Makes tail -f for multiple files display the header only if another (ie. not
currently displayed) file changed.

md5sum b29ce23312e14eb15a143377d4a38473, was failing to unpack.
It so happened that this file has a run which exactly fills
the 90k buffer. The check was "size >= bufsize", apparently
it has to be ">".

While at it, move applet/config/kbuild bits into wall.c.
(This way, it's more visible that applet is suid'ed).

If our pkg-config queries pass back a flag like -pthread, the trylink
script will expand that to -l-pthread. So change trylink to only add
the -l prefix to a value that doesn't have a - prefix already.

Fron bug report:
If a CGI or proxied connection is rudely aborted (SIG_{KILL,BUS,SEGV})
then httpd will spin madly the poll loop in:
networking/httpd.c:1080
cgi_io_loop_and_exit()
Upon investigation I found that pfd[0].revents == 0x0018 (POLLHUP|POLLERR),
which leads to empty read, but the pfd[0].fd (STDIN_FILENO) is left open,
and in the FD list given to poll() which immediately returns to once
again inform the loop of (POLLHUP|POLLERR) condition of pfd[0].fd.
This continues until pfd[FROM_CGI].revents != 0

ar fields are fixed length text strings (padded with spaces). Ensure
bb_strtou doesn't read past the field in case the full width is used.
The fields are only read once, so the simplest/smallest solution to me
seems to be to just pass the length to read_num() and then zero terminate
the string before passing it to bb_strtou. This does mean that the fields
MUST be read in reverse order, so some minor reshuffling was needed.

iplink.c includes net/if_packet.h, which (on GLIBC)
only defines struct sockaddr_pkt. this struct is not
used anywhere in the code, and removing the #include
makes compilation succeed with musl libc.

This feature was removed in 72c99af
It is useful when process is removed from inittab and later added
back, but never terminated. It prevents init from spawning duplicate.

We store init actions forever. 256 bytes per action means that
a typical inittab of ~10 commands uses 2.5k just to remember
command strings - which are usually _much_ shorter than 256 bytes.
At a cost of a bit more code, it's possible to allocate
only actually needed amount.

devname is used by fscanf to store a string specified by '%20s'.
Extract from the man for the '%s' specifier:
Matches a sequence of non-white-space characters; the next pointer must be a
pointer to character array that is long enough to hold the input sequence and
the terminating null byte ('\0'), which is added automatically. The input
string stops at white space or at the maximum field width, whichever occurs
first.
Hence, the right length is 20 + 1 for the '\0'.
