Upcoming patches will convert revlogs to use the compression engine APIs to perform all things compression. The yet-to-be-introduced APIs support a persistent "compressor" object so the same object can be reused for multiple compression operations, leading to better performance. In addition, compression engines like zstd may wish to tweak compression engine state based on the revlog (e.g. per-revlog compression dictionaries). A global and shared decompress() function will shortly no longer make much sense. So, we move decompress() to be a method of the revlog class. It joins compress() there. On the mozilla-unified repo, we can measure the impact of this change on reading performance: $ hg perfrevlogchunks -c ! chunk ! wall 1.932573 comb 1.930000 user 1.900000 sys 0.030000 (best of 6) ! wall 1.955183 comb 1.960000 user 1.930000 sys 0.030000 (best of 6) ! chunk batch ! wall 1.787879 comb 1.780000 user 1.770000 sys 0.010000 (best of 6 ! wall 1.774444 comb 1.770000 user 1.750000 sys 0.020000 (best of 6) "chunk" appeared to become slower but "chunk batch" got faster. Upon further examination by running both sets multiple times, the numbers appear to converge across all runs. This tells me that there is no perceived performance impact to this refactor.
