reachableroots: return list of revisions instead of set

Now we don't need a set of reachable revisions, and the caller wants a sorted
list of revisions, so constructing a set is just a waste of time.

  revset #0: 0::tip
  2) 0.002536
  3) 0.001598  63%

PyList_New() should set an appropriate exception on error, so we don't need
to call PyErr_NoMemory() manually.

This patch lacks error handling of PyList_Append() as it was before for
PySet_Add(). It should be fixed later.
