Gregory Nutt af3c76bb53 Correct some getopt() logic 
1. Null pointer dereference:

-  for (ndx = 0; longopts[ndx].name[0] != '\0'; ndx++)
+  for (ndx = 0; longopts[ndx].name != NULL; ndx++)

2. Handle single character long options.  An option like -x could be either a short option or a long option (under getopt_long_only()).  This case was not being handled correctly.

3. Add missing support for optional arguments to short options (indicated with two "::"

This effects all members of the getopt() family of APIs.

Tested on the simulator using extensions to apps/testing/ostest.
