I have reworked tftp support: now barebox tftp implementation is used on top
of picotcp udp/ip stack and works 2 times slower than original u-boot stack-based
implementation (I have tested it with sandbox arch).

Please see draft tftp commit here: https://github.com/frantony/barebox/tree/20150620.picotcp

I'll try to switch barebox nfs support to picotcp udp/ip in several days.
