Depsgraph: Cleanup, use DEG_NODE_CLASS prefix for node classes

Depsgraph: Cleanup, use DEG_NODE_TYPE prefix for depsgraph node types

Depsgraph: Remove unused argument from time source query

Depsgraph: Remove subgraph nodes

Those were never finished nor used. Again, starting from clean
state before we go into more complicated details.

Depsgraph: Remove dead code

Was never used or worked on in ages, if any of this code is
needed in the future it'll need to be redone anyway.

Depsgraph: Remove dead code from add_time_source()

This was never finished or done or used, no reason to keep it.
Better to simplify things before adding complexity of overrides
and copy-on-write.

Depsgraph: Cleanup, get rid of relation type

It was never actually used apart from being stored at a construciton time.
This caused some redundancy and ncertanty about which relation type to use
during construciton (often existing types were not close enough to particular
use case).

Cleanup: use row() sub-layout to expand enum properties horizontaly

Fix error for ghost icon in palette

THe ghost icon was not working with new draw manager because the check was not migrated.

GPUCodegen: fix missing ViewMatrix in new shading.

Fix blenderplayer build (ED_object_facemap*)

Merge remote-tracking branch 'origin/blender2.8' into custom-manipulators

new "Handle" option for convert to keyframes, if set calculates handles to be auto or vector(adaptive), but can be slower

Gawain: Optimize shader uniform access

Before this change Gawain was doing list lookup twice,
doing string comparison of every and each input which
is not efficient and not friendly for CPUs with small
cache size.

Now we store hash of input name together with actual
name and compare hashes first. Additionally, we do
everything in a single pass which is much better from
cache coherency point of view.

This brings Eevee cache population time from 80ms to
60ms on my desktop and from 800ms to 400ms for Clement
when navigating in a file from T50027.

Differential Revision: https://developer.blender.org/D2697

Fix T51687: GPUmat evaluation of shader tree would crash uppon unknown/unsupported socket types.

Made this resilient to unknown types, for now. Supporting specific INT
sockets (through implicit conversion to GPU_FLOAT ones) is considered nice TODO.

Merge branch '28' into custom-manipulators

Correct select-similar end value

Cleanup comment

Small cleanup. Cleared every unconnected changes and fixed some minor ui bugs.
