This commit adds an as-of-yet untested implemented of UDP write buffering. Squashed commit of the following: net/udp: Address most of the issues with UDP write buffering. There is a remaining issue with handling one network going down in a multi-network environment. None of this has been test but it is certainly ready for test. Hence, the feature is marked EXPERIMENTAL. net/udp: Some baby steps toward a corrected write buffering design. net/udp: Remove pesky write buffer macros. Eliminate trailing space at the end of lines. net/udp: A little more UDP write buffering logic. Still at least on big gaping hole in the design. net/udp: Undefined CONFIG_NET_SENDTO_TIMEOUT. net/udp: Crude, naive port of the TCP write buffering logic into UDP. This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering. net/udp: Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.
