Move CR filtering from tabFilter to the readers.

The readers previously assumed that CRs had been filtered
from the input.  Now we strip the CRs in the readers themselves,
before parsing.  (The point of this is just to simplify the
parsers.)

Shared now exports a new function `crFilter`. [API change]
And `tabFilter` no longer filters CRs.
