Initial implementation of the debuginfo API

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`.

This introduces a dependency on `libelf` and `libdw` from
elfutils. The feature can be disabled at configure time with the
`--disable-debuginfo` flag.

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

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.

ir: rename bt_ctf_node -> bt_ctf_scope

"scope" is more conforming to the CTF nomenclature than "node".

Note that this changes the Babeltrace 1.x API, but this API is
expected to be hidden from the user starting from Babeltrace 2.
