[ADDED]
- is_totient(n) true if euler_phi(x) == n for some x
[FUNCTIONALITY AND PERFORMANCE]
- is_square_free uses abs(n), like Pari and moebius.
- is_primitive_root could be wrong with even n on some platforms.
- euler_phi and moebius with negative range inputs weren't consistent.
- factorialmod given a large n and m where m was a composite with
large square factors was incorrect. Fixed.
- numtoperm will accept negative k values (k is always mod n!)
- Split XS mapping of many primality tests. Makes more sense and
improves performance for some calls.
- Split final test in PP cluster sieve.
- Support some new Math::Prime::Util::GMP functions from 0.47.
- C spigot Pi is 30-60% faster on x86_64 by using 32-bit types.
- Reworked some factoring code.
- Remove ISAAC (Perl and C) since we use ChaCha.
- Each thread allocs a new const array again instead of sharing.
