[syslinux] tftp-hpa enhancement

[Mickey Malone]

hpa,

Attached is the patch file. I stuck with the current defaults (write to file) and added a -B switch (short for Batch mode).

If the -B switch is present, then so does the -c command or we will notify the user.

I also moved all the tftp client output to stderr to keep file integrity during verbosity, updated the spec, and updated the man page.

So basically, this works and is somewhat my use case: 

tftp -B -m binary 127.0.0.1 69 -c get intiramfs | gzip -dc | cpio -id
