Add a new function mbedtls_rsa_get_bitlen which returns the RSA key size, i.e. the bit size of the modulus. In the pk module, call mbedtls_rsa_get_bitlen instead of mbedtls_rsa_get_len, which gave the wrong result for key sizes that are not a multiple of 8. This commit adds one non-regression test in the pk suite. More tests are needed for RSA key sizes that are a multiple of 8. This commit does not address RSA alternative implementations, which only provide an interface that return the modulus size in bytes.
