revlog: apply compression mode while reading sidedata

now. Future changeset will start using some.

revlog: implement a "default compression" mode
The revlog docker is now storing a default compression engine. When a chunk use
that compression, a dedicated mode is used in the revlog entry and we can
directly route it to the right decompressor.
We should probably make PLAIN and DEFAULT mode the only available mode for
revlogv2, but this is something for later.
