  1. Run file verification in parallel threads 

    Build librpm with OpenMP support, refactor the file loop to use the
indexed rpmfiles objects instead of iterators.

On my rusty old laptop, this tends to just slow things down unless
things are hot in cache, in which case it roughly halves the running time.
Might be worth more on SSD based setup.

  1. Run rpmkeys -K package signature/digest checking in parallel 

    On my laptop this roughly doubles the runtime with cold cache, and
halves it with a hot cache: checking packages on loopback-mounted
Fedora-Server-dvd-x86_64-28-1.1.iso image takes about 33s serially and
60s in parallel when cold, and when hot, 20s serially and 10s parallel.
