Put work into a staging area which makes it possible to check the latest work data received.
Then check the latest work data against a store of the current_block and use it to determine if we have moved to a new block.
This makes --no-longpoll work just as efficiently as longpoll, and works around when longpoll is unreliable.

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.

Cleanup --cpu-threads/-t logic
Currently it gets negated which means the default printed is wrong.

haven't, and they turn off the GPUs, reset it to num_processors.

Use ccan/opt for commandline parsing.
This cleans up option handling, by using ccan/opt rather than
handcoded getopt_long. We still have to open-code some things, such
as json config file handling.
The main change is that the --config option causes a file to be parsed
during commandline parsing, so you can override the results, and
provide multiple of them.
Other improvements are that 'help' and 'ndevs' are not valid arguments
in the config file; we use a separate argument table for such
commandline-only flags.

This should significantly decrease the number of rejected blocks.

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.
