That would be great. How about:
_gnutls_buffer_pop_prefix (gnutls_buffer_st * buf, size_t * data_size, int check,
uint8_t pfx_len = 32);
Or should we use "bool check" to make it more obvious?

If I'm trying to use datum->data I've got to drop const qualifier from "const void *
data" parameter. Right now I'm not sure if I should copy data or not.
