Merge with BusyBox 1.24.0.
...
There's really only one bug fix in here that should be significant for GNO hush. The other changes should be inconsequential, AFAIK.

Fix problem where the system crashed as soon as you typed anything at the hush prompt in TMTerm or GSI.
...
The problem seemed to be that it crashes if the t_intrc special character is set to -1 on a pty. I worked around this by setting it to an obscure control character instead in that case.

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.

Add support for moving forward/backward one word with OA-left/right on GNO and Ctrl/Alt/Command-left/right on VT100-style terminals.
...
The support for OA-left/right on GNO uses the OA2META ioctl option to map OA-x to ESC x.
VT100-type terminal emulators have significant variations in what modifier combinations they'll pass through and what escape sequences they produce. Hopefully at least one of them works on just about everything.

Fix lineedit to process down arrow key properly.
...
This was broken by the change to using CRMOD mode, which actually does mapping on input as well as output. The fix is to set the terminal to "vt100 arrow" mode, which is an undocumented option that translates arrows to vt100-style escape sequences (also used by gsh).
(Note that the earlier patch actually makes us use CRMOD mode most of the time, not non-CRMOD mode as the summary erroneously says.)

Change lineedit so the terminal isn't kept in CRMOD mode most of the time.
...
This is important because CRMOD mode prevents text from backgrounded programs from being printed properly. It also leaves the terminal in an inappropriate state if hush crashes or is killed.
For the time being, we still switch briefly to CRMOD mode when we want to print just a CR.

Disable functionality for printing the time in the shell's prompt. This required strftime(), which is missing in GNO 2.0.6.

It would have been possible to add a version of strftime(), but it didn't seem worth it for this little bit of functionality. It should also be possible to get similar functionality by invoking an external program like "date" in PS1.

lineedit: histfile can get emptied when CONFIG_FEATURE_EDITING_SAVE_ON_EXIT=y
...
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:

$ ./busybox ash
