Add <uchar.h>. The <uchar.h> header, part of C11, adds a small number of utility functions for 16/32-bit "universal" characters, which may or may not be UTF-16/32. As our wchar_t is already ISO 10646, simply add light-weight wrappers around wcrtomb() and mbrtowc(). While there, also add (non-yet-standard) _l functions, similar to the ones we already have for the other locale-dependent functions. Reviewed by: theraven

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.

Fix <uchar.h> in for C++11. It turns out that in C++11, char16_t and char32_t are built-in types; language keywords. Just fix this by putting traditional _*_T_DECLARED blocks around the definitions. We'll just predefine these in <sys/_types.h>. This also opens up the possibility to define char16_t in other header files, if ever needed (e.g. if we would gain a <ctype.h> for char16_t/char32_t).
