[Gerrit Code Review]

The following commit has been merged in the master branch:
commit 523d39f020f551e59b0f369c8480fa13b90db277

    Fileserver capabilities support for the UNIX client
    
    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.
