gst/parse/parse.l: Use "%option never-interactive" to prevent useless calls to isatty() on every input when parsing. ...

Browse source 
Original commit message from CVS:
* gst/parse/parse.l:
Use "%option never-interactive" to prevent useless calls to isatty()
on every input when parsing. Also use "%option noinput" to not define
the static input/yyinput functions which we don't use anyway. This
removes a compiler warning with gcc 4.3 and saves some bytes in the
library.
* gst/parse/lex._gst_parse_yy.pre.c:
Regenerated for the above change.
