Cleanup old tracker task format to the new. e.g: [#34039] to T34039
Ref D8718

Simplify code by replacing `if (strip) { everything; }` with
`if (strip == NULL) { return; }`.
No functional changes.

Currently, it's difficult to use the NLA system for users who are only
interested in using it as animation layers.
Entering tweak mode hides strips which are not evaluated. If the user
wanted to edit a different strip, they must exit tweak mode, look for
the strip, select it then re-enter tweak mode.
Solution:
All strips are always shown. The user can now see the next strip they
want to start editing.

Change the way Sync Length works so that it keeps keyframes at the same
key as before the sync. Now when the user exits tweak mode, the overall
NLA result is unchanged.

Now callbacks for animdata, nla strip and fcurve are in their own proper
BKE files (mimicking `foreach_id` callback of `IDTypeInfo`).
This commit also fixes some missing handling of ID pointers (text ID and
IDProperties of script fcurve modifier...).

Note that `BKE_library.h`/`library.c` were renamed to
`BKE_lib_id.h`/`lib_id.c` to avoid having a too generic name here.

Since we are already respecting the User Preference for 'auto_smoothing'
in 'BKE_nlastrip_validate_fcurves', we should also do this for default
interpolation and handles.

The default was changed with an initial implementation of the feature.
With the feedback from animators, having a behavior which affects curves
outside of a changing range is not convenient for professional animators
working on high quality character animation. On the other hand, automatic
smoothing is better for casual animation of object motion.
This change adds an ability to change the default via User Preferences.

A lot of areas were querying sound information directly using audio handle
which does not exist on an original sound IDs.
This change basically makes it so it's possible to query information about
given sound ID, without worrying about whether it's loaded or not: if it is
needed to load it first it happens automatically (no automatically-opened
handles are left behind though).
While this seems a bit extreme to open files on such queries it is still
better than the old situation when all sound handles were opened on file
load, no matter if it's needed or not. Besides, none of the changed code
paths are performance critical, just handful of tools.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

NLA strips are users of their action, so we need to pass along ID
management flags.
This commit also cleans up a bit things by passing along ID_CREATE/COPY
flags instead of dummy booleans...

It's been 9 years too long.
And don't get this one confused with nla.bake (why would you even?).
The·BakeAction operator will be renamed to NLA_TO_bake next.

Each AnimData block has a set of Blend/Extrapolation/Influence settings
that can be used to control how the active action is blended with the
NLA stack. However, these settings were not getting copied over to the
newly created strips (as the push-down code existed long before these
settings were added).
This commit solves this in several ways:
* Active Action Blend/Extrapolation/Influence settings now get copied
to the new strips when adding them to the NLA stack via Push Down.
Note: This doesn't happen when there are no existing NLA tracks,
as these settings don't get used in that case.
* Strip Influence will be copied across when inf < 1.0 (i.e. when a
non-default value is used), to maintain the effect. To make this work,
the influence value will get added as a keyframe to the strip's
"Influence" Control FCurve.
- See code comments for an alternative approach and why that was not chosen
- Strip Time still doesn't get keyframes added automatically yet.
* To ensure the "extrapolation mode" settings don't get always overwritten,
I've put in place a compromise: the extrapolation will only get changed
if the chosen setting will cause problmes (i.e. hold forward & back -> hold forward
if there are other tracks before it already).
Not safe for backporting to 2.79[x] stable releases.

The legacy algorithm only considers two adjacent points when computing
the bezier handles, which cannot produce satisfactory results. Animators
are often forced to manually adjust all curves.
The new approach instead solves a system of equations to trace a cubic spline
with continuous second derivative through the whole segment of auto points,
delimited at ends by keyframes with handles set by other requirements.
This algorithm also adjusts Vector handles that face ordinary bezier keyframes
to achieve zero acceleration at the Vector keyframe, instead of simply pointing
it at the adjacent point.
Original idea and implementation by Benoit Bolsee <benoit.bolsee@online.be>;
code mostly rewritten to improve code clarity and extensibility.

While such drivers will generally get evaluated too late to be of much
use during animations, it can still be useful to allow using drivers to
control a whole bunch of NLA strip properties (i.e. syncing NLA strip
timings via a single property/control).
Keyframe insertion however is still not allowed on these properties
(and an error message will now be displayed when trying to do so,
instead of silently failing), as it is useless.
