Subject: kconfig: autogenerated config_is_xxx macro

this will allow to use to use

	if(config_is_xxx())
	if(config_is_xxx_module())

in the code instead of

	#ifdef CONFIG_xxx
	#ifdef CONFIG_xxx_MODULE

and now let the compiler remove the non usefull code and not the
pre-processor

as done in the mach-types for arm as exmaple

Subject: kconfig: Only generate config_is_xxx for bool and tristate options

For strings and integers, the config_is_xxx macros are useless and
sometimes misleading:

  #define CONFIG_INITRAMFS_SOURCE ""
  #define config_is_initramfs_source() 1

Subject: kconfig/gconf: kill deadcode

The only call site of renderer_toggled() has been commented out since Apr. 2003,
as per Linus' Linux history repository:

 commit e7f67eb3c0570aa50c1cc0707b478a6d93bdc255
 Author: Roman Zippel <zippel@linux-m68k.org>
 Date:   Fri Apr 4 04:18:05 2003 -0800

    [PATCH] gconf update

    A gconf update by Romain Li<C3><A9>vin <roms@tilp.info>
    - fixed bug when double-clicking for changing value.
    - expand row when enabling a row with a submenu.
    - various bug fixes

As this result in a warning:

scripts/kconfig/gconf.c:891:13: warning: 'renderer_toggled' defined but not used

just nuke that code.

As the `gconf' frontend is un-maintained, go the easy way by silencing
the "warning: no previous prototype for '<fn>'" warnings.

Subject: kconfig: do not overwrite symbol direct dependency in assignment

Considering the following configuration:

config F
    bool "F"

choice AB
    bool "AB"
config A
    bool "A"
config B
    bool "B"
endchoice

if A
config D
    bool
    default y if F
    select E
config E
    bool "E"
endif

if B
config D
    bool
    default y if F
    select E
config E
    bool "E"
endif

The following configuration:

 CONFIG_F=y
 CONFIG_A=y
 # CONFIG_B is not set
 CONFIG_D=y
 CONFIG_E=y

emits a spurious warning:

(D) selects E which has unmet direct dependencies (B)

If a symbol appears in two different branch of the tree, it should inherit the
dependency of both parent, not just the last one.

Subject: kconfig: introduce specialized printer

Make conf_write_symbol() grammar agnostic to be able to use it from different
code path. These path pass a printer callback which will print a symbol's name
and its value in different format.

conf_write_symbol()'s job become mostly only to prepare a string for the
printer. This avoid to have to pass specialized flag to generic
functions

Subject: kconfig/conf: reduce the scope of `defconfig_file'

This variable is not used outside of main() so there is not much reason keeping
it global. Ensure it is initialized as gcc has no way to know that normal
execution path expect only one option switch to be given on the command line
(except when we request help). As a result, we always initialize
`defconfig_file' before using it.

Subject: kconfig/nconf: use the generic menu_get_ext_help()

nconf is the only front-end which does not use this helper, but prefer
to copy/paste the code. The test wrt. menu validity added in this
version of the code is bogus anyway as an invalid menu will get
dereferenced a few line below by calling menu_get_prompt().

For now, convert nconf to use menu_get_ext_help(), as do every other
front-end. We will deals with menu validity checks properly in a
separate commit.

Subject: kconfig/nconf: prevent segfault on empty menu

nconf does not check the validity of the current menu when help is
requested (with either <F2>, '?' or 'h'). This leads to a NULL pointer
dereference when an empty menu is encountered.

The following reduced testcase exposes the problem:

config DEP
        bool

menu "FOO"

config BAR
        bool "BAR"
        depends on DEP

endmenu

Issue will happen when entering menu "FOO" and requesting help.

nconf is the only front-end which do not filter the validity of the
current menu. Such filter can not really happen beforehand as other key
which does not deals with the current menu might be entered by the user,
so just bails out earlier if we encounter an invalid menu.

After the test

the variable `submenu' can _not_ be NULL, so do not test for this

Subject: kconfig: fix missing "0x" prefix from S_HEX symbol in autoconf.h

The specialized printer for headers (espectially autoconf.h) is missing
fixup code for S_HEX symbol's "0x" prefix. As long as kconfig does not
warn for such missing prefix, this code is needed. Fix this.

In the same time, fix some nits in `header_print_symbol()'.

Subject: kconfig: Introduce IS_ENABLED(), IS_BUILTIN() and IS_MODULE()

Replace the config_is_*() macros with a variant that allows for grepping
for usage of CONFIG_* options in the code. Usage:

  if (IS_ENABLED(CONFIG_NUMA))

or

  #if IS_ENABLED(CONFIG_NUMA)

The IS_ENABLED() macro evaluates to 1 if the argument is set (to either 'y'
or 'm'), IS_BUILTIN() tests if the option is 'y' and IS_MODULE() test if
the option is 'm'. Only boolean and tristate options are supported.
