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).

Copy & rename various jdata functions into dir.c. The plan
being that directory metadata format will not change although
the journalled data format for "normal" files will change.

This renames get_block to gfs2_get_block and makes it accessible
from outside ops_address.c.

The code in this file is no longer used as the rindex file is
now accessible to userspace, so can be read/written directly.

For some reason a function pointer was being passed through
the truncate code which only ever took one value. This removes
the function pointer and replaces it with a single call to
the function in question.

Since we'll need to pin data if we are going to journal it, then
I'm renaming this function to make it less confusing. It might also
be worth moving it into lops.c since there are no users outside that
file.

I'd like to be rid of these memory allocations entirely so far as is
possible. For the moment though, mark them GFP_NOFS to make them less
harmful.

Removing the gfs2_databuf structure and using gfs2_bufdata instead
is a step towards allowing journaling of data without requiring the
metadata header on each journaled block. The idea is to merge the
code paths for ordered data with that of journaled data, with the
log operations in lops.c tacking account of the different types of
buffers as they are presented to it. Largely the code path for
metadata will be similar too, but obviously through a different set
of log operations.

Passes the flag through to ensure that the correct log operations are
invoked when the flag is set.

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.

We don't need this ioctl, we can use stat() to gain the same
