Remove hard-coded SCRYPT N, R, and P values in modules, except where they are intentionally hardcoded.
Fix a bug that always caused a TMTO value of 1, even when it was not needed.
Respect device_available_mem and device_maxmem_alloc values even if a reliable low-level free memory API is present, and always select the lowest of all available limits.
Fix benchmark_deep.pl mask to avoid UTF-8 rejects.
Improve error messages when the check verifying that all SCRYPT configuration settings across all hashes are identical is triggered.
Also improve the error message shown when the SCRYPT configuration of the self-test hash does not match that of the target hash.
Fix a bug where a low-tuned SCRYPT hash combined with a TMTO could result in fewer than 1024 iterations, which breaks the hard-coded minimum of 1024 iterations in the SCRYPT kernel.
