Title: RESETTING GETOPT()
Description: There is an issue with the way that getopt() handles errors that
return '?'.
1. Does getopt() reset its global variables after returning '?' so
that it can be re-used? That would be required to support where
the caller terminates parsing before reaching the last parameter.
2. Or is the client expected to continue parsing after getopt()
returns '?' and parse until the final parameter?
The current getopt() implementation only supports #2.

Update: A new dtoa version is not available and enabled with
CONFIG_NANO_PRINF. However, the old version of dtoa is still in
in place and lib_libvsprintf() has been dupliated. I think this
issue should remain open until the implementations have been
unified.
