efebee5ab8 Fix the case where there are no GPUs, and exit if they give errors. 
If there are no GPUs, set nDevs to 0 not -1 (status is set to an
unhelpful -1001 here on my laptop, so we can't rely on a particular
status value).

Also, if nDevs is -1, exit rather than screwing up later.

3aa5be4fcf Reinstate binary kernel loading with fixes. 
Build binaries with unique filenames from the kernel generated and save them.
Try to load this cached binary if it matches on next kernel instantiation.
This speeds up start-up dramatically, and has a unique kernel binary for different kernel configurations.

2b6e841673 Use a buffer of up to 512 * 4 integers when retrieving work from the GPU. 
This allows each local thread id to have one slot to put any positive results into, thus making overlapping results far less likely.
Thus races will be much rarer, allowing more threads.
It should also pick up blocks close to each other more reliably and hopefully decrease the number of rejects and opencl errors.
Do the search over the buffer entirely in a separate thread to allow the GPU to stay as busy as possible.
Detach threads from themselves to prevent unlucky even where dereferencing occurs by freeing the data that stores the thread info.

6374e0fafe Import the phatk kernel. Enable it only for hardware with amd media ops for now since it crashes nvidia et. al. 
Fallback to the poclbm kernel for the rest. Try harder to avoid stale blocks around longpoll detecting new blocks.

2dbb39444d Base was being set wrongly meaning we were repeating searches and the rate was actually lower than displayed :( 
Tweak Ma with new changes.
Change default vectors to 2 since it's faster than 4 even when 4 is reported as preferred.
