SDD 01923ecb69 dwt/tcpip: map the socket API and fetch a file over TFTP into RAM ...

The firmware's tftp_open hangs in its resolver from the rdebug process, so
the payload speaks RFC 783 over the firmware socket API: socket(2,2,0),
sendto(RRQ), recvfrom(DATA)/ACK into a malloc'd buffer, close. Verified
live: 600 B fetched from 192.168.99.1 into the malloc buffer, server RRQ
logged, and rdebug peek matches probe.bin byte-for-byte.

Notes: dwt/notes/TCPIP.md (function table, ABI, limits) and the
loader/transport hand-off in dwt/notes/LOADER_CROSS.md.
