32fd57a8e1 Remove nfsstat. Running nfsstat in crashinfo will give the stats of the
running kernel instead of the stats of the crashed kernel. The current
version uses sysctls to query the stats and does not work at all (anymore)
on crash dumps.

33bb3dbe38 crashinfo: stop looking for gdb in /usr/bin/gdb
As of r359457 we removed the GDB_LIBEXEC option, always installing in-tree
gdb into /usr/libexec/.  Thus, there is now no need for crashinfo to include
/usr/bin/gdb in the list of pathnames to check when looking for gdb.

6f77212f27 Support compressed crash dumps in crashinfo(8).
Temporarily decompress a copy of a crash dump compressed with either
gzip or zstd and run various tools against the decompressed copy while
generating the crash information.  The uncompressed copy is deleted when
the script exits.

Note that crashinfo is enabled by default, so this will attempt to
decompress the most recent compressed crash dump after a crash that
generates a compressed crash dump.  Users who wish to only do offline
analysis of compressed crash dumps can disable crashinfo in rc.conf.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

5a3924b985 Allow matches of truncated version strings.
Long objdir paths make it easy to hit the version string length limit in
kernel dump headers. The build number and timestamp are unlikely to be
truncated and ought to be sufficient to protect against false positives.

73ad3fb536 Add a new GDB_LIBEXEC option to install gdb and kgdb to /usr/libexec.
When this option is enabled, only gdb and kgdb are installed to
/usr/libexec for use by crashinfo(8). Other bits of GDB such as
gdbserver and gdbtui are not installed. For this option to be
effective, GDB must be enabled.

Rework r317094 to re-enable GDB on all platforms but enable
GDB_LIBEXEC on platforms for which the GDB in ports is a superset of
functionality.

241cf416c9 Update crashinfo to work with newer gdb from ports.
If gdb from ports is installed, use it instead of the base system gdb
to extract variables from a kernel.  Note that base gdb and ports gdb
do not support the same options for invoking a single command in batch
mode, so a wrapper shell function is used.  In addition, prefer kgdb
from ports when generating a backtrace if present.

ccfb965433 Add META_MODE support.
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.

7ad50a360b Improve multi-line kernel ident parsing
Instead of blindly grabbing the line with 'Version string' and the
following one from the core info file, take all lines after 'Version
string' until the one one that matches the field format in the core info
file.  This provides compatibility with VendorBSD modifications that have
a different kernel ident format.

9decd44681 Teach crashinfo(8) to look at the currently running kernel (based on the
kern.bootfile sysctl).  Prior to this commit, crashinfo(8) only looks at
/boot/*/kernel; this includes the usual places where kernels reside, so
for most systems this will have no effect.

a37f97161c Add a script to perform simple analysis of a crash dump (either a full
dump or minidump).  When the script is run, it generates a text file
containing the output of several commands run againt the core dump such
as kgdb (stack trace), ps, netstat, vmstat, iostat, dmesg, and fstat.
