Handle surrogate pairs in c16rtomb (bug 23794, DR#488, C2X).
The c16rtomb implementation has: // XXX The ISO C 11 spec I have does not say anything about handling // XXX surrogates in this interface. The DR#488 resolution, as applied to C2X, requires surrogate pairs to be handled here (so the first call returns 0 and stores the high surrogate in the mbstate_t, while the second call combines the surrogates, produces a multibyte character and returns the number of bytes written). This patch implements that. (mbrtoc16 already handled producing surrogates as output.) Tested for x86_64. [BZ #23794] * wcsmbs/c16rtomb.c (c16rtomb): Save first character of surrogate pair and return 0 in that case, and use saved character to interpret following character. * wcsmbs/tst-c16-surrogate.c: New file. * wcsmbs/Makefile (tests): Add tst-c16-surrogate.c. [$(run-built-tests) = yes] ($(objpfx)tst-c16-surrogate.out): Depend on $(gen-locales)
