[PATCH 01/27] kconfig: fix file name and line number of warn_ignored_character()

From: Masahiro Yamada
Date: Tue Dec 11 2018 - 06:02:50 EST

Currently, warn_ignore_character() displays invalid file name and
line number.

The lexer should use current_file->name and yylineno, while the parser
should use zconf_curname() and zconf_lineno().

This difference comes from that the lexer is always going ahead
of the parser. The parser needs to look ahead one token to make a
shift/reduce decision, so the lexer is requested to scan more text
from the input file.

This commit fixes the warning message from warn_ignored_character().

[Test Code]

----(Kconfig begin)----
-----(Kconfig end)-----


Before the fix:

<none>:0:warning: ignoring unsupported character '/'

After the fix:

Kconfig:1:warning: ignoring unsupported character '/'
