When this .gitignore was added, lxdialog was an independent hostprogs-y.
Now that all objects in lxdialog/ are directly linked to mconf, the
lxdialog is no longer generated.

Pull Kconfig updates from Masahiro Yamada:
- rename lexer and parse files
- fix 'Save as' menu of xconfig
* tag 'kconfig-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
kconfig: fix 'Save As' menu of xconfig
kconfig: rename zconf.y to parser.y
kconfig: rename zconf.l to lexer.l
The 'Save As' menu of xconfig is not working; it always saves the
kernel configuration into the default file irrespective of the file
chosen in the dialog box.
The 'Save' menu always writes into the default file, but it would
make more sense to write into the file previously chosen by 'Load'
or 'Save As'.

If you run "make" in a pristine source tree, currently Kbuild will
start to build Kconfig to let it show the error message.
It would be more straightforward to check it in Makefile and let
it fail immediately.

I accidentally dropped '*' in the previous renaming patch.
Revive it so that 'make mrproper' can clean the generated files.

You do not have to use define ... endef for filechk_* rules.
For simple cases, the use of assignment looks cleaner, IMHO.
I updated the usage for scripts/Kbuild.include in case somebody
misunderstands the 'define ... endif' is the requirement.

Fix the following warning:

Currently, images.c is included by qconf.cc and gconf.c.
qconf.cc uses all of xpm_* arrays, but gconf.c only some of them.
Hence, lots of "... defined but not used" warnings are displayed
while compiling gconf.c
Splitting out images.c fixes the warnings.

Add "static" to functions that are locally used in gconf.c
This fixes some "no previous prototype for ..." warnings.

I want to compile each C file independently instead of including all
of them from zconf.y.
Split out confdata.c, expr.c, symbol.c, and preprocess.c .
These are low-hanging fruits.

All files in lxdialog/ are licensed under GPL-2.0+, and the rest are
under GPL-2.0. I added GPL-2.0 tags to test scripts in tests/.
Documentation/process/license-rules.rst does not suggest anything
about the flex/bison files. Because flex does not accept the C++
comment style at the very top of a file, I used the C style for
zconf.l, and so for zconf.y for consistency.

Commit 7a88488bbc ("[PATCH] kconfig: use gperf for kconfig keywords")
introduced gperf for the keyword lookup.
Then, commit bb3290d916 ("Remove gperf usage from toolchain") killed
the gperf use. As a result, the linear keyword search was left behind.
If we do not use gperf, there is no reason to have the separate table
of the keywords. Move all keywords back to the lexer.
I also refactored the lexer to remove the COMMAND and PARAM states.

To simplify the generated lexer, let the hand-made lexer update the
file name and line number for the parser.
I tested this with DEBUG_PARSE, and confirmed the same file names
and line numbers were dumped.

The lexer has conventionally associated kconf_id data with yylval
to carry additional information to the parser.
No token is relying on this any more.

T_ENDMENU, T_ENDCHOICE, T_ENDIF are the last users of kconf_id
associated with yylval. Refactor them to not use it.

In my understanding, special characters such as '.' and '/' are
supported in unquoted words to use bare file paths in the "source"
statement.
With the previous commit surrounding all file paths with double
quotes, we can drop this.

There is no grammatical ambiguity by using T_WORD for variables.
The parser can distinguish variables from symbols from the context.

Currently, the lexer returns T_ASSIGN for all of =, :=, and +=
associating yylval with the flavor.
I want to make the generated lexer as simple as possible. So, the
lexer should convert keywords to tokens without thinking about the
meaning.
= -> T_EQUAL
:= -> T_COLON_EQUAL
+= -> T_PLUS_EQUAL
Unfortunately, Kconfig uses = instead of == for the equal operator.
So, the same token T_EQUAL is used for assignment and comparison.
The parser can still distinguish them from the context.

For the keywords "modules", "defconfig_list", and "allnoconfig_y",
the lexer should pass specific tokens instead of generic T_WORD.
This simplifies both the lexer and the parser.
