Equivalent of Linux Workqueues

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

Another caveat with DADHI porting: that require something like 
Linux Workqueues feature:
http://www.kernel.org/doc/htmldocs/device-drivers/ch01s06.html
(It only uses schedule_work, cancel_work_sync and flush_work).

This is about queuing function execution, cancel it, or wait for it 
to complete,  Do we have something similar in our kernel, or should
I implement a dedicated thread with a queue of functions to run?
