Sebastian Huber 5b34e7ada4 IMFS: Improved support for generic nodes

The rtems_filesystem_location_info_t::node_access_2 was unused by the
IMFS.  Use it to hold the context of generic nodes.  This makes it
possible to use node handlers for objects with and without a
corresponding file system node.

For example network sockets created with socket() have only a file
descriptor, but no corresponding file system node.  The UNIX(4) domain
sockets can be bound to file system nodes.  In both cases the
rtems_filesystem_location_info_t must provide a pointer to the socket
structure used by the socket node handlers.  With the context pointer
(for sockets, this is the socket structure) in
rtems_filesystem_location_info_t::node_access_2 the same node handlers
can be used in both cases.

This directory contains for the "file system" library. All supported
file systems live under this tree.

Currently the supported file systems in this library are:

- IMFS or In Memory File System

   This is the only root file system on RTEMS at the moment. It supports
   files, directories, device nodes and mount points. It can also be
   configured to be the miniIMFS.

- TFTP and FTP filesystem are part of the libnetworking library.

- DEVFS or Device File system

- DOSFS, a FAT 12/16/32 MSDOS compatible file system.

- NFS Client, can mount NFS exported file systems.

- PIPE, a pipe file system.

- RFS, The RTEMS File System.
