df57947f08 spdx: initial adoption of licensing ID tags.
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.

Initially, only tag files that use BSD 4-Clause "Original" license.

e08c3b7c11 EUC-type encodings don't have single byte characters >= 128
This change should not be MFCed until new collate will be
MFCed first, because our old EUC tables have some hacks for
missing codesets.

d8ed03efe5 locales: Fix eucJP sorting (broken upstream?)
Sorting eucJP text with "sort" resulted in an illegal sequence while
"gsort" worked.  This was traced back to mbrtowc handling which was
broken for eucJP (probably eucCN, eucKR, and eucTW as well).  This
small fix took hours to figure out.  The OR operation to build the
wide character requires an unsigned character to work correctly.  The
euc wcrtowc conversion is probably broken upstream in Illumos as well.

Triggered by: misc/freebsd-doc-ja in ports (encoded in eucJP)

3c87aa1d3d Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter.  Also
adds support for per-thread locales.  This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

367ed4e13d The problem is: currently our single byte ctype(3) functions are broken
for wide characters locales in the argument range >= 0x80 - they may
return false positives.

Example 1: for UTF-8 locale we currently have:
iswspace(0xA0)==1 and isspace(0xA0)==1
(because iswspace() and isspace() are the same code)
but must have
iswspace(0xA0)==1 and isspace(0xA0)==0
(because there is no such character and all others in the range
0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte
range because our internal wchar_t representation for UTF-8 is UCS-4).

Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may
return false positives (must be 0).
(because iswalpha() and isalpha() are the same code)

This change address this issue separating single byte and wide ctype
and also fix iswascii() (currently iswascii() is broken for
arguments > 0xFF).
This change is 100% binary compatible with old binaries.

e94c6cb4a2 . Static'ize functions exported via function reference variables only.
. Replace inclusion of sys/param.h to sys/cdefs.h and sys/types.h where
  appropriate.
. move _*_init() prototypes to mblocal.h, and remove these prototypes
  from .c files
. use _none_init() in __setrunelocale() instead of duplicating code
. move __mb* variables from table.c to none.c allowing us to not to
  export _none_*() externs, and appropriately remove them from mblocal.h

ddc1eded85 Prefix the names of members of _RuneLocale and its sub-structures
with ``__'' to avoid polluting the namespace. This doesn't change the
documented rune interface at all, but breaks applications that accessed
_RuneLocale directly.

c05bd9ae25 Buffer partial wide characters more efficiently: instead of storing the
multibyte representation in conversion state objects, store the
accumulated wide character, set number and number of bytes remaining
to avoid having to derive them every time mbrtowc() is called.

02f4f60ad5 Convert the Big5, EUC, MSKanji and UTF-8 encoding methods to implement
mbrtowc() and wcrtomb() directly. GB18030, GBK and UTF2 are left
unconverted; GB18030 will be done eventually, but GBK and UTF2 may just
be removed, as they are subsets of GB18030 and UTF-8 respectively.

76692b8025 Rewrite locale loading procedures, so any load failure will not affect
currently cached data.  It allows a number of nice things, like: removing
fallback code from single locale loading, remove memory leak when LC_CTYPE
data loaded again and again, efficient cache use, not only for
setlocale(locale1); setlocale(locale1), but for setlocale(locale1);
setlocale("C"); setlocale(locale1) too (i.e.  data file loaded only once).

eb12e52a25 Remove the hard-coded limit of 3 bytes for EUC encodings.
Satoshi NIIMI-san kindly explained that EUC does not limit the byte length to
any arbitrary number.

We now set the limit to the maximum octet length of the codeset and it is
locale-specific.
