IMPALA-6389: Make '\0' delimited text files work

This is conflated a bit with the support work required to get
MySQL to run in the mini-cluster to support HMS, as Postgresql
simply rejects these table creations outright.

The basic idea is to specialize the class on whether row/tuple
delimiters are actually used, as the use case for sequence and
text files is quite different.  Unfortunately, that came out a
bit more ugly than I would have liked, as the class template
parameter infected all definitions.

Testing: Created a zero delimited table as described in the JIRA,
ran select * from tab_separated on the table.
