It's deprecated since 2009 and interferes with make_single_applets.sh tests.

stop lying about [[ test support
probably because it was not properly ifdefed around, and was enabled
even when bash compat is off.
I just tested it - it works:
$ [ *.diff = z.diff ]; echo $?
0
$ [[ *.diff = z.diff ]]; echo $?
1
Of course, not all numerous bash tricks of [[ ]] are implemented...

Splitting these options makes it self-documenting about what
bash-compatible features we have.

This makes hash and ash more symmetrical wrt config menu and config
options.

Redundant help texts (one which only repeats the description)
are deleted.
Descriptions and help texts are trimmed.
Some config options are moved, even across menus.
No config option _names_ are changed.

It's a bit overkill (who would want it off?) but ash already has it
configurable. Let's be symmetric.
Also tweak kbuild logic to use ASH_BUILTIN_ECHO to select echo.o,
not ASH.

The same can be done for msh, but we are probably better off just deleting it
in a next versio or two.

Indirect calls are more difficult to predict.
Unfortunately, on x64 direct call is 5 bytes while indirect "call (reg+ofs)"

Was playing with "sleep 3 | exit 3 & wait %1" and noticed that often
SIGCHLD arrives even before I get to signal masking. Can avoid it in this
case.

It would be nice to provide bash-like "remember las exitcode"
thingy, but it's a bit complex. For now, match ash and dash.

Resetting to 0 should happen in "esac". Matched branch must
still see previous $?.
