Add new #define's for Crypt_Int* numbers, which are compatible to bigNum
anf bitConst. Only add some functions that support Crypt_Int* in this step.

Bn2bin was used during the conversion of the code for supporting OSSL 1.1
and testing the math results of < OSSL 1.1 against those produced by
the bignum code in the TPM 2. It's not needed anymore since the upstream
code has support for any OSSL version now.

Mark all libtpms changes with comments for easy identification
when diff'ing with the original TPM code.

Port the TPM 2 code to OpenSSL 1.1 by accessing the OpenSSL BIGNUM
only via its public functions. To get there it is necessary to
implement the Bn2bin() function that converts the TPM internal
representation of a bigNum to an array of unsigned chars that can
then be passed to the OpenSSL BN_bin2bn() function.
