Add support for WellRNG 512a
This is a "new" random number generator. Derived from code published at:

<QUOTE>
In this paper, we propose new generators, with better equidistribution and
âbit-mixingâ
properties for equivalent period length and speed. Approximately half of
the coefficients
of the characteristic polynomial of these generators are nonzero. The state
of our new
generators evolves in a more chaotic way than for the Mersenne twister.

Many thanks to Pierre L'Ecuyer for GPL'ing the code so that it could
be used in this project.

Add support for using Tiny MT, a 128 bit state RNG
Perl traditionally uses the systems random number generator
for the rand() function. This means that the behavior of code
using it is platform dependent. Worse, sometimes the random
number generator is of poor quality.
This patch adds support for using the TinyMT random number
generator (32 bit version) instead. This generator is of relatively high
quality, uses 128 bits of state and is relatively fast and should be
portable to all of our build targets.
Note that this patch does not *enable* using tinym32, to do that
you need to define TINYMT32 during configure.
Full details of the algorithm can be obtained at
