Remove unused "ignore" field in widl structures

[Dan Hipschman]

This field is superfluous:

[widl]$ find -name "*.[chly]" | xargs fgrep -n ignore
./parser.y:1049:  t->ignore = parse_only;
./parser.y:1126:  f->ignore = parse_only;
./widltypes.h:208:  int ignore, is_const, sign;
./widltypes.h:238:  int ignore, idx;
./parser.tab.c:3841:  t->ignore = parse_only;
./parser.tab.c:3918:  f->ignore = parse_only;

This cleans up widl a bit by removing it.

ChangeLog:
* Remove unused "ignore" field in type_t and func_t structures
