bb3290d916 Remove gperf usage from toolchain
It turns out that gperf-3.1 changed types in the generated code in ways
that aren't even trivially detectable without having to generate a test-file.

It's just not worth using tools and libraries from clowns that don't
understand or care about compatibility.  So get rid of gperf.

ff85a1a80e kconfig: Check for libncurses before menuconfig
There is a check and a nice user-friendly message when the curses
library is not present on the system and the user wants to do "make
menuconfig". It doesn't get issued, though. Instead, we fail the build
when mconf.c doesn't find the curses.h header:

    HOSTCC  scripts/kconfig/mconf.o
  In file included from scripts/kconfig/mconf.c:23:0:

   #include CURSES_LOC
                      ^
  compilation terminated.

Make that check a prerequisite to mconf so that the user sees the error
message instead:

  $ make menuconfig
   *** Unable to find the ncurses libraries or the
   *** required header files.
   *** 'make menuconfig' requires the ncurses libraries.

cb77f0d623 scripts: Switch to more portable Perl shebang
The default NetBSD package manager is pkgsrc and it installs Perl
along other third party programs under custom and configurable prefix.
The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.

This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.

This change switches -w option passed to the executable with more
modern "use warnings;" approach. There is no functional change to the
default behavior.

While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?).

79e51b5c2d kconfig/nconf: Fix hang when editing symbol with a long prompt
Currently it is impossible to edit the value of a config symbol with a
prompt longer than (terminal width - 2) characters.  dialog_inputbox()
calculates a negative x-offset for the input window and newwin() fails
as this is invalid.  It also doesn't check for this failure, so it
busy-loops calling wgetch(NULL) which immediately returns -1.

The additions in the offset calculations also don't match the intended
size of the window.

Limit the window size and calculate the offset similarly to
show_scroll_win().

237e3ad0f1 Kconfig: Introduce the "imply" keyword
The "imply" keyword is a weak version of "select" where the target
config symbol can still be turned off, avoiding those pitfalls that come
with the "select" keyword.

This is useful e.g. with multiple drivers that want to indicate their
ability to hook into a secondary subsystem while allowing the user to
configure that subsystem out without also having to unset these drivers.

Currently, the same effect can almost be achieved with:

config DRIVER_A
	tristate

config DRIVER_B
	tristate

config DRIVER_C
	tristate

config DRIVER_D
	tristate

[...]

config SUBSYSTEM_X
	tristate
	default DRIVER_A || DRIVER_B || DRIVER_C || DRIVER_D || [...]

This is unwieldy to maintain especially with a large number of drivers.
Furthermore, there is no easy way to restrict the choice for SUBSYSTEM_X
to y or n, excluding m, when some drivers are built-in. The "select"
keyword allows for excluding m, but it excludes n as well. Hence
this "imply" keyword.  The above becomes:

config DRIVER_A
	tristate
	imply SUBSYSTEM_X

config DRIVER_B
	tristate
	imply SUBSYSTEM_X

[...]

config SUBSYSTEM_X
	tristate

This is much cleaner, and way more flexible than "select". SUBSYSTEM_X
can still be configured out, and it can be set as a module when none of
the drivers are configured in or all of them are modular.

fa64e5f6a3 kconfig/symbol.c: handle choice_values that depend on 'm' symbols
If choices consist of choice_values of type tristate that depend on
symbols set to 'm', those choice_values are not set to 'n' if the
choice is changed from 'm' to 'y' (in which case only one active
choice_value is allowed). Those values are also written to the config
file causing modules to be built when they should not.

The following config can be used to reproduce and examine the problem;
with the frontend of your choice set "Choice 0" and "Choice 1" to 'm',
then set "Tristate Choice" to 'y' and save the configuration:

config modules
	boolean modules
	default y
	option modules

config dependency
	tristate "Dependency"
	default m

choice
	prompt "Tristate Choice"
	default choice0

config choice0
	tristate "Choice 0"

config choice1
	tristate "Choice 1"
	depends on dependency

endchoice

This patch sets tristate choice_values' visibility that depend on
symbols set to 'm' to 'n' if the corresponding choice is set to 'y'.

This makes them disappear from the choice list and will also cause the
choice_values' value set to 'n' in sym_calc_value() and as a result
they are written as "not set" to the resulting .config file.

5bcba792bb localmodconfig: Fix whitespace repeat count after "tristate"
Also recognize standalone "prompt".

Before this patch we incorrectly identified some symbols as not having a
prompt and potentially needing to be selected by something else.

Note that this patch could theoretically change the resulting .config,
causing it to have fewer symbols turned on. However, given the current set
of Kconfig files, this situation does not occur because the symbols newly
added to %prompts are absent from %selects.

6b87b70c53 unbreak allmodconfig KCONFIG_ALLCONFIG=...
Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used
to be equivalent to make allmodconfig; these days it hardwires MODULES to n.
In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is
treated as if it set it to n.

	Regression had been introduced by commit cfa98f ("kconfig: do not
override symbols already set"); what happens is that conf_read_simple()
does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and
has conf_set_all_new_symbols() skip modules_sym.

	It's pretty easy to fix - simply move that call of sym_calc_value()
into the callers, except for the ones in KCONFIG_ALLCONFIG handling.

5b61c7bd25 kconfig: fix qconf segfault by deleting heap objects
On Debian stable (qt-4.8.6) 'make xconfig' intermittently fails due to
qconf segfaulting at exit time in QXcbEventReader. The cause of this is
destructors on the heap objects never being called, so fix this by
properly deleting the heap objects before exit.

aab24a897c kconfig: return 'false' instead of 'no' in bool function
menu_is_visible() is a bool function and should use boolean return
values. "no" is a tristate value which happens to also have a value
of 0, but we should nevertheless use the right symbol for it.

This is a very minor cleanup with no semantic change.

The current (arbitrary) limit of 128 characters for path names has
proven too short for Android builds, as longer path names are used
there.

Change conf.c, so it can handle path lengths up to PATH_MAX characters.

588446a847 Use pkg-config to find Qt 4 and 5 instead of direct qmake
The Qt Project recommendation is that there should always be a "qmake"
binary and it should never be renamed. If it's necessary to handle
multiple Qt versions, the Qt Project recommends using qtchooser.

Unfortunately, some distros do not follow the recommendation, so we
would need to check qmake-qt4, qmake-qt5, etc. So, instead, let's try
pkg-config.

bd960f0983 scripts/kconfig/Makefile: Fix KBUILD_DEFCONFIG check when building with O=
My recent commit d2036f30cf ("scripts/kconfig/Makefile: Allow
KBUILD_DEFCONFIG to be a target"), contained a bug in that when it
checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to
the path.

This causes the build to fail when building out of tree (with O=), and
when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will
fail to find the 'defconfig' file, because we look in the build
directory not $(srctree), and so we will call Make again with
'defconfig' as the target. From there we loop infinitely calling 'make
defconfig' again and again.

The fix is simple, we need to look for the file under $(srctree).

ed94fea5ba kconfig/merge_config.sh: Support KCONFIG_CONFIG
All make targets support $KCONFIG_CONFIG because they
run scripts/kconf.  Make sure merge_config.sh accesses the
correct file in all cases.

Previously this script broke in two different code paths,
one for targets like kvmconfig (which use merge_config.sh -m
then call a target that respects KCONFIG_CONFIG) and one for
direct use of the script without -m, which called make rules
that edit KCONFIG_CONFIG but verified a different file.

The buildsystem will now only search for Qt 4 and Qt 5. Support for Qt 2
and 3 was dropped in the previous commits (Qt 3 was EOL'ed in 2010 or
so...).

For Qt 5, to be future-proof with the future direction notice appearing
in the 5.5 release, C++11 support is automatically enabled.
