d8cc8fcf7f Refactor: Move color space information to ImBuf buffers
Before this change the ImBuf struct had dedicated fields for the
buffer data. Now the color space is stored inside of the struct
which wraps around the buffer information.

This only changes the field placement, without changing the way
it is handled. In the future one might imagine that operations
like stealing buffer data should null-ify the buffer colorspace
pointer. Such changes would need to have more accurate thinking
before implementation.

Should be no functional changes.

87ff8ee09a Cleanup: disambiguate the term 'path'
Use filepath or dirpath, unless the contents might be either,
in that case note that the contents could be both.
Use `rna_path*` in some cases too.

c1bc70b711 Cleanup: Add a copyright notice to files and use SPDX format
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.

This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.

Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.

Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:

406cfd214a Refactor ImBuf buffer access
The goal is to make it more explicit and centralized operation to
assign and steal buffer data, with proper ownership tracking.

The buffers and ownership flags are wrapped into their dedicated
structures now.

There should be no functional changes currently, it is a preparation
for allowing implicit sharing of the ImBuf buffers. Additionally, in
the future it is possible to more buffer-specific information (such
as color space) next to the buffer data itself. It is also possible
to clean up the allocation flags (IB_rect, ...) to give them more
clear naming and not have stored in the ImBuf->flags as they are only
needed for allocation.

The most dangerous part of this change is the change of byte buffer
data from `int*` to `uint8_t*`. In a lot of cases the byte buffer was
cast to `uchar*`, so those casts are now gone. But some code is
operating on `int*` so now there are casts in there. In practice this
should be fine, since we only support 64bit platforms, so allocations
are aligned. The real things to watch out for here is the fact that
allocation and offsetting from the byte buffer now need an explicit 4
channel multiplier.

Once everything is C++ it will be possible to simplify public
functions even further.

6b9a500a3a Cleanup: disambiguate terms "name", "file" & "str" / "string"
- Rename name/filename/path to filepath when it's used for full paths.
- Rename name/path to dirpath when it refers to a directory.
- Rename file to filepath or path (when it may be a file or dir).
- Rename ImBuf::name & anim::name to filepath.

1f96fa1129 Cleanup: rename BLI_make_existing_file for clarity
Rename BLI_make_existing_file to BLI_file_ensure_parent_dir_exists.
The previous name read as if it would make (touch) the file,
where as it ensures the directory component of the path exists.

Move from BLI_path to BLI_fileops as path utilities should only
manipulate paths and not deal with file IO creation
(this has more in common with BLI_file_touch for e.g.).

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.

0d945fe20e Fix deprecation warnings about printf() on macOS
The new Xcode 14.1 brings the new Apple Clang compiler which
considers sprintf unsafe and geenrates deprecation warnings
suggesting to sue snprintf instead. This only happens for C++
code by default, and C code can still use sprintf without any
warning.

This changes does the following:

- Whenever is trivial replace sprintf() with BLI_snprintf.
- For all other cases use the newly introduced BLI_sprintf
  which is a wrapper around sprintf() but without warning.

There is a discouragement note in the BLI_sprintf comment to
suggest use of BLI_snprintf when the size is known.

302b04a5a3 VSE: Improved Retiming system
Patch implements better way to control playback speed than it is
possible to do with speed effect. Speed factor property can be set in
Time panel.

There are 2 layers of control:

Option to retime movie to match scene FPS rate.
Custom speed factor to control playback rate.
Since playback rate is strip property, it is now possible to manipulate
strip as normal one even if it is retimed.

To facilitate manipulation, some functions need to consider speed factor
and apply necessary corrections to strip offset or strip start. These
corrections may need to be float numbers, so start and offsets must be
float as well.

Sound strips now use speed factor instead of pitch. This means, that
strips will change length to match usable length. In addition, it is
possible to group movie and sound strip and change speed of meta strip.

7afcfe111a VSE: Make time operations self-contained
This patch makes it possible to manipulate strips without need to use
update functions to recalculate effect and meta strips.

Prior to this change function `SEQ_time_update_sequence` had to be used
to update mainly effects and meta strips. This was implemented in a way
that relied on sorted list of strips, which can't always be done and in
rare cases this approach failed.

In case of meta strips, `seqbase` had to be passed and compared with
"active" one to determine whether meta strip should be updated or not.
This is especially weak system that is prone to bugs when functions are
used by python API functions.

Finally, other strip types had startdisp` and `enddisp` fields updated
by this function and a lot of code relied on these fields even if strip
start, length and offsets are available. This is completely
unnecessary.

Implemented changes:
All effects and meta strips are updated when strip handles are moved or
strip is translated, without need to call any update function.

Function `SEQ_time_update_sequence` has been split to
`SEQ_time_update_meta_strip_range` and
`seq_time_update_effects_strip_range`. These functions should be only
used within sequencer module code. Meta update is used for versioning,
which is only reason for it not being declared internally.

Sequence fields `startdisp` and `enddisp` are now only used for
effects to store strip start and end points. These fields should be
used only internally within sequencer module code.
Use function `SEQ_time_*_handle_frame_get` to get strip start and end
points.

To update effects and meta strips with reasonable performance, cache
for "parent" meta strip and attached effects is added to
`SequenceLookup` cache, so it shares invalidation mechanisms.
All caches are populated during single iteration.

There should be no functional changes.

c434782e3a File headers: SPDX License migration
Use a shorter/simpler license convention, stops the header taking so
much space.

Follow the SPDX license specification: https://spdx.org/licenses

- C/C++/objc/objc++
- Python
- Shell Scripts
- CMake, GNUmakefile

While most of the source tree has been included

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
  use different header conventions.

doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

See P2788 for the script that automated these edits.

8ad2642c47 Cleanup: use "filepath" term for Main, BlendFileData & FileGlobal
Use "filepath" which is the current convention for naming full paths.

- Main use "name" which isn't obviously a file path.
- BlendFileData & FileGlobal used "filename" which is often
  used for the name component of a path (without the directory).
