tests: deal with "ls" vs "ls -A" difference on 2BSD derived systems ls on 2BSD derived systems historically defaults to -A for root, so use it unconditionally for consistent results.

tests: silence potential warnings about uname -o The option is not supported on the BSDs, but also not relevant as it is only used to detect msys.

evolve: remove unused divergenceflag and splitflag of MultipleSuccessorsError

evolve: consider all obsolete ancestors when finding new parent for orphan Both the old and the new logic have in common that the orphan changeset is moved to the tipmost successor of one or more ancestors of the orphan changeset. The previous logic considered only the first non-pruned ancestor of the orphan changeset. The new logic considers all obsolete ancestors of the orphan changeset. The logic in _possibledestination() had to be changed to be consistent with the new logic.

py3: fix debugstablerangecache

topic: provide cache to successorssets() in _singlesuccessor() Since we're using obsutil.successorssets() in a loop, it may help performance to have cache.

obslog: support --all with --no-graph

obslog: support --filternonlocal with --no-graph

obshistory: restructure templates a bit, drop default verb ("pruned") We always have a verb provided to the templates now, this should be fine.

obshistory: prepare data for displaymarkers() in a separate function

obshistory: make patchavailable() handle predecessors too

tests: make sure not to test the same thing twice A block under this one already tests obslog --no-graph with -f. Right now there's no difference in output, but maybe some day obslog --no-graph will actually support --filternonlocal.
