Subject: libnet: Make netapps.h includable from .code files

Unfortunately netapps.h currently can't be included from .code
Forth-to-C wrapper files - it includes tftp.h which in turn
includes ipv6.h, and that header contains some constructs which
can't be used in .code files. So let's make netapps.h independent
from tftp.h and add some "extern" keywords like it is done with
the other header files already that are included from .code files.
