win32: use our own dirent.h
The mingw-runtime implemenation of opendir, readdir and closedir
sets errno to 0 on success, something that POSIX explicitly
forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be
read due to EMFILE") introduce a dependency on this behaviour,
leading to a broken "git clone" on Windows.
compat/mingw.c contains an implementation of readdir, and
compat/msvc.c contains implementations of opendir and closedir.
Move these to compat/win32/dirent.[ch], and change to our own DIR
structure at the same time.
This provides a generic Win32-implementation of opendir, readdir
and closedir which works on both MinGW and MSVC and does not reset
errno, and as a result git clone is working again on Windows.
