3b89beb171 Attempt to improve the logic for automatically sizing partitions
to take into account the new default of starting the first partition
after the boot blocks instead of at sector 0. If you used automatic
sizing when the first partition did not start at 0, you would get
an error that the automatically sized partition extended beyond the
end of the disk.

Note that there are probably still many more complex cases where
automatic sizing and placement will not work (e.g. non-contiguous
or out of order partitions).

ccdd2fce3a Fix the derivation of the GEOM name from the specified device name by
complementing the existing special case of a not existing /dev prefix
with the recognition of an already existing /dev prefix.

This implicitly solves the following two issues related to working on
GEOM devices /dev/foo/bar (which have the GEOM provider name "foo/bar")
with the expected commands like "bsdlabel /dev/foo/bar":

1. the error "Geom not found" when trying to write or edit the BSD
   label (because previously the incorrect GEOM name "bar" instead of
   "foo/bar" was derived from "/dev/foo/bar").

2. the multiple times reported "magically introduced" partition offset
   of 63 blocks and the resulting errors like "partition extends past
   end of unit" and "partition c doesn't start at 0!".

   This implicitly resulted because bsdlabel(8) determines the "MBR
   offset" via GEOM and (intentionally) silently falls back to an offset
   of 0 if it could not be queried (which is the case if the name was
   incorrectly derived).

   Usually (at least on PCs) the offset for the first slice is 63 blocks
   and bsdlabel(8) automatically subtracts them from the absolute
   offsets in the read on-disk BSD label, resulting in the display of an
   effective offset of 0. If the GEOM query fails, the assumed offset of
   0 is subtracted and an incorrect effective offset of 63 is displayed
   and tried to be worked upon.

86e0bd0dc0 The disk labels generated by bsdlabel can no address more than
0xffffffff sectors.  Document this limit and avoid installing bogus
labels on disks with more sectors.

Allowing the installation of labels addressing as much of the disk as
possiable may be a useful addition in some situations, but this was easy
to implement and should reduce confusion.

640c9cb297 Remove the hardcoded default block/frag/cpg values from bsdlabel
and the logic for setting them according to the partition size.
Instead, unspecified filesystem values are left at 0 so that newfs
will use its own defaults. It just caused confusion to have the
defaults duplicated in two different places.

Don't look for disklabels every 16 bytes, look the only place they should

Always read the label from the raw disk and decode it into struct
disklabel rather than trust a cast from random addresses.

When writing to the raw disk, encode the label properly.
