Only tag relations update when new f-curve was allocated. This solves
possible too slow keyframe insertion when doing character animation,
but still does proper relation update when new ID component became
animated.
Add the necessary colors and/or alpha components to the theme instead.
Also switch the background for ordinary channels to use the likely
intended theme option, instead of the window background color.
The general rule is that the channel color is drawn full strength in the
channel list on the left, and with alpha in the actual key frame area on
the right. This alpha is also reused with bone group colors.

Computation of hold blocks was done by storing ranges (with start and
an end, and likely overlapping) in a tree keyed only by the block start.
This cannot work well, and there even were comments that it is not
reliable in complex cases.
A much better way to deal with it is to split all ranges so they don't
overlap. The most thorough way of doing this is to split at all and every
known keyframe, and in this case the data can actually be stored in the
key column data structures, avoiding the need for a second tree.
In practice, splitting requires a pass to copy this data to newly added
keys, and the necessity to loop over all keyframes in the range being
added. Both are linear and don't add excess algorithmic complexity.
The new implementation also calls BLI_dlrbTree_linkedlist_sync for
its own needs, so the users of the *_to_keylist functions don't have
to do it themselves anymore.

The automatic highlighting of constant curve areas was checking that
the bezier handles are horizontal even if a non-bezier interpolation
mode was active. Conversely, it was highlighting based on just handles
with Elastic interpolation, which always generates movement.
Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.

Recently @sergey found that hard-coding evaluation of certain very
common driver expressions without calling the Python interpreter
produces a 30-40% performance improvement. Since hard-coding is
obviously not suitable for production, I implemented a proper
parser and interpreter for simple arithmetic expressions in C.
The evaluator supports +, -, *, /, (), ==, !=, <, <=, >, >=,
and, or, not, ternary if; driver variables, frame, pi, True, False,
and a subset of standard math functions that seem most useful.
Booleans are represented as numbers, since within the supported
operation set it seems to be impossible to distinguish True/False
from 1.0/0.0. Boolean operations properly implement lazy evaluation
with jumps, and comparisons support chaining like 'a < b < c...'.
Expressions are parsed into a very simple stack machine program
that can then be safely evaluated in multiple threads.

Add tool options to control how select operates (add/sub/set/and/xor).
Note: edit mode armature select still needs to support all options,
this is complicated by how it handles partial end-point selection.
This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
By popular demand, the CLean Keyframes operator will now
leave handles and other interpolation settings untouched.
Previously, it would recreate the keyframes from scratch,
keeping only the frame + value, under the assumption that
the handle information was "bad" (i.e. the source of bumps
and roughness, due to bad hand tweaking). However, since
most animators use this on hand-keyed animation instead of
motion-capture data, this assumption didn't hold, and was
actually overly destructive - wiping out lots of hand-adjusted
curve data.
