Fix: ctf-writer: null dereference in bt_ctf_trace_common_add_stream_class

gcc 12.1.0 reports that:
In file included from object-pool.h:38,
                 from clock-class.h:11,
                 from trace.c:27:
In function 'bt_ctf_object_set_parent',
    inlined from 'bt_ctf_object_set_parent' at object.h:102:6,
    inlined from 'bt_ctf_trace_common_add_stream_class' at trace.c:1227:3:
object.h:123:26: warning: null pointer dereference [-Wnull-dereference]
  123 | if (child->parent) {
      | ~~~~~^~~~~~~~
object.h:123:26: warning: null pointer dereference [-Wnull-dereference]

This can indeed happen if bt_ctf_trace_common_add_stream_class is called
with a nil stream class argument. A null check is added in the error
path.

Fix: src.text.details: use write_uint_prop_value to handle unsigned values in write_int_range

I tried creating an option field class with unsigned integer selector,
with a [1, UINT64_MAX] range. The details field class shows it as:

     opt_with_uint_sel: Option (unsigned integer selector) (Selector field location [Event payload: uint_selector]):
      Selector ranges: [1, -1]

The -1 is wrong. Fix two spots to call write_uint_prop_value instead of
write_int_prop_value.

After:

    opt_with_uint_sel: Option (unsigned integer selector) (Selector field location [Event payload: uint_selector]):
       Selector ranges: [1, 18,446,744,073,709,551,615]

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.
