There is two distinct enums both related to QPACK error management. The first one is dedicated to RFC defined code. The other one is a set of internal values returned by qpack_decode_fs(). There has been issues discovered recently due to the confusion between them. Rename internal values with the prefix QPACK_RET_*. The older name QPACK_ERR_* will be used in a future commit for the first enum.
