    ck: add support for executing callbacks outside of main poll loop

    Pull in change from upstream deca119d14bfffd440770eb67cbdbeaf7b57eb7b

    |    ck_epoch: introduce ck_epoch_deferred
    |    Allow for deferral to occur outside epoch poll critical loop (which 
may access per-CPU structures).

   CK was imported in vendor-sys/ck, commiting directly into head will
cause some problems in the future.
Actually ... committing to head is fine: some things just have to be fixed.
  This is not true, it can cause a lot of problems with futures updates
if the change isn't in the vendor repo.
OK ... I meant generally you can. The catch here is that the change was already upstream so it should have been done in the vendor area and then merged. It's best to fix this properly now.

Sorry for misguiding.


We do ask you try to upstream the change and re-merge things when possible.
  This is already upstream, Matt is just updating CK with a patch he did
