Signal handling in dns lookup code is responsible for libcurl crashes when multithreading.
...
Disable signal handling and use many curl handles instead, thus making work more asynchronous.
Theoretically a curl can wait forever on a dns lookup with this but it's extremely unlikely.

With pre-emptive queueing of work there is no need to have extra work in the queue by default. Make it a list of extra queue items instead of a total and default to 0.

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.
