build: build deb/rpm independently on config/extensions in the host system Reverts 5aac617a028d and replaces it with a more general solution. - works for both rpm and deb - sidesteps eventual problems with local extensions that have nothing to do with the build process (hg-git, for example, fails with version 4.4 because dedab036215d removed peerrepository, and hg-git still uses it as of 0.8.9)

config: also gather effect-flags on experimental.evolution Effect-flags config was in flight while the previous evolve config renaming was written. Now that both landed, gather effect-flags in experimental.evolution like the others evolve-related configurations. Differential Revision: https://phab.mercurial-scm.org/D1197

obsfate: rename obsfate into obsolete in default mapfile Like the previous patch, replace obsfate by obsolete in default mapfile. Differential Revision: https://phab.mercurial-scm.org/D1190

obsfate: rename obsfate into obsolete in changeset_printer Yuja's comment on the original obsfate about how we would translate obsfate and the recent discussions about exposing users to new concepts and names lead have led me to think that 'obsfate' should be treated as internal jargon. End- users should not be aware of obsfate, so we replace 'obsfate' by 'obsolete' in changeset_printer. It will be easier to understand for end-users, easier to translate and closer to the original Evolve obsfate output. I'm aware it's extremely late in the cycle but I think it's an UX improvement for the end-users. Differential Revision: https://phab.mercurial-scm.org/D1189

sparse-read: ignore trailing empty revs in each read chunk An empty entry in the revlog may happen for two reasons: - when the file is empty, and the revlog stores a snapshot; - when there is a merge and both parents were identical. `hg debugindex -m | awk '$3=="0"{print}' | wc -l` gives 1917 of such entries in my clone of pypy, and 113 on my clone of mercurial. These empty revision may be located at the end of a sparse chain, and in some special cases may lead to read relatively large amounts of data for nothing.

fsmonitor: use nonnormalset from dirstatemap `dirstate._nonnormalset` has been moved to `dirstate._map.nonnormalset` by 60927b19ed65 (dirstate: move nonnormal and otherparent sets to dirstatemap) and is guaranteed to be existed. Let's update fsmonitor code to use the new `nonnormalset`. Thix fixed a perf regression that slows down `hg status` by 0.5 seconds in one of our production repos.
