Motivation:
The xrootd protocol supports two types of wait instructions
from server to client: kXR_wait, and kXR_waitresp. The first
tells the client to wait and retry the request; the second
says wait for further instructions, or timeout if you don't
receive them.
The latter is supported by a specific response class, but
the former is not, although the corresponding
client inbound message does exist.
Modification:
Add the class.
Result:
It is easier now for the server to tell the client to
wait and retry on its own. This also helps to
fix a bug in the door code.
