We unfortunately cannot fix this for previous versions of Blender, but
at least the issue (Blender crashing on unknown IDProp types) should now
be addressed for future.
Simply reset unknown IDProp types to integer one, and reset its value to zero.
Previously, every RenderPass would have a bitfield that specified its type. That limits the number of passes to 32, which was reached a while ago.
However, most of the code already supported arbitrary RenderPasses since they were also used to store Multilayer EXR images.
Therefore, this commit completely removes the passflag from RenderPass and changes all code to use the unique pass name for identification.
Since Blender Internal relies on hardcoded passes and to preserve compatibility, 32 pass names are reserved for the old hardcoded passes.
To support these arbitrary passes, the Render Result compositor node now adds dynamic sockets. For compatibility, the old hardcoded sockets are always stored and just hidden when the corresponding pass isn't available.
To use these changes, the Render Engine API now includes a function that allows render engines to add arbitrary passes to the render result. To be able to add options for these passes, addons can now add their own properties to SceneRenderLayers.
To keep the compositor input node updated, render engine plugins have to implement a callback that registers all the passes that will be generated.
From a user perspective, nothing should change with this commit.

Most of this was copying/adapting code from octahedral existing draw
code, tough part was to get BBone matrices to behave as expected, they
are using a fairly specific setup...
Addresses T51365 and T51362.
The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

Objects that were using the same lamp data were having the same display matrices.
This is fixed by allowing engine to store a memory block inside the object itself.
This moves selectability/visibility flag flush from some hardcoded
places in the code to depsgraph. This way it is possible to simply
tag depsgraph to update those flags and rest it'll do on its own.
Using depsgraph for such flush is an overkill: those flags are fully
static and can not be animated, so it doesn't really make sense to
hook only those to depsgraph.
However, in the future we will have overrides on collections, which
ideally would need to be animatable and drivable and easiest way
to support this is to do this on depsgraph level, so it ensures
proper order of evaluation for animation and drivers. And it seems
logical to do both overrides and flags flush from depsgraph from
this point of view.
This commit also includes the evaluation of IDProperty for collections,
which basically are just another form of override. So once we implement
the other kind of overrides the flushing and collection evaluation won't
change.

This should have been done earlier. But now that we may see more activity in master due to bcon3 merges, it is even more important to stress out the separation between master and 2.8.
Also I needed the version bump for idproperties doversion (they needed
to happen in _after_linking, and we don't have access to
DNA_struct_elem_find there).
Last but not least, every time I posted a video or image from 2.80, I
got someone confused about the version showing in the infobar.
First this replace a custom data struct with IDProperty, and use
IDProperty group merge and copying functions. Which means that a collection
property setting is only created if necessary.
This implements the "Layer Collection settings" override system, as
suggested in the "Override Manifesto" document.
The core is working, with Scene, LayerCollection and Object using a
single IDProperty to store all the render settings data. Next step is to
migrate this to depsgraph.
Note: Clay engine "ssao_samples" was hardcoded to 32 for now. It will come
back as part of "Workspace Settings" later.
Many thanks for Bastien Montagne for the help with the UI template
nightmare ;)

That one was:
* Resetting non-ID pointers (lib_link_xxx funcs should only affect ID
pointers, everything else shall be done in direct_link_xxx func).
* Even worse, always calling lib_link_animdata, even when
LIB_TAG_NEED_LINK tag was unset...
We do not need any special handling anymore for usercount of images used
by faces/polygons (tpage stuff), since we have the 'real_user' handling,
which will gracefully cope with all possible situations.
So better not keep that ugly confusing useless special case.
Mainly:
* Add missing `IDP_LibLinkProperty()` calls for many ID types
(harmless currently, but better be consistent here!).
* Bring lib_link_xxx functions more in line with each other.
* Replace some long if/else by switch.
For Windows 8.1 and X11 (Linux, BSD) now use the DPI specified by the operating
system, which previously only worked on macOS. For Windows this is handled per
monitor, for X11 this is based on Xft.dpi or xrandr --dpi. This should result
in appropriate font and button sizes by default in most cases.
The UI has been simplified to a single UI Scale factor relative to the automatic
DPI, instead of two DPI and Virtual Pixel Size settings. There is forward and
backwards compatibility for existing user preferences.

Instead of calling a function looping over whole list of a given ID
type, make whole loop over Main in parent function, and call functions
writing a single datablock at a time.
This design is more in line with all other places in Blender where we
handle whole content of Main (including readfile.c), and much more easy
to extend and add e.g. some generic processing of IDs before/after
writing, etc.
From user point, there should be no change at all, only difference is
that data-block types won't be saved in same order as before (.blend
file specs enforces no order here, so this is not an issue, but it could
bug some third party users using other, simplified .blend file reader maybe).

We concluded this is going to be the display mode users will need to work
with the most, so makes sense to make it the default one.
Also, if the opened file only has one collection in the active render
layer, we expand it (almost empty list would be misleading).
What I had to do to make the expanding work is a bit ugly, but didn't
find a better way. During do_version we don't have access to the
TreeElement instances, and including ED_outliner.h to share code here
should be avoided too.
Internal change needed for template support.
Loading the user preferences first so it's possible
for preferences to control startup behavior.
In general it's useful to load preferences before data-files,
so we know security settings for eg.
Talked with Pablo Vazquez (venomgfx) and Julian Eisel (Severin), and we came up with this solution instead.
Basically, if the file has only one layer, it is converted to a collection named "Default Collection". Otherwise we name the collections: "Collection 1 [converted from 2.75]"
This slightly changes SDef behavior, by now respecting object transforms
at bind time, thus not requiring the objects to be aligned in their
respective local spaces, but instead using world space.
There were some issues with how we store outliner tree elements:
Apparently the only removable elements have been data-blocks so far.
When recreating the TreeElements, their TreeStoreElem instances were
mainly identified by their ID pointer. However non-data-blocks mostly
depend on an index. For collections, such an index isn't a reliable
measure though if we want to allow removing items. Depending on it for
identifying the TreeStoreElem instance would cause some quite noticeable
glitches (wrong highlights, two elements sharing highlight, etc).
For now I've solved that by actually removing the TreeStoreElem that
represents the removed element. A little limitation of this is that
after undoing the removal, some information might get lost, like
flags to store selection, or opened/closed state.
A better solution that would also fix this issue would be having a real
unique identifier for each non-data-block element, like an idname or even
its data-pointer. Not sure if we can get those to work reliable with
file read/write though, would have to investigate...
Also added a general Outliner tree traversal utility.
Please never, ever use same DNA var for two different things. Even worse
if they do not have same type and ranges!
This is only ensuring issues (as described in report, but also if
animating both RNA props using same DNA var... yuck).
And we were not even saving any byte in DNA, could reuse some padding
there to store the two new needed vars (yes, two, since we cannot re-use
existing one if we want to keep backward *and* forward compatibility).
This prevents crashes when a file was saved with 2.8, but a new
engine settings property was created.
In those cases any previous collection settings are wiped out. We can do
an elegant merge soon.
