        * libcsupport/Makefile.am: Add mount-mgr.c.
        * libcsupport/src/mount-mgr.c: New.
        * include/rtems/fs.h: Added rtems_filesystem_location_mount.
        * libcsupport/include/rtems/libio.h, libcsupport/src/mount.c: New
        mount interface. It is similar to Linux.
        * libcsupport/include/rtems/libio_.h: Remove the
        init_fs_mount_table call.
        * libcsupport/src/base_fs.c: Remove init_fs_mount_table_call. Use
        the new mount call. Remove setting the root node in the global
        pathloc. Mount does this now.
        * libcsupport/src/privateenv.c: Remove the hack to set the root
        mount table entry in the environment.
        * libcsupport/src/unmount.cL Free the target string.
        * libblock/src/bdpart-mount.c: New mount API.

        * libfs/src/devfs/devfs.h, libfs/src/devfs/devfs_init.c,
        libfs/src/dosfs/dosfs.h, libfs/src/dosfs/msdos.h,
        libfs/src/dosfs/msdos_init.c, libfs/src/imfs/imfs.h,
        libfs/src/imfs/imfs_eval.c, libfs/src/imfs/imfs_init.c,
        libfs/src/imfs/miniimfs_init.c,
        libfs/src/nfsclient/src/librtemsNfs.h,
        libfs/src/rfs/rtems-rfs-rtems.c, libfs/src/rfs/rtems-rfs.h,
        libnetworking/lib/ftpfs.c, libnetworking/rtems/ftpfs.h,
        libnetworking/rtems/tftp.h: New mount_h API.

        * libfs/src/devfs/devfs_eval.c: Local include of extern ops.
        * libfs/src/nfsclient/src/nfs.c: New mount API. Removed the mount
        me call and fixed the initialisation to happen when mounting.

        * libmisc/Makefile.am, libmisc/shell/shellconfig.h: Remove mount
        filesystem files.

        * libmisc/fsmount/fsmount.c, libmisc/fsmount/fsmount.h: Updated to
        the new mount table values.

        * libmisc/shell/main_mount_ftp.c,
        libmisc/shell/main_mount_msdos.c, libmisc/shell/main_mount_rfs.c,
        libmisc/shell/main_mount_tftp.c: Removed.

        * libmisc/shell/main_mount.c: Use the new mount API. Also access
        the file system table for the file system types.

        * libnetworking/lib/tftpDriver.c: Updated to the new mount
        API. Fixed to allow mounting from any mount point. Also can now
        have more than file system mounted.

        * sapi/include/confdefs.h: Add file system configuration support.
