Message:

Fix problems with IPP threading. In psThreadPoolWait wait until all threads have
finished before returning even if one of the threads has a fault.
Return false if any thread faults. Also add a new argument bool harvestOnFailure
which tells psThreadPoolWait to harvest the done jobs if there is a failure.
Many functions previously used psThreadPoolWait(harvest = false) because they
wanted to examine the jobs structs afterwards. However they weren't cleaning up the
jobs in the failure case.
These now call psThreadPoolWait(harvest = false, harvestOnFailure = true)
which causes the jobs to be cleaned up on fault. These lingering jobs were the
cause of the "Unknown task" failure in psImageConvolve*
Also changed psphotReadout to check for failure of psphotGuessModels and return
to the caller. This yields quality = 3007
