TLV_PORT_PROPERTIES_NP carries, among other attributes, a timestamp type
used for that port. In order to make it possible to format the value for
user consumption, introduce a new function ts_str().

The two programs, phc2sys and phc_ctl, use nearly identical subroutines to
open an instance of a dynamic posix clock. In anticipation of yet a third
program with similar needs, this patch refactors the common code into the
utilities.

Currently the clockIdentity is generated from the mac address of the first
interface/port in config file. This patch add the possibility to set it in
config file.
The reason is if the stack is restarted with a different set of ports, it
may be circumstances when clockIdentity needs to be equal as before
restart even if the port setup is different.

The file, pmc.c, contains utility functions for printing out a port address
structure. We will want to call these functions from pmc_common.c, and so
this patch moves the utility functions where they belong.

The current implementation of ptp4l always assumes 6 octets MAC
address, which is correct for Ethernet interfaces but not for IPoIB
interfaces (that have 20 octets MAC), therefore running ptp4l over
IPoIB interface does not function correctly.
In Infiniband, every interface has three identifiers:
GUID, GID, and LID.
The GUID is similar in concept to a MAC address. From RFC4392:
The EUI-64 portion of a GID is referred to as the Global Unique
Identifier (GUID) and is the only persistent identifier of a port.
Therefore, to support IPoIB interfaces, the GUID of the port should
be used instead of the MAC.
This patch checks the interface type before creating the clock identity,
for Infiniband ports, it retrieves the GUID of the port using sysfs
and use it to create the clock identity.
sysfs method was chosen since the GUID is the 6 lsb bytes of
the 20 byte device address, and SIOCGIFHWADDR ioctl call returns
the 14 msb bytes of the device address, so it is not possible to
get the GUID using SIOCGIFHWADDR ioctl call.

The state machines in 1588 do not specify an event that causes a transition
out of the initializing state. This was left as a local issue. For this
transition, the current code assigns the next state outside of the FSM. But
doing so prevents an alternative FSM to handle this transition differently.
By introducing a new event, this patch places this transition where it
belongs, namely under the control of the FSM code,

Since size_t is an unsigned data type, it won't evaluate correctly on errors
of vasprintf(). This patch makes 'len2' a signed integer, as expected by
vasprintf().
'len2' is of type 'size_t' in util.c:451, but vasprintf in line
457 returns '-1' on error which is checked in line 460. Currently
this check will always fail (regardless of the return value of
vasprintf()), according to its declaration as unsigned int.

The raw Ethernet transport code invented its own way of storing the MAC
address into our "struct address" data structure. However, this private
format is incompatible with the sockaddr_ll returned from the networking
stack. This patch converts the code to use the proper format.

Add wrappers for malloc(), calloc(), realloc() and strdup() that check
if the allocation failed, print an error message and call exit(1). This
allows the caller to use the returned value without checking for errors.
This modifies all transports to use a new common address type, struct
address. This address is stored in a ptp_message for all received messages.
For sending, the "default" address is used with the default sending
functions, transport_send and transport_peer. The default address depends on
the transport; it's supposed to be the multicast address assigned by the
transport specification.
Later, a new transport_sendto function will be implemented that sends to the
address contained in the passed ptp_message.

This patch adds functions to get int, uint, double value from string
with error checking and range specification.
These functions don't allow overflow and outside of the range values.
In addition, it adds parser_result cases "MALFORMED" and "OUT_OF_RANGE" to make
reason of parse error more clear.

We already have a grand master state. Adding this event will simplify the
