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: lib: use appropriate format specifier to print message iterator class

Running

  babeltrace2 --debug /some/trace

... results in the following crash:

    ==31705==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000000 (pc 0x7f5b9c25ae22 bp 0x7ffc64114490 sp 0x7ffc64113ba8 T0)

 ...

This is due to an object being printed with the wrong format specifier.
`C` is for component class objects, use `I` instead, since we are
printing a message iterator object.

Propagate error from packet_seek in case of truncated packet

Report the error all the way up allowing users/scripts to perform error
detection and act on it.

Print to stderr the truncated packet information for easier
identification.

Introduce bt_packet_seek_error enum for specific error handling.

Use the ERANGE errno for error propagation inside bt_iter_next and
ctf_read_event.

gcc warning fix: -Wextra

For the "ordered comparison of pointer with integer zero" warning, fix
this by comparing (type) -1 against (type) 0 instead of just 0, so if
"type" is a pointer type, this pointer type will be applied to the right
operand too, thus fixing the warning.
