[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] 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.

GFS2: Fix up system xattrs This code has been shamelessly stolen from XFS at the suggestion of Christoph Hellwig. I've not added support for cached ACLs so far... watch for that in a later patch, although this is designed in such a way that they should be easy to add.

fs: take the ACL checks to common code Replace the ->check_acl method with a ->get_acl method that simply reads an ACL from disk after having a cache miss. This means we can replace the ACL checking boilerplate code with a single implementation in namei.c.

GFS2: Clean up ACLs To prepare for support for caching of ACLs, this cleans up the GFS2 ACL support by pushing the xattr code back into xattr.c and changing the acl_get function into one which only returns ACLs so that we can drop the caching function into it shortly.
