Also use CreateFileW to open files so that one can use exotic characters in paths. The library interface is not modified, but the code makes an assumption that paths passed to lmdb functions are encoded as UTF-8. The UTF-8 encoded paths are encoded to UTF-16 which is then passed to CreateFileW.

This patch is now in git mdb.master.

Needs cleanup:

utf8_to_utf16() ignores errors in malloc/MultiByteToWideChar(). utf8_to_utf16()'s callers ignore error returns.

utf8_to_utf16() can return EILSEQ, an errno code not listed in mdb_strerror(). It should return a Windows error code or a new MDB_<SOMETHING> code.

(LMDB returns LDMB codes or system error codes. The latter are errno codes on Unix and Windows codes on Windows - except mdb_strerror's hardcoded errno codes which we plan to get rid of.)
