cmdutil: add origbackuppath helper

discovery: pass pushop to _nowarnheads Previously, we passed only enough information to _nowarnheads to perform the old calculation. However, extensions may want to use more information in this calculation. Now that pushop is extensible, extensions will often want access to the additional fields they have added to the pushop, so pass that through. Specifically, the remotenames extension will use this information to allow pushing new heads that are bookmarked without requiring --force.

exchange: pass pushop to discovery.checkheads Previously, we passed a bunch of parameters to discovery.checkheads, but all of the arguments can be fetched out of pushop, which may contain a lot more useful information for extensions now that pushop is extensible.

share: wrap bmstore._writerepo for transaction sensitivity (issue4940) 46dec89fe888 made 'bmstore.write()' transaction sensitive, to restore original bookmarks correctly at failure of a transaction. For example, shelve and unshelve imply steps below: before 46dec89fe888: 1. move active bookmark forward at internal rebasing 2. 'bmstore.write()' writes updated ones into .hg/bookmarks 3. rollback transaction to remove internal commits 4. restore updated bookmarks manually after 46dec89fe888: 1. move active bookmark forward at internal rebasing 2. 'bmstore.write()' doesn't write updated ones into .hg/bookmarks (these are written into .hg/bookmarks.pending, if external hook is spawn) 3. rollback transaction to remove internal commits 4. .hg/bookmarks should be clean, because it isn't changed while transaction running: see (2) above But if shelve or unshelve is executed in the repository created with "shared bookmarks" ("hg share -B"), this doesn't work as expected, because: - share extension makes 'bmstore.write()' write updated bookmarks into .hg/bookmarks of shared source repository regardless of transaction activity, and - intentional transaction failure at the end of shelve/unshelve doesn't restore already updated .hg/bookmarks of shared source This patch makes share extension wrap 'bmstore._writerepo()' instead of 'bmstore.write()', because the former is used to actually write bookmark changes out.

test: use generaldelta in 'test-clonebundle.t' Using generaldelta has effects on the generated bundle.

test: use generaldelta in 'test-ssh.t' This has effects on the capabilities string.

test: use generaldelta in 'test-ssh-bundle1.t' This has effect on the capabilities string.

test: use generaldelta in 'test-strip.t' This has minor effects on test output.

test: use generaldelta in 'test-rebase-newancestors.t' This has some minor effects on test output.

test: use general delta for 'test-commit-amend.t' Using general delta introduces harmless changes to some of the test output.

test: wider matching in 'test-clone-r.t' The test is already somewhat resistant to changes from general delta. We make it wider to catch expected differences.

test: use generaldelta in 'test-bundle-type.t' Generaldelta changes some of the default targets for 'hg bundle'. All cases are already properly tested but some ambiguous specifications are affected.

test: use generaldelta in 'test-patchbomb.t' Using generaldelta changes the default type of bombed bundle.

test: use generaldelta for test-bundle.t This impacts tests of the 'packed' feature. We can safely accept the new output because the 'v1' format is not restricted to old revlog format, the requirements are properly advertised to the client.

test: use generaldelta in 'test-rebase-conflict.t' Doing this has some minor impacts on test output since the rebase backup bundle moves to bundle2.

tests: test generaldelta configuration in test-init.t We turn the feature on for the whole test and test that it can properly be disabled through the config.

test: enable generaldelta early in 'test-treemanifest.t' Having generaldelta on results in minor test output changes (as we are staring at the revlog).

test: enable generaldelta in 'test-copy.t' Doing so has a minimal impact on the test.

test: enable generaldelta in 'test-debugcommand.t' The test logic is not affected by generaldelta, so we move it to generaldelta early. Some of the fuzzy matching had to be extended to cover "delta".

test: use generaldelta in test-manifestv2.t Generaldelta and bundle2 have no real influence on this test. So we can safely switch it early.

test: explicitly use generaldelta in 'test-rebase-mq-skip.t' This induces some trivial changes in the tests. This happen in its own changeset for clarity purposes.

test: using generaldelta in 'test-lfconvert.t' This leads to a harmless test change.

test: enforce generaldelta format with the right option The option that will become true by default is now 'usegeneraldelta' We have to adjust the change made in b75fed55f6dc to actually achieve its goal.
