py3: convert revlog stats to a dict of (bytes, int) pairs Py_DECREF(t) is replaced with Py_CLEAR(t) so that t is set to NULL once decrefed. Otherwise, it would be excessively decrefed if a subsequent PyBytes_FromString() failed.

rust: fix signature of rustlazyancestors_init() function Obviously, sizeof(int) != mem::size_of::<usize>() on amd64, though the argument would be passed in 64-bit register anyway.

tests: require SQLite 3.8.3+ as sqlitestore relies on "WITH" clause The test fails on gcc112 because the SQLite is too old. https://sqlite.org/changes.html#version_3_8_3

relnotes: various tweaks for release notes Stop filtering out commits that are expected to be covered by releasenotes extension: now we want two lists, one for WhatsNew and one for ReleaseX.Y. Use `only(stoprev, startrev)` to make `relnotes -h` output be actually true about what revisions are included. More filter rules, mostly obvious. More classifying rules to have less things in "unsorted". Looks like nargs=1 was just making args.startrev and args.stoprev be lists for no reason. BC and API sections are renamed to what we're using on the WhatsNew page, and also just skipped if empty.

delta: skip "empty delta" optimisation for non-general case (issue6006) Non-general delta repository cannot delta against anything than prev. So even if the delta to prev is empty we should use it. This is similar to the change made in bafa1c4bb7a8. Differential Revision: https://phab.mercurial-scm.org/D5201

narrow: fix copies._fullcopytracing() narrowspec filtering in graft case I broke this too in 707c3804e607 (narrow: move copies overrides to core, 2018-09-28). Hopefully I'm done fixing things broken by that commit now. Differential Revision: https://phab.mercurial-scm.org/D5213

tests: demonstrate broken copies._fullcopytracing() Turns out copies._fullcopytracing() was also broken. Differential Revision: https://phab.mercurial-scm.org/D5212

narrow: make copies.pathcopies() filter with narrowspec again I broke this in 707c3804e607 (narrow: move copies overrides to core, 2018-09-28). Differential Revision: https://phab.mercurial-scm.org/D5203
