    mount command: remove local getport() implementation
    
    Eliminate local getport() implementation from utils/mount/network.c, as
    it is no longer used.

commit cc58ba0c98b2f687810a5af9e6185bcc5e855fb0
Author: Chuck Lever <chuck.lever@oracle.com>
Date:   Tue Dec 2 07:43:01 2008 -0500

    mount command: Replace clnt_ping() and getport() calls in   probe_port()
    
    Update the mount command's probe_port() function to call the new shared
    rpcbind query and RPC ping functions.  This provides immediate support
    for
    rpcbind v3/v4 queries, and paves the way for supporting AF_INET6 in the
    probe_bothports() path.

commit 14b0dae49afae3fcf05c19ae84829aeef2f6876e
Author: Chuck Lever <chuck.lever@oracle.com>
Date:   Tue Dec 2 07:40:16 2008 -0500

    mount command: Use nfs_error() instead of perror()
    
    So we can ensure that error output is directed appropriately, use
    nfs_error() instead of perror() in start_statd().

commit ea0473feffd8071216c96217df3202a8deed2c65
Author: Chuck Lever <chuck.lever@oracle.com>
Date:   Tue Dec 2 07:39:06 2008 -0500

    mount command: Use nfs_pmap_getport() in probe_statd()
    
    Repace the getport() and clnt_ping() calls in probe_statd() with their
    new shared equivalents.
