Hi Ezequiel,

So far we've been using the .buf_finish hook to distinguish
decoder from encoder. This is unnecessarily obfuscated.
Moreover, we want to move the buf_finish, so use a cleaner
scheme to distinguish the driver decoder/encoder type.

FWIW I'd suggest removing the wrapper function entirely now - it makes
sense when the check itself is implemented in a weird and non-obvious
way, but a simple boolean flag named exactly what it means is already
about as clear as it can get.
Robin.
