inotify: inotify.server.walk*() cleanup When not in root repo, if we meet a .hg, bail out. break was used, but return can be safely used instead: if we go through break then (top or not hginside) == False -> nothing is done after the for loop

inotify: inotify.server.walkrepodirs() simplify walking Do not 'yield tuple, boolean' to filter later on the boolean. Test the boolean first, and yield tuple only if needed.

inotify: inotify.server.walkrepodirs() simplify compute string concatenation only once

inotify: inotify.server.walk() simplify algorithm Do not yield (bool, tuple) in a subfunction and check later: 'if not bool: yield tuple'. Instead simplify so the tuple doesnt get yielded on the first time, to avoid systematic checks.

inotify: inotify.server.walk cleanups * Removing useless path computation * moving 'reporoot' computation down to the first call to avoid confusion with the parameter used in walkit()

revlog: add cache priming for reconstructing delta chains

revlog: use chunk cache to avoid rereading when splitting inline files

revlog: clean up the chunk caching code

revlog: use index to find index size

revlog: preread revlog .i file Smaller revlogs can be read with a single read, do it on open.
