Math-Prime-Util

Changes for version 0.67 - 2017-09-23

ADDED
- lastfor stops forprimes (etc.) iterations
- is_square(n) returns 1 if n is a perfect square
- is_polygonal(n,k) returns 1 if n is a k-gonal number
FUNCTIONALITY AND PERFORMANCE
- shuffle prototype is @ instead of ;@, so matches List::Util.
- On Perl 5.8 and earlier we will call PP instead of trying direct-to-GMP. Works around a bug in XS trying to turn the result into an object where 5.8.7 and earlier gets lost.
- We create more const integers, which speeds up common uses of permutations.
- CSPRNG now stores context per-thread rather than using a single mutex-protected context. This speeds up anything using random numbers a fair amount, especially with threaded Perls.
- With the above two optimizations, randperm(144) is 2.5x faster.
- threading test has threaded srand/irand test added back in, showing context is per-thread. Each thread gets its own sequence and calls to srand/csrand and using randomness doesn't impact other threads.
