Fixed memory leak on old style command substitution
...
such as sh -c 'echo `echo foo`' .
The memory allocated with ckmalloc() at
parser.c:1349:readtoken1() (search for "done:" label)
was never freed.
I changed this to use 'string stack' framework of Ash.
Note that a string on string stack is properly freed on
exception and end of command parsing, and no explicit free
or signal handlings required.
See TOUR for an overview, and memalloc.[ch] for details
of string stack.

Unfortunately (as I expected) the previous change broke:
...
sleep
cmd='set `type "sleep"`; eval echo \$$#'
which=`eval $cmd`
echo $which
because the region did not get recorded at all, and it was interpreted as
a single word. I modified the code to keep track when the result of a
backquote expansion has been recorded to avoid recording it twice. I still
feel that this is not the right fix... More to come.

assignment. E.g.
echo ${foo:=`echo 1 2 3 4`}
prints:
1 2 3 1 2 3 4
because when the arquments are not quoted, the backquote result
gets recorded twice. The fix right now is to comment out the
record_region() call in expbackq(). I hope that it does not break
anything else.
