This updates the hal headers and ni libraries for image v19. There were
very few changes this time around, only some network communications stuff.
Also updated the minimum version number in the build properties to the new
image version

The build scripts were still calling the tail command for following the log
file, even though we're now using netconsole. I've removed them.
