Reapply 227753 (xlocale cleanup), plus some fixes so that it passes build universe with gcc. Approved by: dim (mentor)

include: General further adoption of SPDX licensing ID tags. 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.

#ifndef _XLOCALE_LOCALE_H

LC_*_MASK bit shifting order was partially broken from the initial commit time at year 2012. Only LC_COLLATE_MASK and LC_CTYPE_MASK are in the right order. The order here should match XLC_* from "xlocale_private.h" which, in turn, match LC_* publicly visible order from <locale.h> which determines how locale components are stored in the structure. LC_*_MASK -> XLC_* translation done as "ffs(mask) - 1" in the querylocale() and equivalent shift loop in the newlocale(), so mapped to some wrong components (excluding two mentioned above). Formally the fix is ABI breakage, but old code using those masks never works properly in any case. Only newlocale() and querylocale() are affected. MFC after: 7 days

Change the return type of freelocale(3) to void. Our version of this function currently returns an integer indicating failure or success, whereas POSIX specifies that this function has no return value. It returns void. Patch up the header, sources and man page to use the right type. While there, use the opportunity to simplify the body of this function. Theoretically speaking, this change breaks the ABI of this function. That said, I have yet to find any code that makes use of freelocale()'s return value. I couldn't find any of it in the base system, nor did an exp-run reveal any breakage caused by this change. PR: 211394 (exp-run)
