bundle: remove 'op' argument from applybundle() No callers pass in an operation.

test-rebase-conflicts: add a test case about turning obsstore on and off Turning obsstore and allowunstable on, rebase will skip the "can't remove original changesets with unrebased descendants" check. Then rebase could be interrupted (merge conflict), and the user has a chance to turn off obsstore. If rebase continues, the current code may strip irrelevant commits (in the test case added, "C" got stripped unexpectedly). The test case reproduces issue5606. It will be fixed by the "multidest" rebase refactoring being reviewed. The test case itself is relatively separate from the rebase refactoring, therefore sent separately hoping to reduce the number of patches of the main rebase series.

strip: include phases in bundle (BC) Before this patch, unbundling a stripped changeset would make it a draft (unless the parent was secret). This meant that one would lose phase information when stripping and unbundling secret changesets. The same thing was true for public changesets. While stripping public changesets is generally rare, it's done frequently by e.g. the narrowhg extension. We also include the phases in the temporary bundle, just in case stripping were to fail after that point, so the user can still restore the repo including phase information. Before this patch, the phases were left untouched during the bundling and unbundling of the temporary bundle. Only at the end of the transaction would phasecache.filterunknown() be called to remove phase roots that were no longer valid. We now need to call that also after the first stripping, i.e. before applying the temporary bundle. Otherwise unbundling the temporary bundle will cause a read of the phase cache which has stripped changesets in the cache and that fails. Like with obsmarkers, we unconditionally include the phases in the bundle when stripping (when using bundle2, such as when generaldelta is enabled). The reason for doing that for strip but not for bundle is that strip bundles are not meant to be shared outside the repo, so we don't care as much about compatibility.

bundle: add config option to include phases This adds an experimental.bundle-phases config option to include phase information in bundles. As with the recently added support for bundling obsmarkers, the support for bundling phases is hidden behind the config option until we decide to make a bundlespec v3 that includes phases (and obsmarkers and ...). We could perhaps use the listkeys format for this, but that's considered obsolete according to Pierre-Yves. Instead, we introduce a new "phase-heads" bundle part. The new part contains the phase heads among the set of bundled revisions. It does not include those in secret phase; any head in the bundle that is not mentioned in the phase-heads part is assumed to be secret. As a special case, an empty phase-heads part thus means that any changesets should be added in secret phase. (If we ever add a fourth phase, we'll include secret in the part and we'll add a version number.) For now, phases are only included by "hg bundle", and not by e.g. strip and rebase.
