jnlib - this is a collection of utility function which are
too small to put into a library.
libjnlib-config.h should be be modified for each project
to make these functions fit into the software. Mainly these
are memory functions in case you need another allocator.

*
* @Description
* This is my replacement for getopt(). See the example for a typical usage.
* Global flags are:
* Bit 0 : Do not remove options form argv
* Bit 1 : Do not stop at last option but return other args
* with r_opt set to -1.
* Bit 2 : Assume options and real args are mixed.
* Bit 3 : Do not use -- to stop option processing.
* Bit 4 : Do not skip the first arg.
* Bit 5 : allow usage of long option with only one dash
* Bit 6 : ignore --version
* all other bits must be set to zero, this value is modified by the
* function, so assume this is write only.
* Local flags (for each option):
* Bit 2-0 : 0 = does not take an argument
* 1 = takes int argument
* 2 = takes string argument
* 3 = takes long argument
* 4 = takes ulong argument
* Bit 3 : argument is optional (r_type will the be set to 0)
* Bit 4 : allow 0x etc. prefixed values.
* Bit 7 : this is a command and not an option
* You stop the option processing by setting opts to NULL, the function will
* then return 0.
* @Return Value
* Returns the args.r_opt or 0 if ready
* r_opt may be -2/-7 to indicate an unknown option/command.
* @See Also
* ArgExpand
* @Notes
* You do not need to process the options 'h', '--help' or '--version'
* because this function includes standard help processing; but if you
* specify '-h', '--help' or '--version' you have to do it yourself.
* The option '--' stops argument processing; if bit 1 is set the function
* continues to return normal arguments.
* To process float args or unsigned args you must use a string args and do
* the conversion yourself.
* @Example
*
* ARGPARSE_OPTS opts[] = {
* { 'v', "verbose", 0 },
* { 'd', "debug", 0 },
* { 'o', "output", 2 },
* { 'c', "cross-ref", 2|8 },
* { 'm', "my-option", 1|8 },
* { 500, "have-no-short-option-for-this-long-option", 0 },
* {0} };
* ARGPARSE_ARGS pargs = { &argc, &argv, 0 }
*
* while( ArgParse( &pargs, &opts) ) {
* switch( pargs.r_opt ) {
* case 'v': opt.verbose++; break;
* case 'd': opt.debug++; break;
* case 'o': opt.outfile = pargs.r.ret_str; break;
* case 'c': opt.crf = pargs.r_type? pargs.r.ret_str:"a.crf"; break;
* case 'm': opt.myopt = pargs.r_type? pargs.r.ret_int : 1; break;
* case 500: opt.a_long_one++; break
* default : pargs.err = 1; break; -- force warning output --
* }
