Changes in v2: none.

Changes in v3:
 - rebased on top of the net/tftp.c cleanup;
 - made do_tftpsrv() static;
 - improved tftpsrv command help;
 - removed all #ifdefs that used to remove negligible amounts of compiled code,
   at the cost of a much less readable source file; after measurements, it
   turned out this change does not increase code size.
