20cd31a2d7 lineedit: don't block when looking for escape sequence in vi-mode 
In vi-mode lineedit tries to detect some escape sequences.
After the ESC it reads the next character to check for certain
values.  This read should have a timeout or a user-entered ESC to
switch to command mode doesn't properly handle the next character.

8d75d794ea libbb: use sendfile() to copy data between file descriptors 
Busybox already uses sendfile in httpd. This patch proposes to use it
globally to copy data between file descriptors.

It speeds up the copying on slow systems a lot - below are the times needed
to copy a 450Mb file with and without this option enabled on a BeagleBone
Black:

sendfile:
user    0m0.000s
sys     0m8.170s

read/write 4k:
user    0m0.470s
sys     0m16.300s

04c1417602 libbb: use ARG_MAX for bb_arg_max() only if it's 60k+ 
Sometimes ARG_MAX is small (like 32k) yet sysconf(_SC_ARG_MAX)
is big, and people prefer using the bigger value.

OTOH, with sufficiently large ARG_MAX, further wins from
sysconf(_SC_ARG_MAX) being bigger are exponentially smaller:
you can see 4 times fewer fork+execs when you run find, but
when each execed process already takes a thousand parameters
it's likely execution time is dominated by what that process
does with each parameter.

Thus, with this change ARG_MAX is used if it's sufficiently big,
otherwise sysconf(_SC_ARG_MAX) is used.

/search_for_nonexistent_string: both will read to EOF now

f92f1d0181 find: use sysconf(_SC_ARG_MAX) to determine the command-line size limit 
The find utility uses a hardcoded value of 32 * 1024 as the limit of
the command-line length when calling 'find -exec ... {} +'. This results
in over 4 times more execve() calls than in coreutils' find.

This patch uses the limit defined in system headers.

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
