[ Upstream commit ee06a3ef7e3cddb62b90ac40aa661d3c12f7cabc ]
Prior to commit 5ee5465940 ("kconfig: change sym_change_count to a
boolean flag"), the conf_updated flag was set to the new value *before*
calling the callback. xconfig's save action depends on this behaviour,
because xconfig calls conf_get_changed() directly from the callback and
now sees the old value, thus never enabling the save button or the
shortcut.
Restore the previous behaviour.

Currently, "# end of ..." is inserted when the menu goes back to its
parent.
Hence, an empty menu:
menu "Foo"
endmenu
... ends up with unbalanced menu comments, like this:
#
# Foo
#
Let's close the menu comments properly:
#
# Foo
#
# end of Foo

As David Laight pointed out, there is not much point in calling

When the KCONFIG_AUTOCONFIG is specified (e.g. export \
KCONFIG_AUTOCONFIG=output/config/auto.conf), the directory of
include/config/ will not be created, so kconfig can't create deps
files in it and auto.conf can't be generated.

The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:
ACPI_CUSTOM_DSDT_FILE
ARC_BUILTIN_DTB_NAME
ARC_TUNE_MCPU
BUILTIN_DTB_SOURCE
CC_IMPLICIT_FALLTHROUGH
CC_VERSION_TEXT
CFG80211_EXTRA_REGDB_KEYDIR
EXTRA_FIRMWARE
EXTRA_FIRMWARE_DIR
EXTRA_TARGETS
H8300_BUILTIN_DTB

SYSTEM_TRUSTED_KEYS

I checked them one by one, and fixed up the code where necessary.

If this function fails to touch a dummy header due to missing parent
directory, then it creates it and touches the file again.
This was needed because CONFIG_FOO_BAR was previously tracked by
include/config/foo/bar.h. (include/config/foo/ may not exist here)
This is no longer the case since commit 0e0345b77a ("kbuild: redo
fake deps at include/config/*.h"); now all the fake headers are placed
right under include/config/, like include/config/FOO_BAR.
Do not try to create parent directory, include/config/, which already
exists.

The if ... else inside the for-loop is unneeded because one empty
line is placed after printing the last element of deps_config.
Currently, all errors in conf_write_dep() are ignored. Add proper
error checks.
Rename it to conf_write_autoconf_cmd(), which is more intuitive.

Now that sym_escape_string_value() is only used in confdata.c
it can be a 'static' function.
Rename it escape_string_value() because it is agnostic about

We can reuse __print_symbol() helper to print symbols for listnewconfig.
Only the difference is the format for "n" symbols.
This prints "CONFIG_FOO=n" instead of "# CONFIG_FOO is not set".

I do not think 'struct conf_printer' is so useful.

All the call sites of conf_write_heading() pass NULL to the third
argument, and it is not used in the function.
Also, the print_comment hooks are doing much more complex than
needed.
Rewrite the code.

sym_escape_string_value() returns a malloc'ed memory, but as
(const char *). So, it must be casted to (void *) when it is free'd.
This is odd.
The return type of sym_escape_string_value() should be (char *).
I exploited that free(NULL) has no effect.

sym_change_count has no good reason to be 'int' type.
sym_set_change_count() compares the old and new values after casting
both of them to (bool). I do not see any practical diffrence between
sym_set_change_count(1) and sym_add_change_count(1).
Use the boolean flag, conf_changed.

"defconfig_list" is a weird option that defines a static symbol that
declares the list of base config files in case the .config does not
exist yet.
This is quite different from other normal symbols; we just abused the
"string" type and the "default" properties to list out the input files.
They must be fixed values since these are searched for and loaded in
the parse stage.
It is an ugly hack, and should not exist in the first place. Providing
this feature as an environment variable is a saner approach.
