Make procstat(1) recognize process descriptors, so that it shows "P" instead of "?" in "procstat -af" output. Note that there are still a few more DTYPE_* kinds we don't decode yet. Sponsored by: DARPA, AFRL

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.

Add support for capturing 'struct ptrace_lwpinfo' for signals resulting in a process dumping core in the corefile. Direct stable changed: Padding added to struct thread and td_si added to end with explicit bzeroing when forking/initializing a thread to preserve KBI.

Start writing up some basic feature tests for procstat These tests query a running process for information related to the -b, -c, -e, and -f flags; the -f testcase is largely stubbed out, pending additional work to determine a good, deterministic descriptor. Core file test support is coming soon--it requires a bit more effort due to the fact that: - coredumps can be disabled (kern.coredump=0). - corefiles can be put in different directories than the current directory, or be named something other than `.core` (`kern.corefile`).

r318175: procstat(1): clarify the Signal Disposition section - Fix a typo (SIGIGN -> SIG_IGN). Use .Dv when referencing SIG_IGN. - Use semi-colons as soft breaks when separating sentences for the FLAGS section. - Tweak wording for C slightly to flow better and to be a bit more technically correct (signals with handlers installed will be caught by the target program). - Reference signal(3) in the SEE ALSO section. r318178: procstat(1): document all possible `PRO` (network protocol) values Reference the appropriate section 4 manpages for networking protocols. r318179: procstat(1): also reference icmp(4) and sctp(4) This was missed in the previous commit by accident.

Export the whole thread name in kinfo_proc kinfo_proc::ki_tdname is three characters shorter than thread::td_name. Add a ki_moretdname field for these three extra characters. Add the new field to kinfo_proc32, as well. Update all in-tree consumers to read the new field and assemble the full name, except for lldb's HostThreadFreeBSD.cpp, which I will handle separately.
