Add an API-alike equivalent library for openssl BIGNUM functionality.
This is accomplished using the libtommath MPI implementation
internally, without exporting any functions. All of the BIGNUM
functionality to provide working netpgp signatures, verification,
encryption and encryption is provided.
Functions and macros included:
BN_is_negative(x)
BN_is_zero(a)
BN_is_odd(a)
BN_is_even(a)
