dirstate: add explicit methods for querying directories (API)
The set-like object returned by dirstate.dirs may be difficult for other
implementations of the dirstate to provide, and is unnecessary as it is
only ever used for __contains__. Instead, provide an explicit method for
testing for a directory.
.. api::
dirstate no longer provides a `dirs()` method. To test for the existence of
a directory in the dirstate, use `dirstate.hasdir(dirname)`.
