This functionality is is enabled by setting CONFIG_SHELL_GETOPT.
It is not active by default.
User can call following functions inside command handlers:
- shell_getopt - getopt function based on freebsd implementation
- shell_getopt_status_get - returns getopt status
Beware when getopt functionality is enabled shell will not parse
command handler to look for "-h" or "--help" options and print
help message automatically.
