7528a95fe1 Perform global libcurl initialization 
curl_easy_init() is not thread-safe unless curl_global_init() has
already been called.
It seems that SSL initialization is slow on Windows, so only do that
if the mining server has to be accessed via HTTPS.
Thanks to @martinwguy for pointing this out.

b6f26e1acc Add "cert" option for rpc server's self-signed SSL certificate 
When minerd is used across the internet, the server's rpc userpass
travel unexcrypted, allowing anyone en route to copy them and
empty the server's wallet. Using https: would prevent this
but minerd's SSL connection fails on self-signed certificates.

This change adds a "-cert file" option (cert:"file" in minerd.conf)
to tell minerd the filename of the server's self-signed certificate.

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.
