Jakub Rzeszutko d4559f53fa lib: getopt: rework and extend getopt library
Getopt has been rework in this way that calling it does not require
extra state parameter and its execution is thread safe.
Global parameters describing the state of the getopt function have been
made available to ensure full API compatibility in using this library.
However, referencing these global variables directly is not thread
safe. In order to get the state of the getopt function for the thread
that is currently using it, call: getopt_state_get();

Extended the library with getopt_long and getopt_long_only functions.

Moved getopt libary from utils to posix.

menuconfig GETOPT
bool "Geopt library support"
help
This option adds support of getopt.
Different shell backends are use their own instance of getopt to
not interfere with each other.
All not shell threads share one global instance of getopt state, hence
apart from shell this library is not thread safe. User can add support
for other threads by extending function getopt_state_get in
getopt_common.c file.
This option enables the following function: getopt.
