christos a00e49c200 Getopts bugs again (I'll never get this right).
- make sure that OPTIND is set correctly even in the absence of options.
- don't keep stale state between getopts calls.

christos 9530a32719 Fix bug in getopts code where the argument list got truncated.
From Todd Miller.

christos ccce082dd2 Fix miscellaneous getopts problems:
- the 3 argument version of getopts would not reset properly
- OPTARG did not get cleared after a non argument option was found
- OPTIND was not set properly after a non argument option.

christos fd8c99438e PR/2808: POSIX 1003.2: first arg after -c cmd is $0, remainder $1...
(from FreeBSD)

christos 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.

christos 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.

bug.

christos 6ee2193d9a Reverted to set - turning off -x and -v. Charles corrected me... It is part
of POSIX.

christos ad1f891148 set -
does not anymore clear the -x and -v flags. This was incompatible with
all other bourne shell implementations.
