8fb2868c61 When user specifies the bootcode with size smaller than VTOC_BOOTCODE,
gpart_write_partcode_vtoc8 does access out of range of allocated memory.
Check size of bootcode before writing it.

pad too much when underlying GEOM object have a zero stripesize.

08892bf4bf Do not use LCM from stripesize and user specified alignment value.
When user wants have specific alignment - do what user wants.
Use stripesize as alignment value in case, when some of gpart's
arguments are ommitted for automatic calculation.

a6c21ef2d1 Use stripesize and stripeoffset in the automatic calculation of
partition offsets. If user requests specific alignment and
provider's stripesize is not zero, then use a least common multiple
from the stripesize and user specified value.
Also fix "gpart resize" implementation: do not try to align the partition
size, because the start offset may be not aligned. Instead align the
end offset and then calculate size. Also use stripesize and stripeoffset
for "gpart resize" command.

6c7e04f0f3 Some partitioning schemes want to have partitions that are aligned
with geometry. And they do recalculation of user specified parameters.
MBR, PC98, VTOC8, EBR schemes are doing that. For these schemes an
auto alignment feature (ie. gpart add -a alignment) would not work.
But it can work for GPT and BSD schemes. BSD scheme usualy is created
inside MBR, so we can use knowledge about offset of MBR partition to
calculate aligned values for BSD partitions.

Use "offset" attribute of the parent provider for better alignment.

89b172238a MFgraid/head:
Add new RAID GEOM class, that is going to replace ataraid(4) in supporting
various BIOS-based software RAIDs. Unlike ataraid(4) this implementation
does not depend on legacy ata(4) subsystem and can be used with any disk
drivers, including new CAM-based ones (ahci(4), siis(4), mvs(4), ata(4)
with `options ATA_CAM`). To make code more readable and extensible, this
implementation follows modular design, including core part and two sets
of modules, implementing support for different metadata formats and RAID
levels.

Support for such popular metadata formats is now implemented:
Intel, JMicron, NVIDIA, Promise (also used by AMD/ATI) and SiliconImage.

Such RAID levels are now supported:
RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT.

For any all of these RAID levels and metadata formats this class supports
full cycle of volume operations: reading, writing, creation, deletion,
disk removal and insertion, rebuilding, dirty shutdown detection
and resynchronization, bad sector recovery, faulty disks tracking,
hot-spare disks. For Intel and Promise formats there is support multiple
volumes per disk set.

Look graid(8) manual page for additional details.

Make `geom XXX list` and `geom XXX status` outputs more consistent:
Add -a options to print all geoms, not only ones with providers.
Add -g option for `status` to report geom's names, not provider's.
Make `status` by default report provider's status (if present), not geom's.
Make `status` report consumer's statuses, not only "synchronized" field.

e7926a3703 Reimplemented "gpart destroy -F". Now it does all work in kernel.
This was needed for recover implementation.

Implement the recover command for GPT. Now GPT will marked as
corrupt when any of three types of corruption will be detected:
1. Damaged primary GPT header or table
2. Damaged secondary GPT header or table
3. Secondary header is not located in the last LBA
Marked GPT becomes read-only. Any changes with corrupt table
are prohibited. Only "destroy" and "recover" commands are allowed.
