compile netcfg on unix

fixed bug in netcfg created in last revision
netcfg gives error msg when driver is not loaded
zeroconfig now works with latest version of libini
also fixed use of static and link-local ip in zeroconfig
initial IPv4 variables are now 0.0.0.0 instead of 255.255.255.255
created kernel function that shows number of active network devices 
fixed the use of temp mac variable in IPV4.inc (variable is now in stack)
rewrite of ARP code, needs full testing/debugging (new application needed: ARP manager)
port numbers are now in INET byte order, as is in posix standards
