/// API: user_profile/user_profile_init
///
/// Constructs a user profile config object and sets a pointer to it in `conf`.
///
/// When done with the object the `config_object` must be destroyed by passing the pointer to
/// config_free() (in `session/config/base.h`).
///
/// Declaration:
/// ```cpp
/// INT user_profile_init(
///     [out]   config_object**         conf,
///     [in]    const unsigned char*    ed25519_secretkey,
///     [in]    const unsigned char*    dump,

///     [out]   char*                   error
/// );
/// ```
///
/// Inputs:
/// - `conf` -- [in] Pointer to the config object
/// - `ed25519_secretkey` -- [in] must be the 32-byte secret key seed value.  (You can also pass the
/// pointer to the beginning of the 64-byte value libsodium calls the "secret key" as the first 32
/// bytes of that are the seed).  This field cannot be null.
/// - `dump` -- [in] if non-NULL this restores the state from the dumped byte string produced by a
/// past instantiation's call to `dump()`.  To construct a new, empty profile this should be NULL.
/// - `dumplen` -- [in] the length of `dump` when restoring from a dump, or 0 when `dump` is NULL.
/// - `error` -- [out] the pointer to a buffer in which we will write an error string if an error
/// occurs; error messages are discarded if this is given as NULL.  If non-NULL this must be a
/// buffer of at least 256 bytes.
///
/// Outputs:
/// - `int` -- Returns 0 on success; returns a non-zero error code and write the exception message
/// as a C-string into `error` (if not NULL) on failure.
