Fix the tclsqlite.c TCL interface module so that it works with both Tcl8 and

Tcl9.  Make changes across the TCL-based test harness to enable SQLite to
be tested with either Tcl8 or Tcl9.  Get the --with-tcl= argument on the
configure script working. Testing changes only - no changes to the SQLite core.
I believe the previous merge attempt didn't work because of errors in the
merge itself, not because of faults in the code.  Trying again...
