* but the required size for private keys.

* If modp is NULL, reduction modulo P is done using a generic algorithm.
* Otherwise, it must point to a function that takes an mbedtls_mpi in the range
* 0..2^(2*pbits)-1 and transforms it in-place in an integer of little more

* Error code layout.
*
* Currently we try to keep all error codes within the negative space of 16
* bits signed integers to support all platforms (-0x0001 - -0x7FFF). In
* addition we'd like to give two layers of information on the error if
* possible.
*
* For that purpose the error codes are segmented in the following manner:
*
* 16 bit error code bit-segmentation
*
* 1 bit - Unused (sign bit)
* 3 bits - High level module ID
* 5 bits - Module-dependent error code
* 7 bits - Low level module errors
*
* For historical reasons, low-level error codes are divided in even and odd,
* even codes were assigned first, and -1 is reserved for other errors.
