Make the next work item queue 2/3 of the way through the work on the current work item.
...
Load the first queued extra work in the main function to avoid having a once-off variable in get_work().
Load an extra set of work for each function in advance once a longpoll is detected since every thread will need to get new work.
Discard requests with a separate function to ensure the right number is always queued.

Logic error in the queueing of work ended up generating more stale blocks.
...
There is a small chance that a longpoll is signalled right at the start which would lead to a deadlock so check for first work before restart.

Get rid of the requirement for a static struct that needs locking to cache work.
...
Make it possible to use the thread id for getting work again.
Flag the getwork() function when we have a new block to explicitly discard any cached work when a new block is detected.
Store the header of each new work and compare it to blocks we're about to submit to decide if they're stale due to a new block and don't try to submit them.
This should significantly decrease the number of rejected blocks.

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.

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.
