mount/fuse: add mount-option "enable-ino32" for the native client
By default the GlusterFS-native client uses 64-bit inodes. Some 32-bit applications can not handle these correctly. Introduce a client-side mount option "enable-ino32" which causes the FUSE-client to squash the 64-bit inodes into a 32-bit value.
