++ New features:
2007-05-23 Frédéric Bernon
* api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
code in only one part...
2007-05-18 Simon Goldschmidt
* opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
elements to overflow. This is achieved by adding some bytes before and after
