add dirstate debugging commands
As I've played with various different merges and more recently
rawcommit, I've found the following patch to be very very helpful in
figuring out whether the dirstate is being left in a consistent or
inconsistent state with respect to the current manifest.
I attempted to deduce the invariants that were assumed by the current
code, and then check it in this code.
I may or may not have captured the design intent in this check; if not,
I'd be very happy to hear more clearly what was intended, so that I can
write tests to that expectation.
Anyway, here's the patch. Not sure if it's a good idea to commit it to
the mainline, or just leave it as a debugging aid. I attempted to
package it so that it doesn't interfere with normal usage.
