cluster/ec: Handle CHILD UP/DOWN in all cases

        Backport of http://review.gluster.org/9396

Problem:
When all the bricks are down at the time of mounting the volume, then mount
command hangs.

Fix:
1. Ignore all CHILD_CONNECTING events comming from subvolumes.
2. On timer expiration (without enough up or down childs) send
   CHILD_DOWN.
3. Once enough up or down subvolumes are detected, send the appropriate event.
   When rest of the subvols go up/down without changing the overall
   ec-up/ec-down send CHILD_MODIFIED to parent subvols.
