branching: merge stable into default for 6.9 cycle

Added signature for changeset 11f41248595b

Added tag 6.8 for changeset 11f41248595b

relnotes: add 6.8

test-check: don't report distutils as a local import On python 3.12 this is wrongly reported as a local import. So we adjust the checker to avoid it.

Backed out changeset f28c52a9f7b4 This backout and the previous are due to a large performance regression detected in repositories with a lot of obsmarkers when performing a clone. A better fix will come along at the start of the next cycle.

rust: use `cpython` 0.7.2 crate to add support for Python 3.12 This will give us more headroom until we can migrate to PyO3 some day.

revbranchcache: disable mmap access by default The revbranchcache can be truncated (if some part of it is detected as invalid). Using mmap on file we truncate is not an option at access to truncated part would result in a SIGBUS signal. So we disable the mmap by default until we fix this issue.
