- 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.

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.

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.

Add a quiet mode to ktrdump(1): if the "-q" flag is used, don't print

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.
