If hash_calculate is invoked with region_count = 0, it will try to hash
INT_MAX regions. We should check this parameter.
* Avoid a comparison with different signedness.
* Check that region_count is at least 1.
* Avoid a superfluous assignment.

This file has a lot of conditional code and much of it is unnecessary.
Clean this up to reduce the number of build combinations.

rsa-checksum.c sontains the hash_calculate() implementations. Despite
the "rsa-" file prefix, this function is useful for other algorithms.
To prevent confusion, move this file to lib/, and rename it to
hash-checksum.c, to give it a more "generic" feel.
