Added tag 2.0-rc for changeset 384082750f2c

merge default into stable for 2.0 code freeze

rebase: simplify check for orphaned descendants

rebase: simplify set generation

rebase: add --rev option to rebase This option allow a strict set of revision to be specified instead of using -s or -b. Rebase will refuse start if striping rebased changeset will strip non rebased changeset. Rebase will refuse to work on set with multiple root.

rebase: allow revsets for source and base args

revset: fix %r handling in formatspec

rebase: use revset as soon as possible in internal logic The buildstate function now take a set of revs. Logic related to --source and --base option have been moved in the main rebase function. In the process this fixes a bug where the wrong source changeset might be pick. This explain the changes in hgext/rebase.py

revset: add %r for embedded revset support to formatspec This allows folding external revsets or lists of revsets into a revset expression. Revsets are pre-parsed for validity so that syntax errors don't escape.

revert: warn that subrepos cannot be reverted (tests added by mpm)
