Daily work -- Convert random inlines and helper calls into bw::random calls

This PR changes random accesses, and I would love a second pair of eyes on it. I found a bunch of cases of e.g. helper::randomize_short(#) and inlined g_last_random_number management that I have converted into bw::random() calls. Hopefully, I did them all correctly!

This isn't intended to stop desyncs, but it will add logging to all GPTP-based random calls, which will hopefully give us more info when the next desync does occur.
