libmp: fix mpmod() aliasing bug when n == r and x < 0 (thanks aiju, mischief)
...
mischief found this in rsafill()'s call mpmod(c2, x, x), where
d parameter is negative (rsagen created a rsa key with negative dk).

libmp: mpnrand(), what was i *THINKING*
...
the prior implementation was unneccesarily complicated for
no good reason due to me misunderstanding how libc's nrand()
works. in contrast to libc, we already generate the *closest*
power-of-2 random number with mprand() in the sampling loop.

libmp: add mpfield() function for fast field arithmetic
...
instead of testing for special field primes each time in mpmod(),
make it explicit with a mpfiled() function that tests a modulus N
to be of some special form that can be reduced more efficiently with
some precalculation, and replaces N with a Mfield* when it can. the
Mfield*'s are recognized by mpmod() as they have the MPfield flag
set and provide a function pointer that executes the fast reduction.
