Make sure that the provider sector size is large enough to contain a
valid label before trying to read it. We performed this check already
for most label types, but not for several filesystem labels.

routines out.
While there, also simplify the creation of label paths a little bit
by requiring the / suffix for label directory prefixes (ld_dir renamed
to ld_dirprefix to indicate the change) and stop defining macros for
these when they are only used once.

Similar to what was done for device_printfs in r347229.
Convert g_print_bio() to a thin shim around g_format_bio(), which acts on an
sbuf; documented in g_bio.9.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
for specific "kinds" of disk labels - for example, GPT UUIDs. Reason
for this is that sometimes, other GEOM classes attach to these device
nodes instead of the proper ones - e.g. they attach to /dev/gptid/XXX
instead of /dev/ada0p2, which is annoying.
