pkill: use an ARG_MAX size buffer for argument matching

Right now pkill/pgrep cut off at _POSIX2_LINE_MAX (2048), but argument
strings can be much larger (ARG_MAX is 256K/512K). Stop arbitrarily
cutting the search off at 2K, rather than documenting the limit.

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.

The r322210 change to pgrep's PID delimiting behaviour causes pgrep's default
output to not include a trailing new line, which is a potential POLA violation
for existing consumers. Change pgrep to always emit a trailing new line on
completion of its output, regardless of the delimeter in use (which technically
is also a potential POLA violation for existing consumers that rely on the
pre-r322210 buggy behaviour, but a line has to be drawn somewhere).
