machine/stdarg.h -> sys/stdarg.h

Switch to using sys/stdarg.h for va_list type and va_* builtins.

Make an attempt to insert the include in a sensible place. Where
style(9) was followed this is easy, where it was ignored, aim for the
first block of sys/*.h headers and don't get too fussy or try to fix
other style bugs.

GEOM: Introduce partial confxml API

Traditionally the GEOM's primary channel of information from kernel to
user-space was confxml, fetched by libgeom through kern.geom.confxml
sysctl. It is convenient and informative, representing full state of
GEOM in a single XML document. But problems start to arise on systems
with hundreds of disks, where the full confxml size reaches many
megabytes, taking significant time to first write it and then parse.

This patch introduces alternative solution, allowing to fetch much
smaller XML document, subset of the full confxml, limited to 64KB and
representing only one specified geom and optionally its parents. It
uses existing GEOM control interface, extended with new "getxml" verb.
In case of any error, such as the buffer overflow, it just transparently
falls back to traditional full confxml. This patch uses the new API in
user-space GEOM tools where it is possible.

Reimplement aliases in geom

The alias needs to be part of the provider instead of the geom to work
properly. To bind the DEV geom, we need to look at the provider's names and
aliases and create the dev entries from there. If this lives in the GEOM, then
it won't propigate down the tree properly. Remove it from geom, add it provider.

Update geli, gmountver, gnop, gpart, and guzip to use it, which handles the bulk
of the uses in FreeBSD. I think this is all the providers that create a new name
based on their parent's name.

Extend stripeoffset and stripesize of GEOMs from u_int to off_t

GEOM's stripeoffset overflows at 4 gigabyte margin (2^32)
because of its u_int type. This leads to incorrect data in the output
generated by "sysctl kern.geom.confxml" command, "graid list" etc.
when GEOM array has volumes larger than 4G, for example.

This change does not affect ABI but changes KBI. No MFC planned.

sys/geom: adoption of SPDX licensing ID tags.

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.
