iplink: comment out include <net/if_packet.h>

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.

It is useful when process is removed from inittab and later added
back, but never terminated. It prevents init from spawning duplicate.

init: don't use fixed size buffer for command

We store init actions forever. 256 bytes per action means that

networking: fix potential overflow in ife_print6()

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'.

lsof: correct check for symbolic link

Busybox lsof used the d_type field of a 'struct dirent' to verify whether the
entry is a symbolic link. This field, however, is not portable. On at least
one board [1] I have seen, that field is 0, and the check fails even though
the entry is a link.

The explicit check for a symbolic link is really only needed to skip the
default directory entries '.' and '..'. The directory /proc/<pid>/fd/
should not contain anything else but these two and symbolic links.
With these assumptions, this patch replaces the explicit link check with a
basic check for '.' and '..' (and any hidden file). In the unlikely case that
there are other file types, xmalloc_readlink() will return NULL, and we can
skip the entry.

sulogin: allow system maintenance login if root password is empty

The current password checking is unable to distinguish between the user
entering an empty password or pressing Control-D. As a result, an empty
password always results in normal startup.

We modify bb_ask to return NULL if Control-D is pressed without entering
a password. The sulogin applet is then modified to only proceed to
normal startup if bb_ask returns NULL. This covers EOF with no password,
interrupt by timeout and ^C.

grep: fix grep -x to not set REG_NOSUB

When -F isn't specified (and !ENABLE_EXTRA_COMPAT), grep -x uses
regexec's regmatch_t output to determine if the match was the entire
line. However it also set the REG_NOSUB flag which makes it ignore the
regmatch_t argument.

cases to test the behaviour of -x.

mdev: use $DEVNAME in uevent sysfs file for device node name

516530c932bd17d87c9eb4347a490be051e495f4 uses $DEVNAME variable
for device node name. This is fine, but only works for hotplugging,
"mdev -s" will behave differently when DEVNAME and basename(path)
differ.

This patch extracts the DEVNAME from the uevent sysfs file in
make_device(), thus works for hot- and coldplugging; so using
the environment DEVNAME on hotplug events is no longer necessary.
