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.

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.
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.
- 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.

to get a better sense of latency between events, such as time to
schedule an interrupt thread from time the interrupt occurred. Assert

length was used for the table header, which resulted in the header
not lining up with the table.
