This removes support for reading and writing volumes using the
following algorithms:
- Triple DES
- Blowfish
- MD5 HMAC integrity
In addition, this commit adds an explicit whitelist of supported
algorithms to give a better error message when an invalid or
unsupported algorithm is used by an existing volume.

The geli(8) manual page has an example for preloading keyfiles during boot.
There is no detail though on how the lookup of these variables actually
works.
Let's document that the name of a device does not have to be a part
of the variable.

This code was not actively maintained since it was introduced 10 years ago.
It lacks support for many later GEOM features, such as direct dispatch,
unmapped I/O, stripesize/stripeoffset, resize, etc. Plus it is the only
remaining use of GEOM nstart/nend request counters, used there to implement
live insertion/removal, questionable by itself. Plus, as number of people
commented, GEOM is not the best place for I/O scheduler, since it has
limited information about layers both above and below it, required for
efficient scheduling. Plus with the modern shift to SSDs there is just no
more significant need for this kind of scheduling.

Change the "count_until_fail" option of gnop, now it enables the failing
rating instead of setting them to 100%.
The original patch introduced the new flag, which sets the fail/rate to 100%
after N requests. In some cases, we don't want to have 100% of failure
probabilities. We want to start failing at some point.
For example, on the early stage, we may like to allow some read/writes requests
before having some requests delayed - when we try to mount the partition,
or when we are trying to import the pool.
Another case may be to check how scrub in ZFS will behave on different stages.
This allows us to cover more cases.
The previous behavior still may be configured.

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).

- Triple DES has been formally deprecated in Kerberos (RFC 8429)
and is soon to be deprecated in IPsec (RFC 8221).
- Blowfish is deprecated. FreeBSD doesn't support its successor
(Twofish).
- MD5 is generally considered a weak digest that has known attacks.
geli refuses to create new volumes using these algorithms via 'geli
init'. It also warns when attaching to existing volumes or creating
temporary volumes via 'geli onetime' . The plan is to fully remove
support for these algorithms in FreeBSD 13.
Note that none of these algorithms have ever been the default
algorithm used by geli(8). Users would have had to explicitly select
these algorithms when creating volumes in the past.

provider grows, GELI will expand automatically and will move the metadata
to the new location of the last sector.
This functionality is turned on by default. It can be turned off with the
-R flag, but it is not recommended - if the underlying provider grows and
automatic expansion is turned off, it won't be possible to attach this
provider again, as the metadata is no longer located in the last sector.
If the automatic expansion is turned off and the underlying provider grows,
GELI will only log a message with the previous size of the provider, so
recovery can be easier.

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>".

Allow attaching of multiple geli providers at once if they use same
passphrase and keyfiles.
This is helpful when the providers being attached are not used for boot,
and therefore the existing code to first try the cached password when
tasting the providers during boot does not apply.
Multiple providers with the same passphrase and keyfiles can be attached
at the same time during system start-up by adding the following to
rc.conf:

geli_storage_devices="ada0 ada1"

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.
