Andre Mauricio Zelak deeacbcdf3 Redundant HA PTP timing clock sources support
Enhanced phc2sys to support multiple PTP timing clock sources, to
select the best clock source available according to the clocks
statuses.

A series of changes were patched back from a newer version of the
linuxptp package. They contain the support for multiple pmc nodes,
necessary to communicate with multiple ptp4l instances.

The phc2sys is now able to automatically select the best clock
according to the clocks statuses, and also monitors any clock
status change and act to keep the system synchronized to the
best clock source available.

A new set of configuration options were added to control the behavior
of the automatic clock selection algorithm and to configure the clock
source interfaces.

And a new command interface was added to phc2sys to gather statuses
about the clocks configured and the HA algorithm. This interface also
provides commands to control the clock source selection for debug and
maintenance proposes.

Test plan:
PASS: Verify the linuxptp package is built containing all the patches.
PASS: Verify the .deb package produced in the build install and that
all the PTP different deployments new and existing are OK.
PASS: Verify that a new image containing the linuxptp packed can be
installed and that all the PTP different deployments new and existing
are OK.

Subject: [PATCH 12/47] phc2sys: make PMC functions non-static
In preparation of a trivial movement of code to pmc_common.c, remove the
"static" keyword from the functions that will end up there, since they
will be still called from phc2sys.c for now.
