Shared libraries and USD plugins will be placed in the same folder, where USD
already looks for plugins.
This means that specifying the path to the plugins will no longer be needed
once the new libraries are available for all platforms. For now the code was
refactored to support both cases.
Ref T99618
* Support bidirectional type lookups. E.g. finding the base type of a
field was supported, but not the other way around. This also removes
the todo in `get_vector_type`. To achieve this, types have to be
registered up-front.
* Separate `CPPType` from other "type traits". For example, previously
`ValueOrFieldCPPType` adds additional behavior on top of `CPPType`.
Previously, it was a subclass, now it just contains a reference to the
`CPPType` it corresponds to. This follows the composition-over-inheritance
idea. This makes it easier to have self-contained "type traits" without
having to put everything into `CPPType`.

Replace the argument with an in ifdef in BKE_appdir_program_path_init.
At the time `blenkernel` didn't define WITH_PYTHON_MODULE, since it does
now there is no need for an argument. With the minor benefit of fewer
preprocessor checks in the main() function.
BKE_appdir_program_path_init would override the module path extracted
from the Python module, replacing it with the Python executable.
This caused the data files not to be found and the module not to load.
This is supposed to hold the latest improvement from the EEVEE rewrite branch.
Note that a restart is necessary in order for the engine to appear.
The registration code is a bit convoluted as it needs to be after the WM_init.

It it rather an old experiment now which didn't pay off.
The initial idea was to have main and jobs threads on fast
nodes of TR2 processors. This didn't really work reliably
because in Blender we need to be able to create nested
threads without their affinity set. This is not how some of
OS are creating nested threads, and we don't always have
access to child threads to reset their affinity.
So overall complexity of the initial idea implementation
became too much compared to the performance gain.
In almost all cases there is no difference between `G.relbase_valid`
and checking `G.main->filepath` isn't an empty string.
In many places a non-empty string is already being used instead of
`G.relbase_valid`.
The only situation where this was needed was when saving from
`wm_file_write` where they temporarily became out of sync.
This has been replaced by adding a new member to `BlendFileWriteParams`
to account for saving an unsaved file for the first time.

Suppressing the splash was only done when passing in an argument from
the command line.
Remove G.file_loaded, as it is misleading, only set once on startup,
replace with G.relbase_valid which is used everywhere else to check
if the file path should be used.
Allows to avoid a global lock being held while reading files from disk,
solving performance issues when Cycles needs to read a lot of packed
images.

TBBmalloc_proxy already takes care of any allocations
being done from MSVC compiled code, some of the dependencies
like GMP cannot be build with MSVC and we have to use
mingw to build them. mingw however links against the older
msvcrt.dll for its allocation needs, which TBBMallocProxy
does not hook.
GMP has an option to supply your own allocation functions
so we can still manually redirect them to TBBMalloc.

Sub-systems that use directories from BKE_appdir needed to be
initialized after parsing '--env-system-datafiles'.
This meant the animation player needed to call IMB_init it's self.
Avoid this complication by having a pass that can be used to setup
the environment before Blender's resources are accessed.
This reverts the workaround from 9ea345d1cf
This choice was made when preferences were not read in background mode,
so the temp dir needed to be initialized with something.
See bc9848f7e6.
Now preferences are always read there is no reason to ignore this
particular preference in background mode.
Anyone wanting to do background renders that ignore their preferences
can run with factory startup.
Initialize ImBuf (and color-management) after passing arguments
that set environment variables such as `--env-system-datapath`
This also fixes a bug where BKE_appdir logging failed since it was
called before the `--log` argument was passed.
Add asserts so this doesn't happen again.
Initialize the USD library when used (instead of at startup), so that
this can happen inside the IO/USD module. This makes calls to the USD
library local to Blender's USD code.
Note that failure to find the USD JSON files will now only be reported
when the USD exporter is used, and not on every startup of Blender.
This is the first step in cleaning up the way Blender patches and
initialises the USD library.
Manifest Task: https://developer.blender.org/T80320
As creator.c is used for the 'main' function,
avoid obscure declarations being placed so prominently.
- Move Blender as a Python module declarations into it's own section.
- Move USD declaration to an 'extern' just before it's called.
The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
When definining static variables that own memory, you should
use the "construct on first use" idiom. Otherwise, you'll get
a warning when Blender exits.

When picking a small tile size when doing a CLI render will
yield many status updates being printed to the console
causing a slowdown in the render process. 2.79 with the
same amount of tiles did not have this slowdown.
The reason for this turned out to be a debugging aid added
in rBd2757d149bf2 which disabled buffering for stdout which
on windows caused every single character being printed to the
console to try to obtain a mutex, and worse the thread being
put to sleep when this mutex was unavailable leading to poor
performance.
This patch changes the behaviour by only disabling the
buffering in debug builds.
CLI render of the default cube with 16x16 tiles at 1080p
2.83 : 37.57s
now : 17.03s
note: this only affected CLI renders, renders from the UI
do not report this kind of information and had no such
slowdown.
This patch enables TBB as the default task scheduler. TBB stands for Threading Building Blocks and is developed by Intel. The library contains several threading patters. This patch maps blenders BLI_task_* function to their counterpart. After this patch we can add more patterns. A promising one is TBB:graph that can be used for depsgraph, draw manager and compositor.
Performance changes depends on the actual hardware. It was tested on different hardwares from laptops to workstations and we didn't detected any downgrade of the performance.
