[GFS2] Add gfs2_internal_read()
Add the new external read function. Its temporarily in jdata.c even though the protoype is in ops_file.h - this will change shortly. The current implementation will change to a page cache one when that happens. In order to effect the above changes, the various internal inodes now have Linux inodes attached to them. We keep the references to the Linux inodes, rather than the gfs2_inodes in the super block. In order to get everything to work correctly I've had to reorder the init sequence on mount (which I should probably have done earlier when .gfs2_admin was made visible).
