Change default number of threads back to 1. The 2nd just increases the time taken to complete a work item thus increasing stale blocks, despite increasing the rate slightly.

configure.ac, Makefile.am: Allow setting of OpenCL location
Add two new configure flags, --with-opencl-libdir and --with-opencl-inc
to specify where OpenCL headers and libraries exist. This now adds
a test for the OpenCL header file and makes not finding the library
or headers a fatal error.

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.

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.
