util: compression APIs to support revlog decompression

Previously, compression engines had APIs for performing revlog
compression but no mechanism to perform revlog decompression. This
patch changes that.

Revlog decompression is slightly more complicated than compression
because in the compression case there is (currently) only a single
engine that can be used at a time. However for decompression, a
revlog could contain chunks from multiple compression engines. This
means decompression needs to map to multiple engines and
decompressors. This functionality is outside the scope of this patch.
But it drives the decision for engines to declare a byte header
sequence that identifies revlog data as belonging to an engine and
an API for obtaining an engine from a revlog header.
