This is a busybox port of the Minix shell. It is reasonably capable,

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.

> 1) remove many memory leaks
> 2) add support read_only protect (require write builtin function for set this,
> I write this special for variable HUSH_VERION=0.01)

> free(arg).
> 6) next add integraion with libbb
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.

This patch covers one big part of variable handling.
...
$ a=b foo
should be handled correctly.
$ a=b
is parsed OK, but the actual variable setting is not
yet written. Except for some weird exceptions related
to quoting rules, this code passes (matches ash behavior)
all the tests I threw at it.
If someone now writes set_local_var(), and updates lookup_param()
to match, we can claim success!

This checkin also removes sh.c. In the future sh.c will be a symlink to
your shell of choice. For now, this symlink will default to pointing to
lash.c (as in the past). If you change the symlink to point to hush.c,
then thats what you will get. This symlink business is a temporary situation,
which will be cleaned up Real Soon Now(tm).
