The removal of the sparc64 support in February 2020 obsoleted the
VTOC8 partitioning scheme as no other FreeBSD platform makes use
of it. Moreover, the code is bitrotting as nothing defines e. g.
LOADER_VTOC8_SUPPORT any more and, thus, should go now, too. With
this change, the following commits are reverted as far as VTOC8
is concerned and parts haven't already previously been deleted
along with prior sparc64 removals:
094fcb157da7d366e958ba8d50d08b
The alignment example d9711c28ef
added to the VTOC8 section of gpart.8 is folded into the MBR one.
This should finally conclude the deorbit of sparc64-specific bits.

Correct the GPT example. Creation of a partition leaves free the rest
of the device (not the slice).

Fixes: ae1b731b5d Rewrite the GPT and MBR examples. For GPT, ensure that the boot partition is large enough for gptzfsboot, which has doubled in size since 10.

Traditionally the GEOM's primary channel of information from kernel to
user-space was confxml, fetched by libgeom through kern.geom.confxml
sysctl. It is convenient and informative, representing full state of
GEOM in a single XML document. But problems start to arise on systems
with hundreds of disks, where the full confxml size reaches many
megabytes, taking significant time to first write it and then parse.
This patch introduces alternative solution, allowing to fetch much
smaller XML document, subset of the full confxml, limited to 64KB and
representing only one specified geom and optionally its parents. It
uses existing GEOM control interface, extended with new "getxml" verb.
In case of any error, such as the buffer overflow, it just transparently
falls back to traditional full confxml. This patch uses the new API in
user-space GEOM tools where it is possible.

Make gctl_add_param() API public, allowing more precise control over
parameter flags. Previously it was impossible to properly declare
write-only ASCII parameters, used for result reporting, they were
declared as read-write binary instead, that was not nice.

Be explicit about it; the first mention of exFAT is for the MBR type 'ntfs',
and the reader must work back from there to the GPT type and infer that a
reference to MBR ntfs type means ms-basic-data is canonical for exFAT.
(It'd also be great if gpart had convenient aliases that did the right
thing for the partition scheme, such as 'ntfs' => ms-basic-data on GPT
schemes or 'exfat' => 'ntfs' in MBR schemes. The tool is also bad about
providing user-meaningful reasons for EINVAL failures.)
to specify an optional separator to insert before partition name;
eg if it's set to "c/", you'll get "ada0c/s1" instead of "ada0s1".
(It cannot be set to just “/“, since ada0 is a device node, not
a directory.)

GEOM is supposed to be topology-agnostic, but the GPT and BSD partition code
has arbitrary restrictions on nesting that are annoying in cases such as
running VMs on raw partitions (since the VM's partitioning scheme is not
visible to the host).
This patch adds sysctls to disable the restrictions except in the case of
BSD label (and similar) partitions with offset 0 (where we need to avoid
recursively recognizing the label).

Rather then combining hardlink creation for the geom(8) binary with
shared library build, move libraries to src/lib/geom so they are
built and installed normally. Create a common Makefile.classes
which is included by both lib/geom/Makefile and sbin/geom/Makefile
so the symlink and libraries stay in sync.
The relocation of libraries allows libraries to be build for 32-bit
compat. This also reduces the number of non-standard builds in
the system.
This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit
system out of the box as it will look in the wrong place for libraries
unless GEOM_LIBRARY_PATH is set appropriatly in the environment.
