Math-Prime-Util-0.47

Changes for version 0.47 - 2014-11-18

ADDED
- is_mersenne_prime(p) returns 1 iff 2^p-1 is prime
FUNCTIONALITY AND PERFORMANCE
- Standalone compilation (e.g. factoring without Perl installed) is easier.
- For next_prime and prev_prime with bigints, stay in XS as long as possible to cut overhead. Up to 1.5x faster.
- Factoring on 64-bit platforms is faster for 32-bit inputs.
- AKS is faster for larger than half-word inputs, especially on 64-bit machines with gcc's 128-bit types.
- is_provable_prime goes through XS first, so can run *much* faster for small inputs.
OTHER
- NetBSD improperly exports symbols in string.h, including popcount. Rename our internal function to work around it.
- is_power now takes an optional scalar reference third argument which will be set to the root if found. It also works for negative n.
- Changes to trim a little memory use. lucas_sequence goes from PP->[XS,GMP,PP] to XS[->PP[->GMP]]. ecm_factor is moved out of root. Moved some primality proving logic out of root.
- primes.pl when given one argument will show primes up to that number.
