pcp updates

Hi,

2nd crack a fixing the IB memory leak.
Also I think I fixed the problem with the clusterpmda and the IB
metrics.

I think this really highlights the fact that every PMDA that supports
being loaded via a local context should use unique names for its
variables, such as 'metrictab'.  I'll send in a patch soon that
addresses this problem with the ib PMDA.

    Fix memory leak in IB pmda
    
    Calling umad_get_port() repeatedly leaks memory because the pkeys
    structures are re-allocated each time.
    
    This adds the ca_name and portnum to the local_port_t to guard
against
    future versions of libibumad de-allocating either of those fields
during
    umad_port_release().

    Rename metrictab variable in cluster PMDA
    
    This avoids a symbol name clash when loading the IB PMDA
    via a local context.  The IB initialization routine was trodding
    over the cluster PMDA's metrictab.

    Don't modify domain in ibpmda_init()
    
    This is handled by pmdaInit() in the case where an alternate
    domain is specified via the commandline or dispatch->domain
