fix Cygwin UTF-16 surrogate-pair handling with -i
grep -i would segfault on systems using UTF-16-based wchar_t (Cygwin)
when converting an input string containing certain 4-byte UTF-8
sequences to lower case. The conversions to wchar_t and back to
a UTF-8 multibyte string did not take surrogate pairs into account.
* src/searchutils.c (mbtolower) [__CYGWIN__]: Detect and handle
surrogate pairs when converting.
* NEWS (Bug fixes): Mention it.
* tests/surrogate-pair: New test.
* tests/Makefile.am (TESTS): Add it.
