functions for converting between host and network byte order. These
names are the de facto standard names for this functionality because
of the original BSD TCP/IP implementation. But they cause problems for
uIP/Contiki: some platforms define these names themselves (Mac OS,
most notably), causing compilation problems for Contiki on those
platforms.
This commit changes all htons to uip_htons instead. Same goes for
htonl, ntohs, and ntohl. All-caps versions as well.
allows a program to register an 8-bit service ID that gets
disseminated to the entire network, as long as a servreg-hack daemon
is running on all neighbors. Other nodes can look up the service ID to
figure out what nodes in the network offer this service.
This is officially labeled as a "hack" so that we don't get too comfy
with it; this hack is not the future of service discovery and
advertisement in Contiki.
