test-transaction-safety: perform the test on a filelog This test previously checked the transaction safety of splitting the changelog. The changelog is a special case, with delayed/diverted writes and we will stop inlining it soon. So we keep testing that transaction is safe around inline on another revlog type : a filelog. Minor comestic adjustement will be done in the next changesets.

test: clarify test-parseindex offsets We will make this revlog non-inline, so we clarify the code to make sure it is simple to adjust the test later.

test: use more globing for perf timing Not sure why we kept the number here.

branching: merge with stable

statprof: handle `lineno == None` in more cases This continues the work from 972f3e5c94b8. We saw a crash on line 956 but I updated lots of other places as well.

branching: merge stable into default

add: don't attempt to add back removed files unless explicitly listed This fixes the bug demonstrated by the previous patch.

tests: show failure to `hg add -I` a dir->symlink transition

setup: try a non-pure version of the local Mercurial if the pure fails Things like `zstd` can make the pure version fails.

setup: make debug simpler by adding a `__repr__` to `hgcommand` This help when trying to debug this logic.

rhg: support rhg status --rev --rev

rust: add a utility function to merge ordered fallible iterators Adding a function merge_join_results_by, a version of itertools::merge_join_by that works on "fallible" iterators (iterators that can produce errors)

rhg: refactor hg status, make the display code usable for non-dirstate status

debugformat: speedup the "plain-cl-delta" check Checking every single revision is too slow, let's use a sampling approach.

templatekw: fix inconsistency of diffstat with diff.merge Previously, `-T'{diffstat}'` was giving stats from the diff against p1, regardless of whether `--config diff.merge=yes` is set. This was inconsistent with `log --patch` which is aware of that option.

util: move diff_parent from logcmdutil to diffutil This function will be used outside of the log command (in templatekw, used by hgweb, for which logcmdutil is not available). Let's move this function together with the rest of the diff-related utils instead.

logcmdutil: return structured diffstat data for json

cleanup: drop the `bytes` compatibility for attribute related function We can rely on the builtins directly now.

cleanup: turn `wrapfunction` deprecation warning into an error We could simply drop the check, but lets raise explicit error instead of suffering strange error in case of misuse.

cleanup: turn `wrappedfunction` deprecation warning into an error We could simply drop the check, but lets raise explicit error instead of suffering strange error in case of misuse.

cleanup: turn `pathsuboption` deprecation warning into an error We could simply drop the check, but lets raise explicit error instead of suffering strange error in case of misuse.

cleanup: drop deprecated config attribute on the revlog class This code was marked for deletion in the next cycle. We are now in the next cycle.

cleanup: drop `path.pushloc` deprecated since 6.5 This was scheduled for removal, let us remove it.

cleanup: drop `dirstate.is_changing_parent` deprecated since 6.5 This was scheduled for removal, let us remove it.
