[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] journal recovery patch This is one of the changes related to journal recovery I mentioned a couple weeks ago. We can get into a situation where there are only readonly nodes currently mounting the fs, but there are journals that need to be recovered. Since the readonly nodes can't recover journals, the next rw mounter needs to go through and check all journals and recover any that are dirty (i.e. what the first node to mount the fs does). This rw mounter needs to skip the journals held by the existing readonly nodes. Skipping those journals amounts to using the TRY flag on the journal locks so acquiring the lock of a journal held by a readonly node will fail instead of blocking indefinately.
