Refactor the CPU scanhash_* functions to use a common API. Fixes bugs.
- Before, some returned bool, and others returned int (which was then turned
into a bool with a comparison); now, everything returns a bool
- Before, some set hashes_done to nonce - 1 when a share was found and others
set it to nonce + 1 or 2. This caused some algorithms to scan/submit shares
twice with the new cpu_scanhash function. Now, it has all been replaced with
last_nonce, which is set to the final nonce checked by the scanhash_* func.
- VIA needs the full data, and cannot use midstate. All the others were
expecting midstate and data+64 for their parameters. Now, we pass midstate
and the full data pointer, and let the scanhash_* function choose which to
use.

Update CPU reentrant scan code to work properly for extended periods up to scantime and adjust rate properly.
Simplify locking in hashmeter since it's called relatively infrequently anyway.
Set gpuminer hashmeter interval update to log interval / 5 as well.

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.

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.

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