* 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.
