Subject: ocfs2: code cleanup: remove unused functions

These functions are either coded in individual files as static or not used
at all.  Remove them.

NAK - some of this may be used by userspace (ocfs2_fs.h is shared with
ocfs2-tools).

The other reason for my NAK is that some of these either complete a set of
functions or provide information on how to handle structures:
ocfs2_gd_is_discontig or ocfs2_system_inode_is_global are good examples and
it's all in ocfs2_fs.h which is where I'd personally go look to see how the
fs structures are stored.
