It leverages the new hwaccel 1.2 features:

- get_buffer2 is never called
- the internal context is automatically initialized/deinitialized
Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

The current hwaccel is broken and cannot be fixed in a compatible
way. It will be deprecated and replaced with a new one.

It would reduce the boilerplate code users have to write.

This describes more accurately what this field is for.

This way each decoder does not have to do the same thing manually.

It will be useful in the following commits.
