Update preloaded module prim_inet needed!
Support for 2 bytes and 4 bytes big, little and native endian header by gen_tcp sockets, 'spawn',
ports and also by erlang:decode_packet/3.

To select endianess of port other than big, you have to add one of three options:
    {packet_endian, big} (it is default),
    {packet_endian, little},
    {packet_endian, native}.

Native endian implemented by memcpy, thus middle endian also supported.
In win32 native endian implemented as little endian, because win32 supports only
little endian machines.

Fixed TCP sockets on big endian machine with {packet_endian, native} mode
