Replace literal uses of /usr/local in C sources with _PATH_LOCALBASE

Literal references to /usr/local exist in a large number of files in
the FreeBSD base system. Many are in contributed software, in configuration
files, or in the documentation, but 19 uses have been identified in C
source files or headers outside the contrib and sys/contrib directories.

This commit makes it possible to set _PATH_LOCALBASE in paths.h to use
a different prefix for locally installed software.

In order to avoid changes to openssh source files, LOCALBASE is passed to
the build via Makefiles under src/secure. While _PATH_LOCALBASE could have
been used here, there is precedent in the construction of the path used to
a xauth program which depends on the LOCALBASE value passed on the compiler
command line to select a non-default directory.

This could be changed in a later commit to make the openssh build
consistently use _PATH_LOCALBASE. It is considered out-of-scope for this
commit.

cpucontrol: check for the supposed firmware file type and skip

do_update() skips entries with DT_DIR type. This does not eliminate
other entries that might exist in the directory. More, since NFS
might fill d_type with DT_UNKNOWN, dot and dotdot entries are not
skipped, then mmap(2) call failed for them when update microcode files
are located on NFS.

Add cpuctl(4) ioctl CPUCTL_EVAL_CPU_FEATURES which forces re-read of
cpu_features, cpu_features2, cpu_stdext_features, and
std_stdext_features2.

The intent is to allow the kernel to see the changes in the CPU
features after micocode update. Of course, the update is not atomic
across variables and not synchronized with readers. See the man page
warning as well.

various: general 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.

No functional change intended.

Allow to disable default microcode updates search path with the new
'-n' option.

Look for updates in the default locations only after user-supplied
locations are tried.

If newer microcode files are put into non-standard path, both measures
allow to avoid situation where older update loaded from the default
path first, and then the second update is applied from non-standard
path. Applying intermediate updates might be undesirable.

Add support for microcode update on newer AMD CPUs (10h+)

This includes new code for parsing microcode files as well as
the kernel-side change to apply the update on all processors
at the same time.

Developed with help from Borislav Petkov, formerly bp@amd64.org.

Tested using Athlon II X2 processor on a system where BIOS does
not have the latest microcode version:
/boot/firmware/microcode_amd.bin: updating cpu /dev/cpuctl0 to revision 0x10000c7... done.

The microcode file is taken from here:

(note that the original site seems to be down at the moment)
