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.

This library is going to be used by the shell module. Some shell users
are not satisfied with subcommands alone and need to use the options
for commands as well.

We expect to have more libraries with incopatible license. There must
be a common place for such software. It seems that lib/util is good
place for that.
