scanner: use %option never-interactive
It looks like Flex has a "never-interactive" option which does
what the batch option should be doing: it removes the use of
isatty.
Historically, it was an %option only with no corresponding
command-line option; newer Flex has a --never-interactive
command line option also.
The batch option actually makes very little difference in the
output. If never-interactive is used, then the batch option
makes no difference.
* parser.l (%option): Add never-interactive option, remove
batch.
(VER, FLEX_VER, YY_NO_UNISTD_H, isatty, no_isatty): Remove all
these macros: under the never-interactive option, there are
no isatty calls and no inclusion of <unistd.h>.
