bindings: try importing collections.abc first for forward compatibility

Using the babeltrace Python module with Python 3.3-3.8 gives a warning:

/usr/lib/python3/dist-packages/babeltrace/babeltrace.py:811:
DeprecationWarning: Using or importing the ABCs from 'collections'
instead of from 'collections.abc' is deprecated since Python 3.3,
and in 3.9 it will stop working

Therefore, for forward compability (Python 3.9+), try importing it
using the new way first. Otherwise, fall back on the old way.

Fix: lttng-live format: do not error out on empty streams hang up

Attaching to a stream hung up before providing any trace packet
causes ctf_open_mmap_stream_read() to return an error.

This kind of scenario can happen with the upcoming "lttng clear"
feature.

Fix: lttng-live: ctf_live_packet_seek stream hang up handling

When get_next_index sets the index position to EOF,
ctf_live_packet_seek() should in turn set the stream position to EOF
to propagate the hung up state.

Fix: trace-collection: trace clock use after free

The trace collection should copy the trace clock object rather
than take a reference to the first trace's trace clock, because
it may be freed when the trace is removed (e.g. application going
away in per-pid live tracing).

Fix: lttng-live: use-after-free in get_next_index()

Running babeltrace under valgrind with a test-cases doing per-pid
lttng tracing in live mode triggers this use-after-free in
get_next_index() when stream is hung up.
