[XFS] implement generic xfs_btree_increment
From: Dave Chinner <dgc@sgi.com>
Because this is the first major generic btree routine this patch includes
some infrastrucure, first a few routines to deal with a btree block that
can be either in short or long form, second xfs_btree_read_buf_block,
which is the new central routine to read a btree block given a cursor, and
third the new xfs_btree_ptr_addr routine to calculate the address for a
given btree pointer record.
[hch: split out from bigger patch and minor adaptions]
