xfs: Add support to RENAME_EXCHANGE flag
Adds a new function named xfs_cross_rename(), responsible for handling requests from sys_renameat2() using RENAME_EXCHANGE flag.

xfs: Make xfs_vn_rename compliant with renameat2() syscall
To be able to support RENAME_EXCHANGE flag from renameat2() system call, XFS must have its inode_operations updated, exporting .rename2 method, instead of .rename.
This patch just replaces the (now old) .rename method by .rename2, using the same infra-structure, but checking rename flags. Calls to .rename2 using RENAME_EXCHANGE flag, although now handled inside XFS, still return -EINVAL.
RENAME_NOREPLACE is handled via VFS and we don't need to care about it inside xfs_vn_rename.
