CMake: Remove stray WITH_JACK in full configuration

Build: change CMake option defaults to match "make full"

Previously some important features like OpenSubdiv were disabled by default,
which caused confusion.

The purpose of disabling some of these features was to avoid potentiall build
errors on Linux. But with precompiled libraries, install_deps.sh and better
library availability checking this is hopefully not much of a problem anymore.

This makes "make full" obsolete, but it's kept to not break docs or shell
scripts that people may have, and the .cmake config file remains useful to
modify an existing build folder.

This also changes some option to only be available on platforms where they
are actually supported (WITH_JACK, WITH_TBB_MALLOC_PROXY and X11 options).

Fix T71990: Apply bone transform results differ in edit/object mode

When negative scaled matrices were used, the roll calculation
didn't match, when calling Armature.transform().

Fix T71147 Eevee stops rendering after selection attempt

This is caused by the fallback path used by OSX, which is reconfiguring
the same default VAO. But it seems to be an issue on certain drivers.

Tests: Blendfile-loading test class

This new test class minimally sets up Blender so that it can load blend
files and construct a depsgraph without crashing.

Note that it hasn't been tested on very complex blend files, so it may
still crash when the loaded blend file references/requires uninitialised
data structures.

The test will certainly crash with Blend files created with Blender
older than 2.80, as the versioning code requires space types to be
registered. This is normally done by initialising the window manager,
which is not done in this test. The WM requires Python to run, which in
turn requires that Blender finds the release directory in the same
directory that contains the running executable, which is not the case
for GTest tests (they are written to `bin/tests/executablename`.

Fix crash if OptiX context creation fails in Cycles

When encountering an error during context creation, the "OptiXDevice" constructor aborts early.
This means the "cuda_stream" vector is never resized and the destructor iterated over non-existent data.

Fix (unreported) broken python resgistrable classes checks logic.

Logic for registering and checking properties of registrable classes was
broken, allowing to ignore some errors.

Recent fix rBeb798de101a `broke` the result of the
pyapi_idprop_datablock test, because previously that test would fail
(i.e. suceed, as it is an 'expected to break test') for a reason it was
not designed to check.

This is the problem with that kind of tests - you cannot really check
that they are failing on the expected reason(s)...

Console: remove shortcuts from console splash

Fix assert in Cycles memory statistics when using OptiX on multiple GPUs

The acceleration structure built by OptiX may be different between GPUs, so cannot assume the memory size is the same for all.
This fixes that by moving the memory management for all OptiX acceleration structures into the responsibility of each device (was already the case for BLAS previously, now for TLAS too).

Buildbot: Migrate package archive format for Linux from tar.bz2 to tar.xz

xz compresses 25% better than bz2, reducing download times and server load.
The numbers:

blender-2.80-linux-glibc217-x86_64.tar.bz2 (release): 134 886 174 bytes
with xz: 96 181 604 bytes (-28.7%)
with xz -9: 93 871 548 bytes (-30.4%)

blender-2.81-7c1fbe24ca33-linux-glibc217-x86_64.tar.bz2 (beta): 173 600 363 bytes
with xz: 133 100 664 bytes (-23.3%)
with xz -9: 129 534 124 bytes (-25.4%)

xz also decompresses more than twice as fast as bz2, however compression needs
four times as long (on my 7-year-old laptop 3-4 minutes instead of <1).

Also xz has become more common than bz2, e.g. Debian/Ubuntu deb packages have
been xz-compressed for years, so the dpkg package manager as well as systemd
and grub all depend on liblzma being present, whereas bz2 is becoming more and
more optional.

Current Linux archives also include the UID/GID of whatever user account
happens to be used for building by the blender.org infrastructure. If someone
then installs these archives as root e.g. to /usr/local/... and doesn't pay
full attention the files remain owned by a regular user, which is a serious
security issue. This patch fixes that by setting the UID/GID to 0.

EEVEE: Viewport Renderpasses

This patch will allow the user to select the EEVEE renderpass to be
shown in the viewport by default the combined pass will be shown.

Limitations:

* Viewport rendering stores the result in a `RenderResult`. RenderResult
is not aware of the type of data it holds. In many places where RenderResult
is used it is assumed that it stores a combined pass and the display+view
transform are applied.

I will propose to fix this in a future patch. But that is still being
designed and discussed.

Cycles: Scale denoising albedo contribution of Principled BSDFs according to average fresnel

The Principled BSDF uses Microfacet closures that include a fresnel term,
which are a special case since their weight tends to be near white even
if their average contribution is fairly low.

The sample weight is scaled by the average fresnel weight to account for
this, but the denoising albedo still used the unscaled weight.

This was fine for the original denoiser, but apparently OIDN can't handle
the resulting albedo pass well. Therefore, this commit adds the described
scaling to the albedo pass contribution as well.

This problem was described in T69770.

Fix T71000: Statistics don't take collections hidden state into account

Simple fix, to mimic what we had pre-local collections. So this is not
fully representative of the current load of the scene.

I started a more complex route where we literally just count objects
that are visible (taking object type restriction, local collections,
local view, ...). But in the end it is a bit overkill considering that
we have plans to change the statistics.
