sys: further adoption of SPDX licensing ID tags.

2017-11-20T19:43:44Z

Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Rationalize BSD license on sys/*/include/float.h

Remove the advertising clause from the Regents of the University of California's license, per the letter dated July 22, 1999. Update clause numbering.

Add C11 macros describing subnormal numbers to float.h.

gcc is using. This fixes devstat consumers (like vmstat, iostat, systat) so they don't print crazy zillion digit numbers for disk transfers and bandwidth. According to gcc, long doubles are 64-bits, rather than 128 bits like the SVR4 ABI spec wants them to be.. Note that MacOSX also treats long doubles as 64-bits, and not 128 bits, so we are in good company. Reviewed by: das Approved by: grehan
