TAKE 959978 - growing an XFS filesystem by more than 2TB is broken

[David Chinner]

Make growfs work for amounts greater than 2TB

The free block modification code has a 32bit interface, limiting
the size the filesystem can be grown even on 64 bit machines.
On 32 bit machines, there are other 32bit variables in transaction
structures and interfaces that need to be expanded to allow this
to work.
