i2cdump: don't use common_bufsiz1
Commit
e6a2f4cc changed the way common_bufsiz1 works. Now it needs to
be initialized before using, but i2cdump wasn't updated by said patch.
Since the fact that we're using common_bufsiz1 here isn't obvious (no
G_INIT() macro, no other global variables), drop it and simply
allocate the integer array required for block reads on the stack.

ping: populate icmp_id field for "simple" ping too
The ICMP RFC says that identifier and sequence number may be zero.
Having them zero for a Echo message, along with a data of zero's
as well will result in a Echo reply message with only zero's.
Some NAT implementations seem to get the checksum wrong on these
packages. Setting a checksum of 0x0 instead of 0xffff.
Through NAT:
Internet Control Message Protocol
Type: 0 (Echo (ping) reply)
Code: 0
Checksum: 0x0000 [incorrect, should be 0xffff]
Identifier (BE): 0 (0x0000)
Identifier (LE): 0 (0x0000)
Sequence number (BE): 0 (0x0000)
Sequence number (LE): 0 (0x0000)
Data (56 bytes)
Data:
000000000000000000000000000000000000000000000000...
[Length: 56]
Without NAT:
Internet Control Message Protocol
Type: 0 (Echo (ping) reply)
Code: 0
Checksum: 0xffff [correct]
Identifier (BE): 0 (0x0000)
Identifier (LE): 0 (0x0000)
Sequence number (BE): 0 (0x0000)

[Length: 56]
And this in turn will make some hardware MAC checksum offloading
engines drop the packet.
(This was seen with a Synopsis MAC, the same one used in for instance the
stmmac Ethernet driver in the linux kernel.)
This change can be seen as a workaround for bugs in other layers.
But just setting an identifier for the Echo message packet will
avoid prodding the hornets nest.

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

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: 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
