Avoid writing directly into fp_digits through char*.
...
There are potential issues with weird platforms were not
all bits of a fp_digit are used (padding bits), plus it
makes it harder to do reproducible testing of algorithms.

Remove usage of malloc() from fp_prime_random_ex.
...
This is the only instance of dynamic memory in TFM. It can be avoided
by writing directly into the dp[] array, and it does not violate C
aliasing rules which specifically allow access on objects through char*.
It does not matter the platform-specific representation of digits since
we are filling them with random data anyway.

Avoid always generating 0x80 as MSB in primes.
...
When we ask to generate a prime whose size is a multiple of 8,
the code wrongly computes the mask as 0x00 instead of 0xFF, so the
generated prime always has the MSB set to 0x80 (the highest bit is OR'ed
later in the code).
