Implement support for Linux's RENAME_* flags (for renameat2). Aside from being quite useful for userspace (providing race-free ways to exchange paths and implement mv --no-clobber), they are used by overlayfs and are thus required in order to use overlayfs-on-ZFS. In order for us to represent the new renameat2(2) flags in the ZIL, we create two new transaction types for the two flags which need transactional-level support (RENAME_EXCHANGE and RENAME_WHITEOUT). RENAME_NOREPLACE does not need any ZIL support because we know that if the operation succeeded before creating the ZIL entry, there was no file to be clobbered and thus it can be treated as a regular TX_RENAME.
