This patchset adds so_info and durin, which are used in debug info or
callsite analysis. The developer is expected to use the SO info API
documented in `include/babeltrace/so-info.h`. Durin is only used
internally by so_info as a wrapper around `libdw`.
The analysis itself is implemented in the new `lib/debuginfo.c`.

Fix: do not set event's parent to a non-writer stream
Since a non-writer stream does not know the events that are
associated to it, an event with a non-writer stream parent can
never be destroyed.
Fix this by setting a stream parent if the stream is a writer
stream, and otherwise by using the event's packet's stream.

ir: add bt_ctf_event_get_clock_value()
This patch adds a hash table of clocks to their current values (in
cycles) to the stream object. bt_ctf_stream_update_clock_value() can
be called to update the registered clock value of a given stream
from the current value of a given integer field, of which the type
is mapped to a clock. The function handles the case where the size of
the field is less than 64 bits and can make the current clock value
wrap once per call.
This patch also adds a similar hash table to the event object.
bt_ctf_event_register_stream_clock_values() is to be called by
internal code to take a snapshot of all the registered clock values
of the event's stream. The copied clock values can be retrieved by
the user later using bt_ctf_event_get_clock_value(), which should
return the value that a given clock had when the event was emitted.
This is intended to be used by sink components since the value
of a clock changes as events are created, whereas it is common
situation to hold an event and later need the clock values when
this event was emitted.

ir: make bt_ctf_stream_create() public
This patch also removes bt_ctf_trace_create_stream(), so that the
only way to create a stream in non-writer mode is using
bt_ctf_stream_create(). Only the stream class is needed, and since
it needs to be part of a trace before calling the function, the
created stream gets associated to this trace on creation.
The function also knows if the stream class's trace was created by
a CTF writer thanks to a new flag. With this, it's able to create
a stream file and set the stream's FD if it's a writer stream.
Otherwise the FD is set to -1 and this stream cannot be passed to
stream writer functions like bt_ctf_stream_append_event() and
bt_ctf_stream_append_discarded_events(), for example.
