General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47Z

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.

Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

libc/db/hash: cap auto-tuned block size with a value that actually works

2010-04-05T10:12:21Z

This fix mostly matters after r206129 that made it possible for st_blksize to be greater than 4K. For this reason, this change should be MFC-ed before r206129. Also, it seems that all FreeBSD uitlities that use db(3) hash databases and create new databases in files, specify their own block size value and thus do not depend on block size autotuning.

Fix typo: compatability -> compatibility.

Compatability is not an existing english word. Add $FreeBSD$.
