afs: Add support for RENAME_NOREPLACE and RENAME_EXCHANGE
Add support for RENAME_NOREPLACE and RENAME_EXCHANGE, if the server
supports them.
The default is translated to YFS.Rename_Replace, falling back to
YFS.Rename; RENAME_NOREPLACE is translated to YFS.Rename_NoReplace and
RENAME_EXCHANGE to YFS.Rename_Exchange, both of which fall back to
reporting EINVAL.
