Closes PR #6794 .
I thought Christos committed this but not appeared yet. :)
The setstackmark()/popstackmark() pair in dotcmd(), used for freeing
stack storage possibly allocated by find_dot_file(), is redundant for now
since dotcmd() is surrounded by another pair in evalcommand().
This redundancy, however, may help future modifications
(suggested by Christos).

PR/6213: Urban Boquist: /bin/sh does not handle a trapped signal correctly
...
The problem was that system calls got restarted after a signal,
instead of returning EINTR. Thus the read builtin, had no way to
know that a signal occured that could change the course of execution.
Since the code has sprinkled checks for EINTR all over the place,
it is supposed to work properly with non restartable syscalls.
The fix is to use siginterrupt(signo, 1), before setting a signal
handler, to make sure that system calls don't get restarted.

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.
