rust-dirstate: add "dirs" Rust implementation
Following the work done in d1786c1d34fa and working towards the goal of a
complete Rust implementation of the dirstate, this rewrites the `dirs` class.
There is already a C implementation, which relies heavily on CPython hacks and
protocol violations for performance, so I don't expect this to perform as well
for now, as this is very straight-forward code.
The immediate benefits are new high-level documentation and some unit tests.
