decb927685 Add an assertion to try to please coverity.
Coverity, for some reason, thought that weight_scale might be 0,
leading to a divide-by-zero error.

602c52cad4 Coverity deadcode shenanigans on BUG() macro.
We don't actually want Coverity to complain when a BUG() check can
never fail, since such checks can prevent us from introducing bugs
later on.

Closes ticket 23054. Closes CID 1415720, 1415724.

250c88014d Always start with one additional worker thread
Now that half the threads are permissive and half are strict, we
need to make sure we have at least two threads, so that we'll
have at least one of each kind.

bddea78ded Fix a pair of stale comments in workqueue.c
These comments said that each thread had a separate queue, but we
haven't been using that design for some while.

efadebf7c3 Make the chance for priority inversion thread-specific
Instead of choosing a lower-priority job with a 1/37 chance, have
the chance be 1/37 for half the threads, and 1/2147483647 for the
other half.  This way if there are very slow jobs of low priority,
they shouldn't be able to grab all the threads when there is better
work to do.

10e0bff4ca Add support for multi-priority workqueues
Each piece of queued work now has an associated priority value; each
priority goes on a separate queue.

With probability (N-1)/N, the workers will take work from the highest
priority nonempty queue.  Otherwise, they'll look for work in a
queue of lower priority.  This behavior is meant to prevent
starvation for lower-priority tasks.

1a907c6593 Merge branch 'maint-0.3.0' into maint-0.3.1
This is an "ours" merge to avoid taking any changs from maint-0.3.0:
we don't want to take the travis file, since there is a separate branch
for putting it in 0.3.1 and later.

32b9edeb91 Fix build warnings from Coverity related to our BUG macro
In the Linux kernel, the BUG() macro causes an instant panic.  Our
BUG() macro is different, however: it generates a nonfatal assertion
failure, and is usable as an expression.

Additionally, this patch tells util_bug.h to make all assertion
failures into fatal conditions when we're building with a static
analysis tool, so that the analysis tool can look for instances
where they're reachable.

Fixes bug 23030.
