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

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 'shell' built-in only returns the first 256 bytes of the command's
output. In some cases, 'shell' is used to return a path; by bumping up
the buffer size to 4096 this lets us capture up to PATH_MAX.
The specific case where I ran into this was due to commit 1e860048c5
("gcc-plugins: simplify GCC plugin-dev capability test"). After this
change, we now use `$(shell,$(CC) -print-file-name=plugin)` to return
a path; if the gcc path is particularly long, then the path ends up
truncated at the 256 byte mark, which makes the HAVE_GCC_PLUGINS
depends test always fail.

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
INITRAMFS_SOURCE
LOCALVERSION
MODULE_SIG_HASH
MODULE_SIG_KEY
NDS32_BUILTIN_DTB
NIOS2_DTB_SOURCE
OPENRISC_BUILTIN_DTB
SOC_CANAAN_K210_DTB_SOURCE
SYSTEM_BLACKLIST_HASH_LIST

SYSTEM_TRUSTED_KEYS
TARGET_CPU
UNUSED_KSYMS_WHITELIST

When converting a modular kernel to a monolithic kernel, once the kernel
works without loading any modules, this helps to quickly disable all the
modules before turning off module support entirely.
Refactor conf_rewrite_mod_or_yes to a more general
conf_rewrite_tristates that accepts an old and new state.

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

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.

In Kconfig, like Python, you can enclose a string by double-quotes or
single-quotes. So, both "foo" and 'foo' are allowed.
The variable, "str", is used to remember whether the string started with
a double-quote or a single-quote because open/closing quotation marks
must match.
The name "str" is too generic to understand the intent. Rename it to
"open_quote", which is easier to understand. The type should be 'char'.

When one searches for a main menu item, links aren't created for it like
with the rest of the symbols.
This happens because we trace the item until we get to the rootmenu, but
we don't include it in the path of the item. The rationale was probably
that we don't want to show the main menu in the path of all items,
because it is redundant.
However, when an item has only the rootmenu in its path it should be
included, because this way the user can jump to its location.
Add a 'Main menu' entry in the 'Location:' section for the kconfig
items.
This makes the 'if (i > 0)' superfluous because each item with prompt
will have at least one menu in its path.

When merging configuration fragments, it might be of interest to
identify mismatches (redefinitions) programmatically. Hence add the
option -s (strict mode) to instruct merge_config.sh to bail out in
case any redefinition has been detected.
With strict mode, warnings are emitted as before, but the script
terminates with rc=1. If -y is set to define "builtin having
precedence over modules", fragments are still allowed to set =m (while
the base config has =y). Strict mode will tolerate that as demotions
from =y to =m are ignored when setting -y.
