lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Remove redundant initialization. Don't use variable - just return the value.

Get rid of the msg_peek() function, which has a problem. If there was less data in the socket buffer than requested by the caller, the function would busy loop, as select(2) will always return immediately. We can just receive nvlhdr now, because some time ago we splitted receive of data from the receive of descriptors. MFC after: 1 week
