commit a2b50809c766bfb1f94ac0fc7c76517e3e3a66ab
Author: Max <msuraev(a)sysmocom.de>

cosmetic: relax UDP length check
Previously recv() returning 0 for UDP socket was considered as error
although it's legitimate return value for empty UDP packets. Relax the
error check to avoid confusing error messages.
The function behavior is the same:
* msg is not altered while receiving 0-length UDP packet
* return value is 0
The only result of the relaxed error check is the absense of error log
message for 0-length UDP packet.

examples: add simple UDP client/server
In addition to showing basic UDP send/receive example, it helps to test
corner-case when dealing with 0-length UDP packets.
