Add int return values to RIPEMD-160 function calls
The following function calls are being deprecated to introduce int
return values.
* mbedtls_ripemd160()
* mbedtls_ripemd160_starts()
* mbedtls_ripemd160_update()
* mbedtls_ripemd160_finish()
* mbedtls_ripemd160_process()
The return codes can be used to return error values. This is important
when using hardware accelerators.
