windows support: unicode filenames Windows uses a legacy codepage for char* / runtime functions accepting char *. Using UTF-8 as the codepage with setlocale() is explicitly forbidden. Work this around by overriding the MSVCRT functions with wrapper macros, that assume UTF-8 and use "proper" API calls like _wopen etc. to deal with unicode filenames. All code that uses standard functions that take or return filenames must now include osdep/io.h. stat() can't be overridden, because MinGW-w64 itself defines "stat" as a macro. Change code to use use mp_stat() instead. This is not perfectly clean, but still somewhat sane, and much better than littering the rest of the mplayer code with MinGW specific hacks. It's also a bit fragile, but that's actually little different from the previous situation. Also, MinGW is unlikely to ever include a nice way of dealing with this.

glob-win: support Unicode glob-win.c wasn't big, so it was easier to rewrite it. The new version supports Unicode, handles directories properly, sorts the output and puts all its allocations in the same talloc context to simplify the implementation of globfree. Notably, the old glob had error checking code, but didn't do anything with the errors since the error reporting code was commented out. The new glob doesn't copy this behaviour. It just treats errors as if there were no more matching files, which shouldn't matter for mpv, since it ignores glob errors too. To match the other Windows I/O helper functions, the definition is moved to osdep/io.h.

Use O_CLOEXEC when creating FDs This is needed so that new processes (created with fork+exec) don't inherit open files, which can be important for a number of reasons. Since O_CLOEXEC is relatively new (POSIX.1-2008, before that Linux specific), we #define it to 0 in io.h to prevent compilation errors on older/crappy systems. At least this is the plan. input.c creates a pipe. For that, add a mp_set_cloexec() function (which is based on Weston's code in vo_wayland.c, but more correct). We could use pipe2() instead, but that is Linux specific. Technically, we have a race condition, but it won't matter.

win32: get rid of mp_stat in the normal source code mp_stat() instead of stat() was used in the normal code (i.e. even on Unix), because MinGW-w64 has an unbelievable macro-mess in place, which prevents solving this elegantly. Add some dirty workarounds to hide mp_stat() from the normal code properly. This now requires replacing all functions that use the struct stat type. This includes fstat, lstat, fstatat, and possibly others. (mpv currently uses stat and fstat only.)
