pthreadpool: Avoid a malloc/free per job
pthreadpool_add_job is in our hottest code path for r/w intensive workloads, so
we should avoid anything CPU-intensive. pthreadpool used to malloc each job and
free it in the worker thread. This patch adds a FIFO queue for jobs that helper
threads copy from, avoiding constant malloc/free. This cuts user space
CPU in the local-bench-pthreadpool benchmark by roughly 10% on my system.
