dir.h: direct::d_type

Browse source 
* dir.c (glob_helper): use d_type to reduce lstat system calls.
* win32/dir.h (struct direct): add d_type instead of d_isdir and
  d_isrep.  SYMLINKD is unreliable, since the target can be
  replaced after a link was created.
* win32/win32.c (readdir_internal): set d_type.
