kconfig/lxdialog: rationalise the include paths where to find {.n}curses{,w}.h
The current code does this:
if [ -f /usr/include/ncursesw/curses.h ]; then
echo '-I/usr/include/ncursesw -DCURSES_LOC="<ncursesw/curses.h>"'
elif [ -f /usr/include/ncurses/ncurses.h ]; then
echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses.h>"'
elif [ -f /usr/include/ncurses/curses.h ]; then
echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses/curses.h>"'
[...]
This is merely inconsistent:
- adding the full path to the directory in the -I directive,
- especially since that path is already a sub-path of the system
include path,
- and then repeating the sub-path in the #include directive.
Rationalise each include directive:
- only use the filename in the #include directive,
- keep the -I directives: they are always searched for before the
system include path; this ensures the correct header is used.
Using the -I directives and the filename-only in #include is more in
line with how pkg-config behaves, eg.:
$ pkg-config --cflags ncursesw
-I/usr/include/ncursesw
This paves the way for using pkg-config for CFLAGS, too, now we use it
to find the libraries.

menuconfig: optionally use pkg-config to detect ncurses libs
When building ncurses with --with-termlib several symbols get moved from
libncurses.so to libtinfo.so. Thus when linking with libncurses.so, one
additionally needs to link with libtinfo.so.
The ncurses pkg-config module will be used to detect the necessary libs for
linking. If not available the old heuristic for detection of the ncurses libs
will be used.

menuconfig: fix extended colors ncurses support
The ncurses library allows for extended colors. The support for extended
colors support depends on wide-character support. ncurses headers
enable extended colors (NCURSES_EXT_COLORS) only when wide-character
support is enabled (NCURSES_WIDECHAR).
The "make menuconfig" uses wide-character ncursesw library, which can be
compiled with wide-character support, but does not define NCURSES_WIDECHAR
and it's using headers without wide-character (and extended colors) support.
This fixes problems with colors on systems with enabled extended colors
(like PLD Linux). Without this patch "make menuconfig" is hard to use.

kbuild: Fix gcc -x syntax
The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.
This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.
Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow
ncursesw to be used as a replacement ncurses. However, when checking what
header file to include, we do not check /usr/include/ncursesw directory.
Add /usr/include/ncursesw to the list of directories that are checked.

applet_tables: save space by removing applet name offsets
The array applet_nameofs consumes two bytes per applet. It encodes
nofork/noexec flags
suid flags
the offset of the applet name in the applet_name string
Change the applet_table build tool to store the flags in two separate
arrays (applet_flags and applet_suid). Replace applet_nameofs[] with a
smaller version that only stores a limited number of offsets.
This requires changes to the macros APPLET_IS_NOFORK, APPLET_IS_NOEXEC
and APPLET_SUID.
According to Valgrind the original find_applet_by_name required
353 cycles per call, averaged over all names. Adjusting the number
of known offsets allows space to be traded off against execution time:
KNOWN_OFFSETS cycles bytes (wrt KNOWN_OFFSETS = 0)
0 9057 -
2 4604 32
4 2407 75
8 1342 98
16 908 130
32 884 194
This patch uses KNOWN_OFFSETS = 8.
v2:
Remove some dead code from the applet_table tool;
Treat the applet in the middle of the table as a special case.
v3:
Use the middle applet to adjust the start of the linear search as
well as the last applet found.
v4:
Use an augmented linear search in find_applet_by_name.
Drop the special treatment of the middle name from get_applet_name:
most of the advantage now derives from the last stored value.

ifupdown: allow duplicate interface definitions
This patch allow to have multiple interface definitions, much like
Debian's ifupdown. More specifically, it removes the check for a
duplicate definition, so the impact on binary size should be fairly
minimal.
This configuration:
iface eth0 inet static
address 192.168.0.15
netmask 255.255.0.0
gateway 192.168.0.1
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
Will add two addresses to eth0 if ip is used. If ifconfig is used,
the standards methods will likely not stack, but the administrator may
still use the manual method. The DHCP method may work depending on the
DHCP client in use.
This is a fairly advanced feature for power users who knows what they
are doing. There are not many other network configuration systems that
allows multiple addresses on an interface.

taskset: fix non-fancy cpuset printing on big-endian
The non-fancy version of the from_cpuset uses CPU_SETSIZE as if it
represents the number of bytes in the cpuset, while it is actually
the number of bits. This leads to out-of-bounds accesses on the
cpu_set_t in the big-endian case. Basically all uses of CPU_SETSIZE
have to be divided by 8. This is done correctly in the fancy version
of from_cpuset.
In addition, the big-endian case is completely wrong to begin with.
All standard C libraries that I know of implement cpu_set_t as an
unsigned long array, so both for big and little endian, the least
significant bits are in the beginning of the array. Therefore, the
approach taken for the little endian case is equally valid. We only
need special handling for big endian when CPU_SETSIZE is large and
we use an unsigned long long to get more bits out.

Fix compiling with musl's utmp stubs
This patch fixes compiling busybox with FEATURE_UTMP and _WTMP enabled.
musl, while not really support utmp/wtmp, provides stub functions, as well
as variables such as _PATH_UTMP, so that programs using utmp or wtmp can
still compile fine.
My reasoning for this patch is that on Exherbo, I'm currently trying to get
us to be able to use the same busybox config file for both glibc and musl
systems, using utmp/wtmp on systems that support it, and using the stubs
on musl without needing two different configs.
As of latest musl git, it provides all utmp functions needed; 1.1.12 doesn't,
but I sent a patch to Rich to add the utmp{,x}name functions expected to
exist, which was merged into musl upstream.
