These sys/cdefs.h are not needed. Purge them. They are mostly left-over
from the $FreeBSD$ removal. A few in libc are still required for macros
that cdefs.h defines. Keep those.

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

Restore the augmented strlen commentary2021-02-08T19:15:21ZMateusz Guzikmjg@FreeBSD.org2021-02-07T19:53:34Zurn:sha1:3acea07c1873b1e4042f4a4fa8668745ee59f15b

Revert "Reimplement strlen"2021-02-03T19:38:10ZMateusz Guzikmjg@FreeBSD.org2021-02-03T19:38:10Zurn:sha1:33f0540b13d949c7cc226a79927ddc2062ff98bf
This reverts commit 710e45c4b8539d028877769f1a4ec088c48fb5f1.
It breaks for some corner cases on big endian ppc64.
Given the stage of the release process it is best to revert for now.

Reimplement strlen2021-01-29T23:48:26ZMateusz Guzikmjg@FreeBSD.org2021-01-29T21:48:11Zurn:sha1:710e45c4b8539d028877769f1a4ec088c48fb5f1
The previous code neglected to use primitives which can find the end
of the string without having to branch on every character.
While here augment the somewhat misleading commentary -- strlen as
implemented here leaves performance on the table, especially so for
userspace. Every arch should get a dedicated variant instead.
In the meantime this commit lessens the problem.
Tested with glibc test suite.
Naive test just calling strlen in a loop on Haswell (ops/s):
$(perl -e "print 'A' x 3"):

after: 338626619
$(perl -e "print 'A' x 100"):

libc: further adoption of SPDX licensing ID tags.2017-11-25T17:12:48ZPedro F. Giffunipfg@FreeBSD.org2017-11-25T17:12:48Zurn:sha1:d915a14ef094c8dfc1a5aee70e135abfec01d0f1
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.
