2018-04-19	Reconstruct the hashsig hash tree(s) on device restart.	Paul Selkirk
	This can take long enough (several minutes for h=10) that we do it in a background task, which is then converted to an RPC dispatch task. Also add a very limited form of free(), to free the topmost allocation in the sdram "heap". I don't want to deal with real heap management, but I do want to be able to recover memory upon deleting a hashsig key, if it's easy to do so.
2017-05-01	Add HAL_Delay as an alias for task_delay, but don't wedge if the tasker ↵	Paul Selkirk
	isn't running yet.
2017-04-29	Add minimal mutexes to the minimal tasking system	Paul Selkirk

2017-04-29	Add task_delay.	Paul Selkirk

2017-04-27	Replace the RTOS with a simple cooperative tasker.	Paul Selkirk
	There are no priorities and no preemption, so tasks run in a round-robin fashion, and explicitly yield control.
