The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

(cherry picked from commit 4d846d260e)
libpmc already returns an end address that is after the end of the
last instruction of a function (on both amd64 and arm64) as the end
address written to the annotate map file is computed as the start
address of the symbol plus the size.
Adding one could result in a curious failure where an entire
function's contents in assembly was reduced instead to only the first
instruction. The reason is that when the end instruction is bumped by
one, objdump -d can append the first instruction of the next function
in its output. However, since pmcannotate concatenates all of the
objdump -d output from various functions into a single file which it
then searches to find the assembly for a given file, if this
additional trailer was earlier in the file than the full function, the
trailer was chosen to represent the entire function resulting in the
truncated listing of the function.

(cherry picked from commit 73702c3980)
Convert pmcannotate to using $TMPDIR and _PATH_TMP rather than hard
coding /tmp for temporary files. Pmcannotate sometimes needs quite a
lot of space to store the output from objdump, and will fail in odd
ways if that output is truncated due to lack of space in /tmp.

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.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

FreeBSD9 and CURRENT. Removing this rather unnecessary check which expects the
second character of assembly line to be a hex number to make pmcannotate
actually annotate the code and assembly.

Although groff_mdoc(7) gives another impression, this is the ordering

I was considering committing all these patches one by one, but as
discussed with brooks@, there is no need to do this. If we ever
need/want to merge these changes back, it is still possible to do this
per application.
