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

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.

\class BFile
\brief BFile is a wrapper class for common operations on files providing
access to the file's content data and its attributes.
A BFile represents a file in some file system. It implements the
BPositionIO interface and thus the methods to read from and write to the
file, and is derived of BNode to provide access to the file's attributes.
