f5b4099e6b geom: don't write stack garbage in disk labels
Most consumers of g_metadata_store were passing in partially unallocated
memory, resulting in stack garbage being written to disk labels. Fix them by
zeroing the memory first.

gvirstor repeated the same mistake, but in the kernel.

Also, glabel's label contained a fixed-size string that wasn't
initialized to zero.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

b5dc98c049 Fix alignment of 'last' in autofill.
'last' is the sector number of the last usable sector. Sector
numbers start with 0. As such, 'last' is always 1 less than
the count of sectors and aligning 'last' down as-is means that
the number of free sectors is pessimized by 'alignment - 1' if
the number of usable sectors was already a multiple of the
alignment. Consequently, gpart(8) failed to create a partition
when the alignment and size were such that it would extend to
the end of the disk.

37eb5966f9 Provide an articulate example of how to properly delete partitions and
partitioning scheme.

Users often get confused and frustrated when trying to delete partition
table and getting ``Device busy'' error because they forgot (or did not
ever know that they have) to delete all its partitions first, and while
the manual page mentions this briefly, it does not stress it out enough.

graid3, gshsec, gstripe, and geom_virstor).

Before this change it was impossible to set number of PKCS#5v2 iterations,
required to set passphrase, if it has two keys and never had any passphrase.
Due to present metadata format limitations there are still cases when number
of iterations can not be changed, but now it works in cases when it can.

d873662594 Create the GELIBOOT GEOM_ELI flag
This flag indicates that the user wishes to use the GELIBOOT feature to boot from a fully encrypted root file system.
Currently, GELIBOOT does not support key files, and in the future when it does, they will be loaded differently.
Due to the design of GELI, and the desire for secrecy, the GELI metadata does not know if key files are used or not, it just adds the key material (if any) to the HMAC before the optional passphrase, so there is no way to tell if a GELI partition requires key files or not.

Since the GELIBOOT code in boot2 and the loader does not support keys, they will now only attempt to attach if this flag is set. This will stop GELIBOOT from prompting for passwords to GELIs that it cannot decrypt, disrupting the boot process

46e3447026 Enable BIO_DELETE passthru in GELI, so TRIM/UNMAP can work as expected when
GELI is used on a SSD or inside virtual machine, so that guest can tell
host that it is no longer using some of the storage.

Enabling BIO_DELETE passthru comes with a small security consequence - an
attacker can tell how much space is being really used on encrypted device and
has less data no analyse then. This is why the -T option can be given to the
init subcommand to turn off this behaviour and -t/T options for the configure
subcommand can be used to adjust this setting later.
