* BEntry::GetStat() and BNode::GetStat() used sizeof(struct stat) for the kernel

Browse Source 
syscall, but they could not know if R5 code called them (in which case the stat
  size has a different size). We now always only return the R5 stat structure here.
  This fixes bug #420. We might want to find a different solution to this problem,
  though.
* Be got SYMLINK_MAX wrong - it's not the maximum number of links (that's SYMLOOP_MAX),
  but the maximum size of a symlink buffer. Added missing SYMLOOP_MAX and SYMLINK_MAX
  constants to limits.h.
* Fixes MAXSYMLINKS to use SYMLOOP_MAX, instead of SYMLINKS_MAX (which doesn't exist
  in POSIX specs, but we (intentionally) break source compatibility here).
* Reenabled the Haiku versions of stat(), fstat(), and lstat() when build for Haiku.
* Removed OpenBeOS namespace stuff from the files I touched.
* Removed superfluous StorageDefs.Private.h, whyever that ended up in a public header
  is beyond me.
* Cleanup.
