80dfb7bb3f gst: Use memcpy() instead of strncpy() where appropriate
strncpy() is assumed to be for strings so the compiler assumes that
it will need an extra byte for the string-terminaning NULL.

For cases where we know it's actually "binary" data, just copy it
with memcpy.

We're not really interested in our own packets and ignore them anyway.

215cfcf993 gstreamer: Fix memory leaks when context parse fails
When g_option_context_parse fails, context and error variables are not getting free'd
which results in memory leaks. Free'ing the same.

And replacing g_error_free with g_clear_error, which checks if the error being passed
is not NULL and sets the variable to NULL on free'ing.

1ae38f7ba7 ptp: Check for the actual API we use instead of just looking for __APPLE__
Should fix the build on FreeBSD, DragonFly and other BSDs.

f02de0e9a1 ptp-helper: Make sure to use g_poll() for the main context
The modified main context from https://bugzilla.gnome.org/show_bug.cgi?id=741054
somehow calls setugid(), which abort()s setuid root applications on OSX.

3af74817c1 ptp: Don't use SIOCGIFHWADDR on Apple
Just #ifdef the code for now, this should be implemented around
IOKit later instead of using ioctls.

8d77759834 ptp: Initial implementation of a PTP clock
GstPtpClock implements a PTP (IEEE1588:2008) ordinary clock in
slave-only mode, that allows a GStreamer pipeline to synchronize
to a PTP network clock in some specific domain.

The PTP subsystem can be initialized with gst_ptp_init(), which then
starts a helper process to do the actual communication via the PTP
ports. This is required as PTP listens on ports < 1024 and thus
requires special privileges. Once this helper process is started, the
main process will synchronize to all PTP domains that are detected on
the selected interfaces.

gst_ptp_clock_new() then allows to create a GstClock that provides the
PTP time from a master clock inside a specific PTP domain. This clock
will only return valid timestamps once the timestamps in the PTP domain
are known. To check this, the GstPtpClock::internal-clock property and
the related notify::clock signal can be used. Once the internal clock
is not NULL, the PTP domain's time is known. Alternatively you can wait
for this with gst_ptp_clock_wait_ready().

To gather statistics about the PTP clock synchronization,
gst_ptp_statistics_callback_add() can be used. This gives the
application the possibility to collect all kinds of statistics
from the clock synchronization.
