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).

This adds an extra argument to gfs2_trans_add_bh() to indicate whether the
bh being added to the transaction is metadata or data. Its currently unused
since all existing callers set it to 1 (metadata) but following patches will
make use of it.

We no longer allocate a dinode on the stack in init_dinode()
and we no longer use gfs2_dinode_out (eliminating one copy) and
gfs2_meta_header_in (eliminating another copy). The meta_header_in
fucntion is now no longer referenced from outside gfs2_ondisk.c, so
make it static.

This patch contains all the core files for GFS2.
