beb57fb35d - Add function callback capability when variables are set.

  error code.

cc31700a92 - Add getoptsreset to be used as a callback function when OPTIND is set.
This is used to implement the POSIX behavior when OPTIND=1
- Call setvarsafe instead of setvar. If one ran
	"getopts optstr badvariable"
  where badvariable contained an illegal variable name, there was no way
  to recover, since setvar() would longjmp on the error.

0bc88b2434 getopts fixes:
1. OPTIND value was not computed correctly when the argument was part of the
   option string (i.e. for "l:" "-l 1" was working "-l1" was not). (PR/2505).
2. OPTARG was not being unset in case of errors [in the non POSIX error case].
3. optvar could be set to random values.
4. Option string starting with a : was not treated specially as POSIX
   specifies (if the option string starts with a :, then there is no
   error printed when there are missing option arguments or illegal options,
   and OPTARG and optvar are being set specially).
5. Implemented getopts "opts" optvar [arg]. The optional argument case
   was not implemented.

To do:
- what does Posix say about resetting the getopts state? Bash does it
  by setting OPTIND=0; is that correct? Should we be doing the same thing?
- should we be using getopt(3) for everything internal to the shell? Is that
  feasible because we might need to handle multiple invocations at once.

edc0ef345c Fix growstackblock() 'newlen' calculations:
(1) it needs to be ALIGNed for both halves of the 'if,' and
	(2) if you're going to claim that you now have ALIGN(newlen)
	    bytes left, you should have actually allocated
	    ALIGN(newlen), rather than just 'newlen' bytes.
