666892792d Generate primes according to FIPS 186-4 
The specification requires that numbers are the raw entropy (except for odd/
even) and at least 2^(nbits-0.5). If not, new random bits need to be used for
the next number. Similarly, if the number is not prime new random bits need to
be used.

4bcb4914c5 Abort modular inversion when modulus is one. 
The modular inversion function hangs when provided with the modulus 1. This commit refuses this modulus with a BAD_INPUT error code. It also adds a test for this case.

a4af1c47d2 Correct sign in modular exponentiation algorithm. 
The modular exponentiation function  handled the sign incorrectly. This commit fixes this and a test case which should have caught it.

d1cc7f6f34 Fix buffer overflow in mbedtls_mpi_write_string() 
Fix a buffer overflow when writting a string representation of an MPI
number to a buffer in hexadecimal. The problem occurs because hex
digits are written in pairs and this is not accounted for in the
calculation of the required buffer size when the number of digits is
odd.

dbd443dca6 Adapted .function files and .data files to new test framework 
Changes include:
 - Integers marked with '#' in the .function files.
 - Strings should have "" in .data files.
 - String comparison instead of preprocessor-like replace for e.g. '=='
 - Params and variables cannot have the same name in .function files
