X-Git-Tag: syslinux-4.05-pre1~20^2~30

hdt: Adding dump_mode & tftp_ip boot option

dump_mode=<dir> give the user a chance to select a directory on the tftp
server.

tftp_ip=<w.x.y.z> give the user a chance to select another tftp server
for dumping data. By default, we use the tftp that serves the pxe
booting.
