Copy a secp256k1 context object (into dynamically allocated memory).
This function uses malloc to allocate memory. It is guaranteed that malloc is
called at most once for every call of this function. If you need to avoid dynamic
memory allocation entirely, see the functions in secp256k1_preallocated.h.
