79c618c411 Refactor catv. Move visible() from stty to libbb. 
Fixes the following TODO:

  stty's visible() function and catv's guts are identical. Merge them into
  an appropriate libbb function.

Also makes catv behave exactly like coreutils' cat -v e.g. it'll print 'M-^I'
instead of 'M-   '.

f6205c6ab7 md5/sha512: fix strict aliasing warnings 
If the target can tolerate these issues, then gcc is smart enough
to generate the same code (x86_64 produces the same code).  If the
target can't, then it needs the memcpy anyways.

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.
