PR/43469: Antii Kantee: test/util/sh/t_expand:strip fails.
Bring back fixes from revision 1.75:

- Fix a couple of bugs to make the following two echo statements print the
  same output as they should:

    line='#define bindir "/usr/bin" /* comment */'
    echo "${line%%/\**}"
    echo ${line%%/\**}

1. ISDBLQUOTE() was not working properly for non VSNORMAL expansions because
   varnest was incremented before the variable was completely parsed. Add
   an insub adjustment to keep track of that.
2. When we have a quoted backslash, we either need to escape twice, because
   one level of escaping will be stripped later (in the variable substitution
   case) or simply enter the backslash.

the syntax maps to determine the beginning and end quotes (kill

the current syntax map. Keep a bitmap of doublequote state one bit

we don't need any additional memory, but for more we allocate
dynamically.

Fix switch alias handling. Inspired from FreeBSD, but corrected to handle
alias expansion inside the switch as appropriate. This is achieved by a
flag noalias which is turned on and off in as we parse. In the following
example [1] and [0] indicate the value of noalias.

[0] case <expr> in
[1] <lit> ) [0] <expr> ;;
[1] <lit> ) [0] <expr> ;;
...
[1] esac [0]

FreeBSD does:

[0] case <expr> in [1]
<lit> ) <expr> ;;
<lit> )  <expr> ;;
...
esac [0]

This handles the following shell script:

alias a=ls

case $1 in
a)	echo a;
	a;;
f)	echo f;;
*)	echo default;;
esac

un-__P functions declared in parser.h.  host programs include parser.h,
and so it shouldn't use __P.  (this should probably be done better, by
not declaring the parser functions in headers used by host programs,
but this works well enough.)

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.
