45dc116cb7 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.

819c32b42c when scanning for disklabels, close block device only when this was 
the first open. The device driver doesn't do reference counting.

This is still subject to race conditions.

c60db2e923 make more drivers use disk_ioctl, and add a dev parameter to it so that 
we can merge the "easy" disklabel ioctls to it. Ultimately all this will
go do dk_ioctl once all the drivers have been converted.

bdddf44518 disk_blocksize and disk_set_info relay the same information 
to the disk subsystem.

Make disk_set_info also set blocksize shift values.
Remove every call to disk_blocksize.

Keep disk_blocksize for ABI compatibility, make it also set dg_secsize.

bb7c004bd3 When converting a disklabel partition type integer to a wedge partition 
type string, use the strings defined in DKW_PTYPE_* in <sys/disk.h>, not
the strings defined in FSTYPE_DEFN in <sys/disklabel.h>.

This corrects a problem introduced in revision 1.21 dated 2014-08-18.
That change was intended to add additional case to the list, but it
accidentally also changed from the strings in the DKW_PTYPE_* macros to
the strings in the FSTYPE_DEFN macro.  Many of the strings are the same,
but there are differences such as "RAID" versus "raidframe" and "MSDOS"
versus "FAT".

XXX: There seems to be no good reason for the differences in string
names for partition types.  One or both of the lists should probably be
edited to align them.

cc5c10ea14 Make dk(4) discard from partition start, not from disk start. 
Otherwise, anything mounted with `-o discard' will pretty quickly
munch itself up and barf up an unrecoverably corrupted file system!

a68f9396b6 Change (mostly mechanically) every cdevsw/bdevsw I can find to use 
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
