Error in last commit (broke release build)

BLI_assert: print a backtrace with the error

Add BLI_system_backtrace()

Cleanup: Shapekey: get rid of `ED_vgroup_object_is_edit_mode()`

It was doing exactly the same thing as `BKE_object_is_in_editmode_vgroup()`, tsst...

Alternate fix for T42619: NULL check in caller

Rather avoid paranoid style, (wm == NULL) is an exceptional case.

CMake: update lite config

Cleanup identation and fix a bad alignment issue in last commit

Fix T42619: python crash: bpy.context.screen.is_animation_playing

Numerical input for changing brush size, strenght or angle.

Patch by Martin Vykoukal, thanks!

This patch adds ability to change brush parameters with keyboard, which
is missing functionality from 2.4x.

Slight improvements to vgroup tooltips

Simplify function to get view vector in world space

Support dynamic loading of SDL libraries

This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.

We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

cmake/buildbot: make sure we build the full blender and cycles cuda binaries

Fix for last commit, accidentaly removed transparent shadows property.

ShapeKey: Cleanup of BKE_keyblock_convert/update code.

Mainly:
* Use 'for' loops instead of 'while' ones (saves many lines and regroup most loop handling on one line).
* Use float[3] pointers where possible.

Fix T35170: Undoing edit op on a basis shapekey could generate extra offset on its 'children'.

Based on investigation by sergey (Sergey Sharybin) and revzin (Grigory Revzin).

ShapeKeys: Add `BKE_keyblock_is_basis` to check whether a given keyblock is used a basis by others.

Also fix stupid debug-only error in previous commit.

Cleanup: rename `BKE_key_convert/update` to `BKE_keyblock_convert/update`.

We are handling a keyblock here, not a whole key(set). Names are alreay a bit confusing,
let's be consistent at least.

ShapeKey: Refactor a bit `BKE_key_convert_from_...`

Thing is, those functions always reallocate the whole keyblock's data mem,
while in some cases we already have right amount of elements, so we can just
copy over. Further more, `BKE_key_convert_from_offset`, despite its name,
was not making any check nor allocation on keyblock's data elements!

So split 'copy' operation itself in `BKE_key_update_from_...`,
where no mem checks/operations are performed (only an assert).

Only useful in sculpt mode currently, but will be used by fix for T35170 too.

OSX/cmake: set actual compilation date to macosx bundles, fix player bundle with lbiomp5 ( do we really need this in player? )
