed in FreeBSD 12, and include a pointer to the migration
instructions in the jedec_dimm(4) manpage, in both the jedec_ts(4) code and
the jedec_ts(4) manpage. Add a note to the jedec_dimm(4) manpage about the
fact that it is a superset of jedec_ts(4).

This change will be MFCed to stable/11 and stable/10; the followup change
to actually remove jedec_ts(4) from -HEAD will not.
