\brief This function initializes the specified Poly1305 context.

             It must be the first API called before using

             It is usually followed by a call to
             \c mbedtls_poly1305_starts(), then one or more calls to
             \c mbedtls_poly1305_update(), then one call to
             \c mbedtls_poly1305_finish(), then finally
             \c mbedtls_poly1305_free().

\param ctx The Poly1305 context to initialize. This must not be \c NULL.
