Since a non-writer stream does not know the events that are

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

this event was emitted.

ir: refactor FT validation and resolving
This patch refactors the CTF IR field type validation and the
resolving of variant/sequence field types.
First, validation is completely decoupled from the objects
containing the field types. In other words, validation does not
know the exact event class, stream class, or trace in which the
field types to validate are or are supposed to be. Only field types
are given to the validation function, which is isolated in its
own file.
To make the life of the resolving engine easier, all scopes are
deep-copied before reaching it. This is done during the validation
process. This ensures that no two field types in the whole
hierarchy refer to the same object in memory. This greatly simplifies
the resolving process, while adding insignificant overhead since
this is only done once. The copies do not replace the original types
until we are sure that the object to be validated (event class, stream
class, or trace) is valid and will be frozen. When it is the case, a
valid flag is set, which avoids validating the object again in the
future when calling the same function. If the object is not valid,
then the copies of its field types are discarded, and the function
fails.
Validation is done at three important places:
* bt_ctf_event_create(): when creating an event, because we don't
want the user to obtain an event linked to an invalid event
class. It is possible to create an event from an even class
which has a parent stream class which has no parent trace. In
this case, no variant/sequence field type in all the field types
of the stream class and event class can be resolved to the
trace packet header field type.
* bt_ctf_stream_class_add_event_class(): when adding an event class
to a stream class AND when the stream class has a parent trace,
because in this case the whole hierarchy exists and everything
is frozen, so it makes sense that everything in there should be
valid. If the stream class has no parent trace yet, then the
validation will be done when adding it to a trace using the
following function. This is because the added event class could
contain a variant/sequence field type which resolves to a field
type of the trace packet header field type, contained in the trace
object.
* bt_ctf_trace_add_stream_class(): when adding a stream class to
a trace, because in this case both the trace and the stream
class will be frozen, and hence they should be valid because they
cannot be changed anymore.
The test_ctf_writer test is updated here to follow those changes. Since
the field types can be copied when calling one of the above functions,
we cannot create a field out of an original field type and then compare
its address to a field obtained from the created event or stream: we must
put the original field types and obtain the new ones from the event class
or stream class. The contents of field types are compared using
bt_ctf_field_type_compare() instead.

ir: validate field types on field creation
This patch removes the validation that is done when adding
fields to structure/variant field types, and when creating
array/sequence field types with specific element types. This
is needed because a variant with an unset tag type may be
created and thus exist in any of those compound types. This
variant will be resolved when the time comes.
A valid field type is still required when creating a concrete
field out of it and when serializing it.

BT_MOVE(): call bt_put(_dst)
It makes no semantical sense to move a reference from a variable
to another without first putting the destination, if it has one.
Otherwise this would be a lost reference, unless it was moved
elsewhere or put manually using bt_put() previously, which is why
BT_MOVE() should always be used for move semantics and BT_PUT() is
preferred to bt_put() to avoid this situation.

ir: add user byte order to integer/float types
The `byte_order` field of an integer/float field type gets
replaced by `BIG_ENDIAN` or `LITTLE_ENDIAN` if it's set to
0 (native) once the type becomes the descendant of a
trace. However, once this is set, there is no way to know
that the user intended this field type's byte order to be
native. The metadata string, for example, will never contain
a byte order set to `native` with this behaviour.
This patch adds a `user_byte_order` field to the internal
integer and floating point number field type structures. This
field is the one set by and returned to the user using the
CTF IR API. Internally, the declaration's `byte_order` field
is still used for caching the resolved byte order.
This patch also modifies bt_ctf_stream_class_set_byte_order()
so that it cannot fail. This is an internal, hidden function
which should not be called with invalid parameters. Assertions
are inserted to verify this.

Handle negative time and offset from Epoch
Handle cases where a trace have a negative offset from Epoch.
If Epoch is arbitrary (e.g. embedded system starting at 0, without any
network access), the "0" can be used as correlation point between
various components, and some components could start before the
correlation point. Therefore, especially in traces where the time is
meant to be shown in nanoseconds or cycles from the correlation point,
it also makes sense to have a negative time value.
It introduces API-breaking changes in the C and Python APIs, since we
need to be able to return negative time values, which were previously
used as errors (-1ULL).
The --offset and --offset-ns command line parameters can now take
negative offset (seconds and nanoseconds) values too.
The [sec.ns] format is used as fallback so we don't attempt to pass
a negative time value to POSIX time-formatting APIs.
This also fixes an inaccurate return value in an error path of
bt_ctf_event_populate_event_header().
