4928e9f7d0 losetup: assorted fixes. Closes 6314
"losetup -d" was not complaining that LOOPDEV is missing.
"losetup -a" was listing only up to /dev/loop9.
"losetup -f" looped forever if llop0 was taken, and never tried
anything after /dev/loop9.
"-o" with other options (say, -r) had no effect.

879f008a8f 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.

[1] A MIPS-based board with glibc 2.9, Linux 2.6.32.27.

b6dc13c2d3 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.

5fc0585c01 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.

Add an exception to the setting of REG_NOSUB for OPT_x and add some test
cases to test the behaviour of -x.

c3cf1e30a3 mdev: use $DEVNAME in uevent sysfs file for device node name
516530c932 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.
