dirstate: add dirstatetuple to create dirstate values

Upcoming patches will switch away from using Python tuples for dirstate values
in compiled builds.  Make that easier by introducing a variable called
dirstatetuple, currently set to tuple. In upcoming patches, this will be set to
an object from the parsers module.
