Miroslav Lichvar cdd11b744b port: print bogus delay request message as rate limited info.
Upgrade the message level to info so the user can see it, but print it
at most once per 5 minutes to not spam the syslog too much.

Richard Cochran 2201345058 uds: restore delay mechanism to zero value.
The new configuration code inadvertently causes the UDS port to use P2P
messaging when P2P is set as a global option.  This results in a never
ending series of "missing timestamp" error messages from the UDS port as
it vainly tries to send peer delay requests.

This patch fixes the bug by changing the UDS delay mechanism back to zero
as it was before.  This is the appropriate setting for the UDS port,
because it never leaves the listening state and thus never sends an E2E
delay request.

Richard Cochran e85cb68320 Support hybrid E2E using unicast delay requests and responses.
The draft Enterprise Profile [1] specifies a hybrid E2E delay mechanism,
where the delay response message is sent "in kind".  That is, if the
request is unicast, then the response is also unicast.  Apparently this
scheme is already in widespread use in some industries.  Also, it makes
sense, because those messages are of no interest to the other slaves in
the PTP network.

Because of the address work already in place, in turns out that adding
this mode is almost trivial.  This patch introduces an "hybrid_e2e" option
that enabled the new mode.

Richard Cochran d0eb73c87b Use the standardized low level socket address format.
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.

Miroslav Lichvar e4325ee3fb util: add wrappers for memory allocation functions.
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.

Richard Cochran 0135e5344d port: constrain the master's logMinDelayReqInterval.

Richard Cochran a8a3ddec6a Fix integer overflow in the foreign master bookkeeping code.
The logMessageInterval field has an improbable range from 2^-128 to 2^127
seconds.  The extreme ends cause an integer overflow in the calculation
of the "foreign master time window".  Buggy or mis-configured foreign
masters advertising extreme values will cause incorrect announce message
aging.

This patch fixes the issue by adding thresholds for the bogus extremes.
