Johan Hedberg a95b6eeafb nano_work: Fix never yielding from fiber
If the delayed work FIFO never goes empty (e.g. because the work
callback keeps resubmitting or there's a very active ISR feeding items
there) then the fiber would never yield, causing all sorts of problems
for the system. Adding an explicit fiber_yield() call at the end of
the while-loop solves the issue.

Luiz Augusto von Dentz b559c1bca2 nano_work: Add delayed version
This adds a delayed version of nano_work API which is useful when
handling timeouts since the same stack/workqueue can be shared.

Vlad Dogaru 818a2e2975 nanokernel: Introduce workqueue API
Add a generic API for drivers to start workqueues and submit work
items.  This is needed by drivers which need to schedule code that might
sleep from an ISR to run in fiber context.

Also add the option to start a system-wide workqueue.

Both additions are optional.  They can be deactivated for systems that
do not need them.
