1de7b4b805 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.

8e15d40d24 Provide an error message if KTR symbols in a vmcore cannot be resolved.
libkvm does not set an error string in this case, so we were previously
failing silently.

208a859459 ktrdump(8): Capsicumify
We restrict the (optional) input file and output files. It would be
nice to restrict the KVM files, but that's up to libkvm.

We wait until after kvm_nlist() is invoked to cap_enter() because
kldsym() isn't supported in the Capsicum sandbox.

cf990407e1 Update dependencies after r291406 added libelf to libkvm.
Unfortunately filemon/meta mode tracks all indirect dependencies here
since ld(1) is reading libelf when linking in libkvm.  Churn would be
reduced if this was able to be limited to direct dependencies.

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.

to a crash dump and kernel, respectively.  The existing -m/-e flags are
still supported for backwards compatiblity but are no longer documented.

3447a66db8 Don't dump entries that were modified during the time the KTR buffer was being
copied to userspace. Failing to do this would result in entries at the bottom
of the ktrdump output to be more recent than entries at the top.

With this change the timestamps are monotonically decreasing going from the
top to the bottom of the ktrdump output.

f8c8b7ee8f Fix an issue with ktrdump(8) where it would not print all entries in the
KTR buffer.

This happens when 'i' tries to wrap around from 0 to 'entries - 1'. Since 'i'
is a signed integer the modulo operation actually returns a negative number.

Fix this by computing the next index to use "by hand" instead of relying
on the modulo operator.

28d91af30f - Implement run-time expansion of the KTR buffer via sysctl.
- Implement a function to ensure that all preempted threads have switched
   back out at least once.  Use this to make sure there are no stale
   references to the old ktr_buf or the lock profiling buffers before
   updating them.

ee574da534 Really fix the relative timestamp bug. It was only incorrect for the ALQ
case.  It seems entries are in reverse order when read from the kernel
memory but in the right order when read from a file (i.e. ALQ).  Handle
both cases.

7d8c7fe102 Add a "-r" flag to ktrdump(1) to print relative timestamps when used
with "-t" rather than absolute timestamps.  This allows the reader
to get a better sense of latency between events, such as time to
schedule an interrupt thread from time the interrupt occurred.  Assert
a copyright on ktrdump.c since I seem to be modifying it more than I
thought.

dd6cf019f3 When the 'f' flag is passed to ktrdump(1), use 40 characters for the
"file and line" field consistently; previously, a 32-character field
length was used for the table header, which resulted in the header
not lining up with the table.
