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

hash(3): protect in-memory page when using cross-endianness.

2016-09-26T16:06:50Z

When writing out pages in the "other endian" format, make a copy instead of trashing the in-memory one. Obtained from: NetBSD (CVS rev. 1.29)

Fix prototype of dbm_open().

2016-05-31T18:32:57Z

The last argument of dbm_open() should be a mode_t according to POSIX; not an int. Reviewed by: pfg, kib Differential Revision: https://reviews.freebsd.org/D6650

libc: make more use of the howmany() macro when available.

2016-04-26T01:17:05Z

We have a howmany() macro in the header that is convenient to re-use as it makes things easier to read.

libc: use our roundup2/rounddown2() macros when param.h is available.

2016-04-20T01:21:39Z

rounddown2 tends to produce longer lines than the original code but still it makes the code more readable.

libc: replace 0 with NULL for pointers.

2016-04-10T19:33:58Z

While here also cleanup some surrounding code; particularly drop some malloc() casts. Found with devel/coccinelle. Reviewed by: bde (previous version - all new bugs are mine)
