The cache manager refreshes volume location information every
two hours. If during a refresh the communication with the
vldb server fails, the previously known volume location information
should continue to be used.
The previous behavior in which the volume location information
is discarded first and then the update is performed can result
in unnecessary client failures when a temporary disruption in
communication with the vldb server occurs. Instead, wait until
we have a successful response from the vldb server before the
previous server list is discarded.

Thread safety in rx_NewCall requires that only one thread be
actively allocating or recycling a call at a time. Since we are
no longer holding the conn_call_lock across the entire transaction
we need to have another synchronization mechanism. Add a new
rx_connection flag, RX_CONN_MAKECALL_ACTIVE, which when set indicates
that a thread is actively obtaining a call. If any other threads
see this flag set, they will wait until being signalled that the
thread has completed its activity.
In addition, because the call->lock may be dropped when processing
rxi_ResetCall(), we must hold a reference to the call once we
begin using it. Otherwise, the call may be garbage collected
behind our back.

The attached patch has the client perform a GetCapabilities RPC
on fileservers it encounters.
It uses an additional server flag bit to keep track of the servers that
have been queried already.
In the case of afs_CeckServers(), GetTime RPCs are largely replaced by
GetCapabilities. GetTime is performed on a server if and only if
afs_setTime is nonzero and either
(a) no setTimeHost has yet been determined or
(b) the server in question has been designated as setTimeHost
The GetServers() function could thus be simplified even further wrt. the
setTime mechanism, but doing so would imply more rewriting (violating
the KISS principle; a followup patch should deal with that).
When a client is asked to reset callback states, it also resets the
"capabilites known" bit.
Thanks go to Simon Wilkinson, Jeffrey Altman and Jeffrey Hutzelman for
input regarding logic and implementation details.
