udp_io, traceroute: Standardise IPv6 PKTINFO handling to be portable
The current standard (RFC 3542) is for IPV6_RECVPKTINFO to be given to
setsockopt, and IPV6_PKTINFO to be used as the packet type. Previously,
RFC 2292 required IPV6_PKTINFO to be used for both, but RFC 3542
re-purposed IPV6_PKTINFO when given to setsockopt. The special
Linux-specific IPV6_2292PKTINFO has the same semantics as IPV6_PKTINFO
in RFC 2292, but was introduced at the same time as IPV6_RECVPKTINFO.
Therefore, if we have IPV6_RECVPKTINFO available, we can use the RFC
3542 style, and if not, we assume that only the RFC 2292 API is
available, using IPV6_PKTINFO for both.

df: Use statvfs instead of non-standard statfs
Platforms differ on what their implementations of statfs include.
Importantly, FreeBSD's does not include a f_frsize member inside struct
statfs. However, statvfs is specified by POSIX and includes everything
we need, so we can just use that instead.

lineedit: improve multiline PS1 - redraw using last PS1 line. Closes 10381
This patch only affects prompts with newlines.
We redraw the prompt [+ input] occasionally, e.g. during tab completion,
history browsing or search, etc, and we expect it to align with prior
redraws, such that the visible effect is that only the input changes.
With multi-line PS1, redraw always printed the prompt some lines below
the old one, which resulted in terminal scroll during every redraw.
Now we only redraw the last PS1 line, so vertical alignment is easier to
manage (we already calculated it using only the last line, but re-drew
all lines - that was the culprit), which fixes those extra scrolls.
Notes:
- We now use the full prompt for the initial draw, after clear-screen (^L),
and after tab-completion choices are displayed. Everything else now
redraws using the last/sole prompt line.
- During terminal resize we now only redraw the last[/sole] prompt line,
which is arguably better because it's hard to do right (and we never did).
- Good side effect for reverse-i-search: its prompt now replaces only the
last line of the original prompt - like other shells do.

This is particularly convenient when debugging in gdb interactively,

i2c-tools: don't include linux/i2c-dev.h
Installing headers from upstream i2c-tools makes it impossible to
build the busybox version due to redefined symbols. This is caused by
the fact that linux/i2c-dev.h from i2c-tools overwrites the one from
linux uapi and defines symbols already defined by linux' linux/i2c.h.
Drop this include and simply re-implement the relevant defines from
linux/i2c-dev.h in miscutils/i2c-tools.c.
Tested by building on systems with and without i2c-tools headers.

kill: add '--' option to separate options from arguments
Using a negative pid to send TERM to a process group results in an
obscure error:
$ ./busybox kill -12345
kill: bad signal name '12345'
This is intended. Manpage says:
ARGUMENTS
pid Each pid can be one of four things:
...
-n where n is larger than 1. All processes in process group
n are signaled. When an argument of the form '-n' is
given, and it is meant to denote a process group, either
a signal must be specified first, or the argument must be
preceded by a '--' option, otherwise it will be taken as
the signal to send.
However, we did not support "--". Add this capability to BusyBox.
