On the 'move-tracking-2' branch: Keep track of new EIDs assigned with atransaction, and only convert them to permanent EIDs at commit time.This allows us to add elements in a txn based on an old revision, and then'update' the txn to be based on a newer revision, and the EIDs added in thenewer revision will not clash with the EIDs added in the txn. (This 'update'could be either a client-side WC update or the automatic rebase-on-commit.)* subversion/libsvn_delta/editor3e.c (VALID_EID): Adjust for local EIDs being negative.* subversion/include/private/svn_branch.h, subversion/libsvn_delta/branch.c (svn_branch_revision_root_t): Document that 'first_eid' holds less than zero for transaction-local EIDs. (svn_branch_txn_new_eid): Rename from 'svn_branch_revision_root_new_eid'. Allocate negative EIDs instead of positive EIDs. (branch_finalize_eids, svn_branch_txn_finalize_eids): New. (svn_branch_map_add_subtree): Track the rename.* subversion/libsvn_delta/compat3e.c (editor3_new_eid): Track the rename. (editor3_alter): Track the rename. Adjust for local EIDs being negative. (editor3_complete): Finalize the txn EIDs before committing.* subversion/libsvn_delta/element.c (svn_element_payload_invariants): Adjust for local EIDs being negative.* subversion/svnmover/svnmover.c (do_branch): Track the rename.
