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.

7ddc893717 Add a quiet mode to ktrdump(1): if the "-q" flag is used, don't print 
the pretty text header on top of the output.  Simplifies feeding the
results of tracing into a script for mechanical processing.

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.

also be run on a core dump.
