Since a lot of the underlying machinery uses the same fields move those into a new file_lock_core, and embed that inside struct file_lock. For now, add some macros to ensure that we can continue to build while the conversion is in progress.

Convert the appropriate API calls to take struct file_lease instead, and convert the callers to use them. There is zero overlap between the lock manager operations for file locks and the ones for file leases, so split the lease-related operations off into a new lease_manager_operations struct.
