a12a8a71bb Remove "All Rights Reserved" from Blender Foundation copyright code
The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.

The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.

However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.

This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:

    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This program is free software ...

This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.

d32d787f5f Clang-Format: Allow empty functions to be single-line
For example

```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```

becomes

```
OIIOOutputDriver::~OIIOOutputDriver() {}
```

Saves quite some vertical space, which is especially handy for
constructors.

2da7977e3e Depsgraph: Implement backtrace functionality
The goal is to make it easier to track down sources of errors during
the dependency graph builder.

With this change whenever a relation can not be added a trace to the
entity which requested the relation will be printed. For example:

```
Failed to add relation "Copy Location"
Could not find op_from: OperationKey(type: BONE, component name: 'MissingBone', operation code: BONE_DONE)

Trace:

Depth    Type                     Name
-----    ----                     ----
1        Object                   Armature.001
2        Pose Channel             Bone
3        Constraint               Copy Location
```

On an implementation detail traced places where `checkIsBuiltAndTag`
is called, with some additional places to help tracking pose channels,
constraints, and modifiers.

Further improvements in granularity are possible, but that could happen
as a followup development once the core part is proven to work.

An example of such improvement would be to have entries in the trace
which will indicate NLA and drivers building. Currently it might be
a bit confusing to see IDs in the trace referenced from driver.

Even with such limitation the current state of the patch brings a
very valuable information (some information is much better than no
information at all).
