8a832eeab5 Linux + x86_64 optimisations. 
Add likely() macro.
Optimise a few obvious code paths with likely/unlikely.
Change algo to sse2_amd64 by default.
Move priority change to worker threads only.
Detect number of CPUs and set default number of threads == CPUs.
Add scheduling policy change to worker threads to SCHED_IDLE first and fallback to SCHED_BATCH on linux.
Don't error when failing to set priority.
Add CPU affinity and bind worker threads to CPUs when number of threads is a multiple of number of CPUs.
Update NEWS with changes.

714c0fd7c9 Continue scanhash, even if high 32 bits are zero. 
Previously, we would stop the scan if the high 32 bits of the hash were zero,
as a quick shortcut for testing the full hash.  If this quick test succeeded,
we would pass the work to the server for full validation.

Change this logic to perform full validation inside minerd, so that work may
be resumed more quickly if hash > target.
