23e9cf91f0 Ensure cpuminer-config.h is universally included, in *.c and *.h alike.
In miner.h, this fixes an alloca-definition-related warning.

For the other files, this is simply future-proofing/precaution.

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.

0b67740707 Pass max-nonce as arg to each sha256 algo.
Should be an equivalent transformation, with no behavior changes.
