configuring default values, retry with a smaller cluster size.
This makes the typical invocation to create a spec conformant EFI boot
partition work out of the box.
identd has aliasing violations, use -fno-strict-aliasing.
newfs_msdos's getbpbinfo() has missing {} issues.
sysctl's kern_cp_id() has missing {} issues.
but amusingly this did not include Block size, or Sectors per cluster.
Allow for all numeric parameters (If I want to specify the number
of drive heads as '1K', then why not?)
of track-size units: 2) the FAT metadata areas may not be a multiple of a
"track", 1) the partition may not be track-aligned to begin with, 0) what's
a "track"? is it something a robot rover leaves on Mars?
types. These values come from a publically-avaliable document of an
infallible source that must not be named due to a violation of the document's
license restrictions. This is justified by interoperability concerns.
afterwards. Fixes newfs_msdos at least on sparc. Incidentally,
the msdosfs tests also start working on sparc, which about halves
the number of test failures on that platform.
partutil.c::getdiskinfo to use it to get disk geometry info.
Use DIOCGWEDGEINFO ioctl to get information about partition size, if disk
driver doesn't support it use old DIOCGDINFO. This patch adds support for
wedge like devices(lvm logical volumes, ZFS zvol partitions) to newfs and
other tools.

necessary geometry when creating a file system directly to a file.
In addition, when creating, do not complain about the file not
being char special and do not try to execute device ioctl's on it.
count on "large" (>=32MB) file systems when fetching the geometry from
the medium. This confuses some software (which is to say Windows)
when a device newfs(8)ed under NetBSD is transported to another
system. (Note: The rest of the code uses 'bsec', and DTRT for smaller
file systems.)

and a number of sectors per track.
According to sys/fs/msdosfs/msdosfs_vfsops.c:msdosfs_mountfs(),
the kernel doesn't accept BPB with spt (sector per track) > 63
or hds (drive heads) > 255, so if values taken from disklabel
don't match these restrictions, use popular BIOS default values
(255/63) instead.
