was written by Aaron Lehmann <aaronl@vitelus.com> for busybox. This
patch makes a few trivial changes to Aaron's code so that it can be
used (in theory) by the other shells as well...

1) ping cleanup (compile fix from this patch already applied).
2) traceroute call not spare ntohl() now (and reduce size);
3) Fix for functions not declared static in insmod, ash, vi and mount.
4) a more simple API cmdedit :))
5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)

to know which shell is in use. Add in 'help' to list available
builtins, and fixup msh so it can do STANDALONE_SHELL.

totally breaking the shell. Simple thinge like 'FOO=100' caused
it to segfault. It turns out that disabling "bltincmd" is a very
bad idea.

changes, esp describing all the current ash configuration options.
Now ash adds 66k in the default configuration.

handles all the basic stuff (for, case/esac, while, if/then/else), and
is very small (adds just 38k on x86). It is not as rigorously correct
about Bourne semantics as bash, but for most things it is quite
workable. There is still some work to be done to further shrink it (it
has its own globbing functions instead of using the libc ones, for
example), but it is quite usable as is.

commented out instead of simply deleted (so they could be re-enabled)
and the builtins all work. This adds 72k.

Fixes the interaction between if/then/else/fi syntax and variables.
I planned to do it right from the beginning, but my implementation
was buggy. Also adds the relevant test cases. Also adds some old
Matt Kraai variable test cases that got left out somehow.

Valdimir's patch missed two cases of local variable handling
FOO=bar
export FOO=baz
unset FOO
and
export FOO=bar
FOO=baz
which were working before, so I fixed those two cases.

signal handling in cmdedit.c. Disabling it makes the shells behave
themselves again. hush isn't quite there, but is getting close...
