When generating timestamp based GUIDs for reproducable builds
- increment timestamp by 100ns for each partition.
- use the standard time-based UUID format (type 1) and don't
  pretend it's a random number (type 4).
- make the -T option actually work for the uuid command.

gpt(8): Make gpt type array and enum match again.

Add cross-referencing comment to reduce the probability of these
getting out of sync again.

Should fix a slew of failing tests since kre's recent change to add
windows-recovery to the array but not to the enum:

sbin/gpt/t_gpt:create_2part
sbin/gpt/t_gpt:migrate_disklabel
sbin/gpt/t_gpt:recover_backup
sbin/gpt/t_gpt:recover_primary
sbin/gpt/t_gpt:remove_2part
sbin/gpt/t_gpt:resize_2part
sbin/gpt/t_gpt:restore_2part

Recognise Windows Recovery partitions.

Mostly merge changes from HEAD upto 20200411

Merge changes from current as of 20200406

Now that we use the same UUID for ZFS as FreeBSD, drop the FreeBSD marker
from the description.

adjust gpt_uuid_generate() to accept gpt==NULL

Sync with HEAD

Sync with HEAD, resolve a few conflicts

Add a query function (for external code) to enumerate the know guids.
Add recently added VMware GUIDs to the internal enum type.
Fix some short names (bogus + duplicate).

Sync with HEAD, resolve a couple of conflicts

add support to detect the 3 vmware GPT partition types:

- VMKcore (dump partition)
- VMFS
- VMware reserved

this enables vmkcore partitions for netbsd swap or dump, as well
as naming all of them.

Many changes including:
- Significant refactoring
- PR/51230: Add the ability to set the active flag in the PMBR
- Let individual commands decide if ioctl(DIOCMWEDGES) should be done
- Add a "header" subcommand that displays information about the size of
  the disk along with information from the GPT header if it exists
- Add listing commands for type, set and unset
- Add help and formatting for set and unset
- Change show to print all the attribute info in one line.
- Improve documentation, including booting and exit status
- Check device parameter to avoid segfaults

- record the sector size of the disk
- correct confusion with end_cylinder and end_sector in MBRs
--
- dump all partitions, not just ones that are in use
- while here, squash a memory leak
     It shouldn't be necessary to backup unused partitions, however
the partition GUID is created at the time the GPT is created and
is never changed.  It shouldn't matter if the GUID of an unused
partition changes, but there may be some special case where it
does.  Since it isn't a big deal to record the unused partitions,
might as well do it.
--
Initial cut of gpt restore.  This functions correctly in testing,
but isn't all that pretty.  It has minimal error testing and may
leak memory.  It also only works with empty disks.  If passed "-F"
flag, it will blank the disk for you.
--
document the new restore subcommand
--
- make gpt_gpt() available for use directly by subcommands
- create new resizedisk disk subcommand for relocating backup GPT
--
Fix compile error observed on i386. Use PRIu64.
--
no C99isms in tool code
--
- handle a GPT that isn't an exact multiple of a sector
- adjust PMBR size, in case new disk is a different size
- don't leak as much memory
- clean up error handling somewhat

Check size of correct buffer.  Note, just being pedantic as the buffer

Don't needlessly leak your date/time and MAC address when you edit

Read from /dev/urandom rather than calling arc4random or anything,
since this is a tool.  (Cygwin seems to have /dev/urandom, but yell
if this breaks the build on your exotic platform because it lacks
/dev/urandom.)

Match any type, when no option is given, just like for the label command.

Factor out the getdisksize() drvctl method, and provide an alternative that
directly uses the disk ioctl's instead of relying on the drvctl device driver
which is currently not mandatory.
