For a long time we've always stored bmap btree records in the 64bit format,
so kill off the dead 32bit type, and make sure the 64bit type is named just
xfs_bmbt_rec everywhere, without any size postfix.

xfs_trans_iget is a wrapper for xfs_iget that adds the inode to the
transaction after it is read. Except when the inode already is in the
inode cache, in which case it returns the existing locked inode with
increment lock recursion counts.
Now, no one in the tree every decrements these lock recursion counts,
so any user of this gets a potential double unlock when both the original
owner of the inode and the xfs_trans_iget caller unlock it. When looking
back in a git bisect in the historic XFS tree there was only one place
that decremented these counts, xfs_trans_iput. Introduced in commit
ca25df7a840f426eb566d52667b6950b92bb84b5 by Adam Sweeney in 1993,
and removed in commit 19f899a3ab155ff6a49c0c79b06f2f61059afaf3 by
Steve Lord in 2003. And as long as it didn't slip through git bisects
cracks never actually used in that time frame.
A quick audit of the callers of xfs_trans_iget shows that no caller
really relies on this behaviour fortunately - xfs_ialloc allows this
inode from disk so it must not be there before, and all the RT allocator
routines only every add each RT bitmap inode once.
In addition to removing lots of code and reducing the size of the inode
item this patch also avoids the double inode cache lookup in each
create/mkdir/mknod transaction.

There are several tests for #ifndef HAVE_FORMAT32, but
this is never defined anywhere so it is always the default
behavior; just remove the ifndef goop.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
