evolve: be more complete about copying extra from old revisions For 'hg evolve' we want to copy all extra-level metadata except for branch. This keeps the experimental topics extension from getting obliterated by evolve runs. Many hashes in tests changed due to some extra data coming along for the ride in various places, but no functionality that was tested. It's plausible that this copies too much metadata - maybe we should be dropping rebase_src or convert_revision as well. Right now no tools do that, so I'm biasing towards preserving everything except branch when copying metadata for now.

evolve: ignore ui argument passed to help loader The API changed at Mercurial e0c572d4d112.

directaccess: inspect trees of len() > 3 Previously, when inspecting revset AST's we'd only traverse down the tree if it was length 3 ([op, left, right]). In some situations, like 'or' the tree node will be greater than length 3 ([op, first, second, ..., nth]). So we need to traverse all the parts of the node to catch all the symbols.

debugobsconvert: make sure obsstore is loaded before version comparison hg 44918682093f delays loading obsstore, so we have to access _all to get the correct store version.
