Andre Mauricio Zelak 600ad549b5 Use time traceable flag in HA clock selection 
A new time traceable flag was added to pmc agent to store the current
time traceable status.

This flag replaces the utc_offset_traceable flag in the HA clock
selection algorithm and status command.

Test plan: HA clock selection algorithm
PASS: Verify the clock source which time isn't traceable is discarded
by the algorithm if ha_gm_timeTraceable is enabled.
PASS: Verify the clock source which time is traceable isn't discarded
by the algorithm if ha_gm_timeTraceable is enabled.

Regression: status command
PASS: Verify the response of status command shows the correct GM time
traceable.

The 'valid sources' command is used to get a list of interfaces which
the clock is matching the requirements. The response contains a space
separated list of interfaces, or "None" when not a single clock is
matching all the requirements.

Test plan: valid sources command
PASS: Verify that a space separated list of interface is returned when
one or more clocks match the requirements.
PASS: Verify that the string "None" is returned when not a single clock
match the requirements.

Now the GM time traceable check is enabled by default as it is an
important check for both T-GM and T-BC scenarios.

The GM time traceable check is controlled in configuration by using
the ha_gm_timeTraceable setting, and it can be disabled using the
value 0 (ha_gm_timeTraceable 0).

Test plan: default value
PASS Verify the check is performed by default.
PASS Verify the user can disable the check by configuration.

Bonus:

Fixed the behavior when none clock is matching the requirements and the
active clock source is disabled using the 'disable source <interface>'
command. The interface is must be disabled and a new clock source is
selected.

Test plan: none clock is matching the requirements
PASS: Verify that the active source can be disabled and a new one is
selected.
PASS: Verify that an attempt to disable the last active interface
fails and an appopriated message is given as response.
PASS: Verify that the interface with higher priority is selected after
re-enabling it.
PASS: Verify the active clock source doesn't change if another
interface is disabled.
PASS: Verify the active clock source doesn't change if another
interface is re-enabled.

Subject: [PATCH 48/54] HA domain number
Support multiple domain numbers for each uds socket used in HA phc2sys.
The ha_domainNumber option is an interface setting to configure the domain
number for an uds socket. It ranges from 0 to 127. If the ha_domainNumber
is not configured for a given interface, the global domainNumber setting
is used.
Test plan:
PASS: Verify use of ha_domainNumber configuration in manual configuration.
Failure path: domain number match
PASS: Verify that phc2sys fails to start if domain number
doesn't match ptp4l instance parameter.
Regression:
PASS: Verify use of global domain number in manual configuration.
PASS: Verify auto configuration uses global domain number.
