[MERGE] Use ROOT_ID for dirstate and dirstate-tags working trees (bug #107168)

Hi all,

Dirstate trees don't produce produce repositories compatible with Bazaar
0.8 and later, because dirstate uses unique roots.

While I'm a great fan of unique roots, we intended these formats to be
network-compatible with earlier clients, so this patch causes Dirstate
trees to use TREE_ROOT when the repository doesn't support rich root
data.  This effectively limits it to --dirstate-with-subtree which is
already expected to be network-incompatible with older clients.
