	fields to indicate they are "handlers".

73f6236bc0 Patch from Eric Norum <eric@skatter.usask.ca> to eliminate external 
IO handlers scheme that was implemented originally just to support
sockets.  The file system IO switch is more general and works fine.

2d733c424b More general fix based on bug report and patch from Ian Lance Taylor 
<ian@airs.com> to fix this problem:

    There is a small bug in __rtems_close in c/src/lib/libc/libio.c.  It
    does not check whether the file descriptor it is passed is open.  This
    can cause it to make a null dereference if it is passed a file
    descriptor which is in the valid range but which was not opened, or
    which was already closed.

07a3253de2 Added base version of file system infrastructure. This includes a major 
overhaul of the RTEMS system call interface.  This base file system is
the "In-Memory File System" aka IMFS.

The design and implementation was done by the following people:

  + Joel Sherrill (joel@OARcorp.com)
  + Jennifer Averett (jennifer@OARcorp.com)
  + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com)
  + Kerwin Wade (wade@OARcorp.com)

PROBLEMS
========
  + It is VERY likely that merging this will break the UNIX port.  This
    can/will be fixed.

  + There is likely some reentrancy/mutual exclusion needed.

  + Eventually, there should be a "mini-IMFS" description table to
    eliminate links, symlinks, etc to save memory.  All you need to
    have "classic RTEMS" functionality is technically directories
    and device IO.  All the rest could be left out to save memory.
