/* Simple minded read-ahead/write-behind subroutines for tftp user and
server. Written originally with multiple buffers in mind, but current
implementation has two buffer logic wired in.
Todo: add some sort of final error check so when the write-buffer
is finally flushed, the caller can detect if the disk filled up
(or had an i/o error) and return a nak to the other side.

================
tftpd is not a full tftp server, multiple buffers need to be implemented so
that it can transfer big size files, for example to serve PXE file pxelinux.0.
