/**
* \brief EC implementation "m62" (specialised code) for Curve25519.
*
* This implementation uses custom code relying on multiplication of
* integers up to 62 bits, with a 124-bit result. This implementation is
* defined only on platforms that offer the 64x64->128 multiplication
* support; use `br_ec_c25519_m62_get()` to dynamically obtain a pointer
* to that implementation. Due to the specificities of the curve
* definition, the following applies:
*
* - `muladd()` is not implemented (the function returns 0 systematically).
* - `order()` returns 2^255-1, since the point multiplication algorithm
* accepts any 32-bit integer as input (it clears the top bit and low
* three bits systematically).
