[GFS2] Clean up inode number handling
This patch cleans up the inode number handling code. The main difference is that instead of looking up the inodes using a struct gfs2_inum_host we now use just the no_addr member of this structure. The tests relating to no_formal_ino can then be done by the calling code. This has advantages in that we want to do different things in different code paths if the no_formal_ino doesn't match. In the NFS patch we want to return -ESTALE, but in the ->lookup() path, its a bug in the fs if the no_formal_ino doesn't match and thus we can withdraw in this case.
In order to later fix bz #201012, we need to be able to look up an inode without knowing no_formal_ino, as the only information that is known to us is the on-disk location of the inode in question.
This patch will also help us to fix bz #236099 at a later date by cleaning up a lot of the code in that area.
There are no user visible changes as a result of this patch and there are no changes to the on-disk format either.

[GFS2] Tidy up meta_io code
Fix a bug in the directory reading code, where we might have dereferenced a NULL pointer in case of OOM. Updated the directory code to use the new & improved version of gfs2_meta_ra() which now returns the first block that was being read. Previously it was releasing it requiring following code to grab the block again at each point it was called.
Also turned off readahead on directory lookups since we are reading a hash table, and therefore reading the entries in order is very unlikely. Readahead is still used for all other calls to the directory reading function (e.g. when growing the hash table).
Removed the DIO_START constant. Everywhere this was used, it was used to unconditionally start i/o aside from a couple of places, so I've removed it and made the couple of exceptions to this rule into separate functions.
Also hunted through the other DIO flags and removed them as arguments from functions which were always called with the same combination of arguments.
Updated gfs2_meta_indirect_buffer to be a bit more efficient and hopefully also be a bit easier to read.

[GFS2] Update copyright, tidy up incore.h
As per comments from Jan Engelhardt <jengelh@linux01.gwdg.de> this updates the copyright message to say "version" in full rather than "v.2". Also incore.h has been updated to remove forward structure declarations which are not required.
The gfs2_quota_lvb structure has now had endianess annotations added to it. Also quota.c has been updated so that we now store the lvb data locally in endian independant format to avoid needing a structure in host endianess too. As a result the endianess conversions are done as required at various points and thus the conversion routines in lvb.[ch] are no longer required. I've moved the one remaining constant in lvb.h thats used into lm.h and removed the unused lvb.[ch].
I have not changed the HIF_ constants. That is left to a later patch which I hope will unify the gh_flags and gh_iflags fields of the struct gfs2_holder.

gfs2: Wipe jdata and ail1 in gfs2_journal_wipe, formerly gfs2_meta_wipe Before this patch, when blocks were freed, it called gfs2_meta_wipe to take the metadata out of the pending journal blocks. It did this mostly by calling another function called gfs2_remove_from_journal. This is shortsighted because it does not do anything with jdata blocks which may also be in the journal. This patch expands the function so that it wipes out jdata blocks from the journal as well, and it wipes it from the ail1 list if it hasn't been written back yet. Since it now processes jdata blocks as well, the function has been renamed from gfs2_meta_wipe to gfs2_journal_wipe. New function gfs2_ail1_wipe wants a static view of the ail list, so it locks the sd_ail_lock when removing items. To accomplish this, function gfs2_remove_from_journal no longer locks the sd_ail_lock, and it's now the caller's responsibility to do so. I was going to make sd_ail_lock locking conditional, but the practice is generally frowned upon.

GFS2: Fix address space from page function Now that rgrps use the address space which is part of the super block, we need to update gfs2_mapping2sbd() to take account of that. The only way to do that easily is to use a different set of address_space_operations for rgrps.

GFS2: Merge gfs2_attach_bufdata() into trans.c The locking in gfs2_attach_bufdata() was type specific (data/meta) which made the function rather confusing. This patch moves the core of gfs2_attach_bufdata() into trans.c renaming it gfs2_alloc_bufdata() and moving the locking into gfs2_trans_add_data()/gfs2_trans_add_meta() As a result all of the locking related to adding data and metadata to the journal is now in these two functions. This should help to clarify what is going on, and give us some opportunities to simplify in some cases. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

GFS2: Metadata address space clean up Since the start of GFS2, an "extra" inode has been used to store the metadata belonging to each inode. The only reason for using this inode was to have an extra address space, the other fields were unused. This means that the memory usage was rather inefficient. The reason for keeping each inode's metadata in a separate address space is that when glocks are requested on remote nodes, we need to be able to efficiently locate the data and metadata which relating to that glock (inode) in order to sync or sync and invalidate it (depending on the remotely requested lock mode). This patch adds a new type of glock, which has in addition to its normal fields, has an address space. This applies to all inode and rgrp glocks (but to no other glock types which remain as before). As a result, we no longer need to have the second inode. This results in three major improvements: 1. A saving of approx 25% of memory used in caching inodes 2. A removal of the circular dependency between inodes and glocks 3. No confusion between "normal" and "metadata" inodes in super.c Although the first of these is the more immediately apparent, the second is just as important as it now enables a number of clean ups at umount time. Those will be the subject of future patches. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

GFS2: Clean up of glops.c This cleans up a number of bits of code mostly based in glops.c. A couple of simple functions have been merged into the callers to make it more obvious what is going on, the mysterious raising of i_writecount around the truncate_inode_pages() call has been removed. The meta_go_* operations have been renamed rgrp_go_* since that is the only lock type that they are used with. The unused argument of gfs2_read_sb has been removed. Also a bug has been fixed where a check for the rindex inode was in the wrong callback. More comments are added, and the debugging code is improved too.
