pmdalinux: add kernel.percpu.intr count metric
Turns out pcp-mpstat(1) needs per-CPU interrupt counts, which
are most easily calculated here and exported in a similar way
to kernel.all.intr. The mpstat changes to use this should be
following from Sitaram shortly.

qa/865 and 866 (new): exercise the new PM_ERR_TIMOUT protocols
865 uses the (Perl version of the) slow PMDA.
866 uses new fault injection services in libpcp_fault.

src/libpcp: make the pmcd-client protocol safer in the presence of timeouts
If a timeout occurs on a PDU read (in __pmGetPDU) the libpcp callers
are now responsible for closing the channel that connects pmcd and all
contexts associated with that pmcd in the current client app.
Because this channel maybe multiplexed between contexts, a timeout
introduces the possibility that incorrect PDUs are seen by other
contexts and this breaks the synchronous communication between pmcd
and a PMAPI context, or worse, delivers incorrect data to other PMAPI
contexts.
This change prevents that from happening, but the other contexts
will need to call pmReconnectContext() before they can resume sending
and receiving PDUs to and from the pmcd that triggered the original
timeout condition.

src/libpcp/src/pdu.c: add fault injection check for __pmGetPDU()
If the class PM_FAULT_TIMEOUT has been armed, return immediately
with PM_ERR_TIMEOUT.
Note this generates no code for the regular libpcp, it is only
enabled in libpcp_fault.

qa/381: at last, problem identified
This test has been failing intermittently for some time and I've
finally tracked it down ... the logic assumed that the primary logger
was handling pmlc requests on port 4330. This is true most of the
time (test passes) but sometimes (especially with pmmgr in the mix)
may not be so (test fails).
