AP6 r1363 for GPU

Raistmer:
New switch added:
-initial_ffa_sleep N M
where N - number of ms to sleep in short PC-FFA, M - number of ms to sleep in large FFA. This sleep will occur before polling for event loop in -use_sleep case (and this sleep independed from -use-sleep switch)

Recommended usage:

1) do test run with -v 2 -use_sleep options.
2) look into stderr.txt for usual sleeping times for short and large FFA (they will differ considerably)
3) Enter those usual values (or those -1ms) into this new switch parameters fialed.
4) additional run with this param "+" -v 2 -use_sleep can be done to check if sleep loop times now much smaller (1-2ms). Then -use_sleep can be omitted at all.

Take care, this switch requires exactly 2 params (2 integer numbers separated with space), not 1.

Is this new switch for all (NVidia & AMD?ATI) devices/GPUs or NVidia only.

Raistmer:
It's for all GPU AP builds.
[But how helpful it would be for particular vendor/device/driver config - need to test in each particular case]

Works very well on my 7970.  many non zeroed WU's completing in less than an hour.

No errors to report.
