[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: Rationalise header files Move the contents of some headers which contained very little into more sensible places, and remove the original header files. This should make it easier to find things. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

[GFS2] Make headers compile on their own As per Jan Engelhardt's comments, this should make all the headers compile on their own by including and/or declaring structures early. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

GFS2: Fix remount argument parsing The following patch fixes an issue relating to remount and argument parsing. After this fix is applied, remount becomes atomic in that it either succeeds changing the mount to the new state, or it fails and leaves it in the old state. Previously it was possible for the parsing of options to fail part way though and for the fs to be left in a state where some of the new arguments had been applied, but some had not.

Revert "GFS2: Fix use-after-free bug on umount" This reverts commit 78802499912f1ba31ce83a94c55b5a980f250a43. The original patch is causing problems in relation to order of operations at umount in relation to jdata files. I need to fix this a different way.
