This function will register a new extension type. The
extension will remain registered until
gnutls_global_deinit() is called. If the extension type is
already registered then GNUTLS_E_ALREADY_REGISTERED will be
returned.

Each registered extension can store temporary data into the
gnutls_session_t structure using gnutls_ext_set_data(), and
they can be retrieved using gnutls_ext_get_data().

This function is not thread safe.

GNUTLS_E_SUCCESS on success, otherwise a negative error
code.
