chris f10d13fdee Extend tftp_stat to return the size of the file, rather than -1.
It's not very efficient, as it has to read the whole file, and count the
block sizes.  However, this is the only way to work out the size using the
tftp protocol.

This is needed to support loading modules from a tftp server with pxeboot.
