dirstate-entry: turn dirstate tuple into a real object (like in C)

With dirstate V2, the stored information and actual format will change. This mean we need to start an a better abstraction for a dirstate entry that a tuple directly accessed.

By chance, the C code is already doing this and pretend to be a tuple. So it
should be fairly easy. We start with turning the tuple into an object, we will
slowly migrate the dirstate code to no longer use the tuple directly in later
changesets.

Differential Revision: https://phab.mercurial-scm.org/D10949

This file tests the behavior of run-tests.py itself.

Avoid interference from actual test env:

  $ . "$TESTDIR/helper-runtests.sh"

Smoke test with install
============
  $ "$PYTHON" $TESTDIR/run-tests.py $HGTEST_RUN_TESTS_PURE -l
  running 0 tests using 0 parallel processes 
  
  # Ran 0 tests, 0 skipped, 0 failed.

Define a helper to avoid the install step
=============
  $ rt()
  > {
  >     "$PYTHON" $TESTDIR/run-tests.py --with-hg=`which hg` -j1 "$@"
  > }
