Clean up multi-thread barrier-sync hold-down timerstable/1807
Main thread: don't bother with the barrier sync hold-down timer if none of the worker threads are busy. Worker threads: avoid epoll_pwait (10ms timeout) when the control-plane has been active in the last half-second. Cherry-pick a recent dangling reference fix: pool_elt_at_index after e.g. rx callback is required, in case the unix file pool expands. Manual feature backport to 18.07 Change-Id: I745fbb8a12aeda34b0ec7b6dcda66c0e25c3eee1 Signed-off-by: Dave Barach <dave@barachs.net>
