Use a pthread conditional that is broadcast whenever work restarts are required. Create a generic wait function waiting a specified time on that conditional that returns if the condition is met or a specified time passed to it has elapsed. Use this to do smarter polling in bitforce to abort work, queue more work, and check for results to minimise time spent working needlessly.

Extend nrolltime to support the expiry= parameter. Do this by turning the rolltime bool into an integer set to the expiry time. If the pool supports rolltime but not expiry= then set the expiry time to the standard scantime.

Changed work_reset rate to every 100ms & use defines rather than numerics.
Change total sleep time to 4300ms after performance testing/measurement (now good to 916MH/s).
Changed timeout to 15s - Throttle time is 15s.
Added support for 'Busy' when submitting work.
Improved logging text to include device identifier.
Added a thread_enable api function, called when a thread is re-enabled.
... and removed useless re-init inside scanhash.

Idle is only set by pgadisable, so GPU/CPU is unaffected.
For Icarus/Ztex, in scanhash the thread is immediately set disabled then returns.
