Syslinux - Mar 2009 - [PATCH 2/3] COM32 API: Correct readdir(), opendir(), closedir() and dirent.h

From: Gene Cumm <gene.cumm at gmail.com>

COM32 API: Correct readdir(), opendir(), closedir() and dirent.h;
Forgot some includes in opendir.c, closedir.c and readdir.c.
readdir() now loads DX into d_mode then the quick translate to d_type.

Signed-off-by: Gene Cumm <gene.cumm at gmail.com>

Depends on the patch I just submitted about changing from d_type in DL
to st_mode in DX.
