Sync with HEAD

Mostly merge changes from HEAD upto 20200411

allocate buffer for disk I/O via geteblk() instead of malloc(), so they
are properly aligned; e.g. readdisklabel() does the same

also removed the DKW_MALLOC()/DKW_FREE()/DKW_REALLOC() macros as apparently
unnecessary, these files don't seem to be compiled into any userland tools

dkwedge_gpt.c confirmed working, others compile-tested only

Merge changes from current as of 20200406

Teach dk(4) about ZFS.

"looks ok" mlelstv

Fix info leak: always clear 'dkw', because some of its (otherwise
uninitialized) fields can be copied to userland, typically in the
DIOCGWEDGEINFO ioctl.

Fix buffer overflow. Triggerable by plugging a specially-crafted USB key
in the machine (the kernel automatically tries to parse its GPT header).
The check could maybe be appeased to allow bigger sizes, but we've never
done that, so I'm leaving it as-is.

add types for windows and linux partitions.

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.

Quadruple GPT partition entry count limit (to 512 entries or 64KiB).

The UEFI 2.3.1 specification states that:
"A minimum of 16,384 bytes of space must be reserved for the GPT Partition Entry Array."
and [the size of a partition entry shall be a power of two greater than 128]
and that [the defined fields of a partition entry total 128 bytes].

Clamping the entries means that no partitions on the drive will be detected,
as this will result in an incorrect partition entry array CRC. This change
reduces the likelyhood of useless partitions, while still not allowing a
huge kernel memory allocation to load the partition entries into.

In the future this code should probably be reworked to checksum and evaluate
the partition array in chunks while still limiting the number of GPT
wedges added per drive to something reasonable.

As discussed on tech-userlevel, add NetBSD GPT partition types for
swap, ffs, lfs, raidframe, ccd and cgd.  gpt(8) now defaults to
NetBSD ffs if no type is given, but previous FreeBSD types are
still recognized in the DKWEDGE_AUTODISCOVER code.
