Bump sys_errlist size to keep ABI backward-compatible for some time.
General further adoption of SPDX licensing ID tags.2017-11-20T19:49:47ZPedro F. Giffunipfg@FreeBSD.org2017-11-20T19:49:47Zurn:sha1:8a16b7a18f5d0b031f09832fd7752fba717e2a97
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.
libc: Always use our own copy of sys_errlist and sys_nerr (.so only).2013-08-31T22:32:42ZJilles Tjoelkerjilles@FreeBSD.org2013-08-31T22:32:42Zurn:sha1:e73151eb827122b6da662018d051ba8f58ef7e82
This ensures strerror() and friends continue to work correctly even if a
(non-PIE) executable linked against an older libc imports sys_errlist (which
causes sys_errlist to refer to the executable's copy with a size fixed when
that executable was linked).
The executable's use of sys_errlist remains broken because it uses the
current value of sys_nerr and may access past the bounds of the array.
Different from the message "Using sys_errlist from executables is not
ABI-stable" on freebsd-arch, this change does not affect the static library.
There seems no reason to prevent overriding the error messages in the static
library.
Renumber clauses to reduce diffs to other versions2013-05-28T20:57:40ZEd Masteemaste@FreeBSD.org2013-05-28T20:57:40Zurn:sha1:3fb3b97c4d38990da5f45b37e48a5110b3e9bc58
NetBSD, OpenBSD, and Android's Bionic number the clauses 1 through 3,
so follow suit to make comparison easier.

Allow strerror(0) and strerror_r(0, ...).2011-04-05T21:56:05ZJilles Tjoelkerjilles@FreeBSD.org2011-04-05T21:56:05Zurn:sha1:2973057493524c8b729d4c85e077f111012a4aac
Of course, strerror_r() may still fail with ERANGE.
Although the POSIX specification said this could fail with EINVAL and
doing this likely indicates invalid use of errno, most other
implementations permitted it, various POSIX testsuites require it to
work (matching the older sys_errlist array) and apparently some
applications depend on it.
