259b3c047a sed: open input files sequentially to avoid EMFILE 
Currently, sed pre-opens all files, which may cause EMFILE errors

This needed some extensions correct_passwd() function,
which got renamed ask_and_check_password() to better describe what it does.

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-   '.

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.

46031da862 lineedit: initialize delptr 
In vi mode, the 'p' and 'P' commands caused a segfault when nothing had
been put in the buffer yet because the delptr was not initialized.

5368fe541c sha3: rename KeccakF->sha3_process_block76. 
This brings the naming more in line with other hashes.
Pulled most statics and constants into it.
Also noticed that two byte arrays are 1 element too big.
