nsenter: fix parsing of -t, -S and -G options
-t, -S and -G each take mandatory integer arguments. getopt32long()'s
option string syntax for this type of argument is 'c:+', however nsenter's
opt_str uses 'c+', which specifies two options 'c' and '+' which do not
take arguments. This means that giving a target PID causes nsenter to
exit and print the usage string:
# nsenter -t1 sh
nsenter: unrecognized option: 1
BusyBox v1.27.2 (2017-12-12 10:41:50 GMT) multi-call binary.

The long form options are also broken:
# nsenter --setuid=1000 --setgid=1000 sh
BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
...
`nsenter --target=<pid> sh` parses correctly and appears to work, but
<pid> is ignored and set to 0. This doesn't raise an error unless one
of the namespace arguments is also given:
# ./busybox_unstripped nsenter --target=42 sh
# exit
# ./busybox_unstripped nsenter -n --target=42 sh

nsenter: Rename --network option to --net
In nsenter from util-linux, the long version of the -n option is
--net=<path>. BusyBox's version expects --network=<path>, so scripts
and examples written for util-linux's version cause BusyBox's version
to exit with the usage message.
Confusingly, until commit

claimed that the long option was indeed called --net; after that commit

udhcpd: fix "not dying on SIGTERM"
Fixes:
commit
52a515d18724bbb34e3ccbbb0218efcc4eccc0a8
"udhcp: use poll() instead of select()"
Feb 16 2017
udhcp_sp_read() is meant to check whether signal pipe indeed has some data to read.
In the above commit, it was changed as follows:
- if (!FD_ISSET(signal_pipe.rd, rfds))
+ if (!pfds[0].revents)
return 0;
The problem is, the check was working for select() purely by accident.
Caught signal interrupts select()/poll() syscalls, they return with EINTR
(regardless of SA_RESTART flag in sigaction). _Then_ signal handler is invoked.
IOW: they can't see any changes to fd state caused by signal haldler
(in our case, signal handler makes signal pipe ready to be read).
For select(), it means that rfds[] bit array is unmodified, bit of signal
pipe's read fd is still set, and the above check "works": it thinks select()
says there is data to read.
This accident does not work for poll(): .revents stays clear, and we do not
try reading signal pipe as we should. In udhcpd, we fall through and block
in socket read. Further SIGTERM signals simply cause socket read to be
interrupted and then restarted (since SIGTERM handler has SA_RESTART=1).
Fixing this as follows: remove the check altogether. Set signal pipe read fd
to nonblocking mode. Always read it in udhcp_sp_read().
If read fails, assume it's EAGAIN and return 0 ("no signal seen").
udhcpd avoids reading signal pipe on every recvd packet by looping if EINTR
(using safe_poll()) - thus ensuring we have correct .revents for all fds -
and calling udhcp_sp_read() only if pfds[0].revents!=0.
udhcpc performs much fewer reads (typically it sleeps >99.999% of the time),
there is no need to optimize it: can call udhcp_sp_read() after each poll
unconditionally.
To robustify socket reads, unconditionally set pfds[1].revents=0
in udhcp_sp_fd_set() (which is before poll), and check it before reading
network socket in udhcpd.
TODO:
This might still fail: if pfds[1].revents=POLLIN, socket read may still block.
There are rare cases when select/poll indicates that data can be read,
but then actual read still blocks (one such case is UDP packets with
wrong checksum). General advise is, if you use a poll/select loop,
keep all your fds nonblocking.
Maybe we should also do that to our network sockets?

grep: skip grepping symlinks to directories
When grep is passed -r, recursive_action will treat any symlinks to
directories not in the root as normal files, since it lstat's them and
is therefore told they are not directories. However, file_action_grep
will still try to fopen and read from them to see whether they match,
which varies in behaviour across platforms. Linux will give EISDIR and
thus grep will not find any matching lines, but FreeBSD will give the
raw contents of the directory itself, which may match the given pattern.
Also, if grep is passed -c, it will even print a count for these
symlinks, even on Linux.
Since this recursive_action behaviour is required for the correct
functioning of other applets, such as tar, grep should handle this
special case and skip any such symlinks.

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.
