In standalone shell mode search the applet table as well as PATH
when tab completing a command.
Use a stupid linear search: we're also about to read all the
directories on PATH so efficiency isn't a big concern.

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.

When CONFIG_FEATURE_EDITING_SAVE_ON_EXIT is set to y, the histfile
will get cleared if the total amount of history lines is less than MAX_HISTORY.
Only if the histfile is not empty _and_ the amount of lines currently
in memory are equal to or greater than MAX_HISTORY, history saving will
work as expected with this feature enabled.
Output from defconfig + CONFIG_FEATURE_EDITING_SAVE_ON_EXIT=y:
$ echo "foo" > ~/.ash_history
$ ./busybox ash
~/busybox/a $ echo "bar" > /dev/null
~/busybox/a $ exit
$ cat ~/.ash_history
$
Output with the patch applied and same config as above:
$ echo "foo" > ~/.ash_history
$ ./busybox ash
~/busybox/b $ echo "bar" > /dev/null
~/busybox/b $ exit
$ cat ~/.ash_history
foo
echo "bar" > /dev/null
exit

First change fixes "read -n NUM". Apparently poll() won't report
data availability if cc[VMIN] > 1 until there are at least cc[VMIN] bytes.

Using ash in busybox git version dea28e1e, tab completion doesn't seem
to work properly for filenames that have special characters (such as
spaces) in them. For example, with filenames "foo bar" and "foo zap",
typing "ls fo<TAB>" correctly expands to "ls foo\ ", but then
continuing to type "b<TAB>" will produce "ls foo\ bbar", which is not
correct (the 'b' is duplicated).

pos_buf is a strange hack, easy to do without it.
This also allows lines >32k long to be handled.

Decoupled variables reused for unrelated purposes: apparently,
