TFTP write() in 4.5.0 [PATCH]

[Vyacheslav V. Burdjanadze]

This patch enables tftp write operation (at least) for rtems-4.5.0 
release. This is actually slighty modifyed v1.20 if tftpDriver.c under
libnetworking/lib. I did it because I need it in my work that is based
on 4.5.0 release and I have not time to wait for next release. May be
someone got the same problems. So:

1. Get libnetworking/lib/tftpDriver.c v1.20
2. Apply following patch
