Merge branch 'master' into blender2.8

Fix T50084: Adding torus re-orders UV layers.

Issue was indeed in join operation, mesh in which we join all others
could be re-added to final data after others, leading to undesired
re-ordering of CD layers, and existing vertices etc. being shifted away
from their original indices, etc.

All kind of more or less bad and undesired changes, fixed by always
re-inserting destination mesh first.

Also cleaned up a bit that code, it was doing some rather
non-recommanded things (like allocating zero-sized mem, doing own
coocking to remove a data-block from main, etc.).

install_deps.sh: don't use backticks

The script complained that it could not find the executable "--build-all".

OpenGL immediate mode: transform_snap.c and part of drawnode.c

Also converted ED_node_draw_snap from drawnode.c
Committing these together, as they are inter-dependent.

Fix T50524: Basis shapekey editing while rendering bug.

Root of the issue was BM_mesh_bm_to_me() breaking application of basis
offset to 'child' shapekeys, when called more than once from same BMesh.

install_deps.sh: don't use backticks

The script complained that it could not find the executable "--build-all".

Fix T50497: prop_search not correctly drew in UI (D2473)

Fix T50535: Cycles render segfault when Explode modifier before hair particle modifier + UV material

Tricky issue caused by CDDM_copy() coying MFACE array but not MTFACE which
confused logic later on.

Now we don't copy ANY tessellation unless it is requested to.

Thanks Bastien for help and review!

fix build: BLF Theme color

blenderplayer uses BLF but not Editor UI, so we got a link error for the missing UI_GetThemeColor function.

Moved the new function from BLF to UI.

Add GetThemeColorBlendShade3ubv function

Differential Revision: https://developer.blender.org/D2484

Used by part of T49043

BLF can use Theme colors

For anything fancier than regular Theme colors (shading, alpha, etc.) do this:

unsigned char color[4]
UI_GetThemeColor[Fancy]4ubv(... color)
BLF_color4ubv(fontid, color)

That way the BLF color API stays simple.

set default color for BLF fonts

Set to an annoying bright color so we can see where to add BLF_color calls.

add BLF_color functions

Needed a way to pass main font color to BLF without using obsolete glColor. Could not use immUniform since BLF binds its shader internally.
