revlog: rename _chunkraw to _getsegmentforrevs() This completes our rename of internal revlog methods to distinguish between low-level raw revlog data "segments" and higher-level, per-revision "chunks." perf.py has been updated to consult both names so it will work against older Mercurial versions.
