A blocking binary heap based priority queue for tasks with deadlines has been
added. The priority queue sorts incoming tasks according to their
increasing deadline attribute.

This commit adds the deadline attribute to the task attributes struct.
The task deadline is an 64bit value.

On releasing all resources, the node waits for the completion of all
tasks which are associated to a specific action. Since we never
incremented the task counter for actions, this loop spun.

mtapi_c: adapted to new thread interface

mtapi_c: added organization ids, used version defines from base_c to fill info structure

mtapi_network_c: signaling of task completion is now atomic

(Merge was previously reverted accidentally. Re-applying merge to fix this.)

This reverts commit 554c76f7, reversing
changes made to fc660db0.

Fixed the buggy implementation of the id pool (did give out fewer elements as capacity, with repeated operations capacity was further reduced).

mtapi_c: do not notify all worker threads on task start, but just the one the task was initially assigned to
