Fix T49104: normal problem in imported Alembic objects

Recompute the normals if the normals are supposed to be varying (e.g. in
the ISchema).

Alembic import: fix scene min/max time computation to take objects with
transform animations into account.

Fix T49081: Alembic sampling times are not taking start frame into
account.

This resulted in animations always starting at frame 0.

Fix/add some tooltips to 'Object Align' operator options.

Fix Bevel crashes T49088 and T48858.

Was calling the fast path for finding edge order in cases
where it should not have been called.

Cycles: Fix regression where smoke wouldn't show in renders

Fix T49102: Angle option of new GP brush settings is too restricted in value

Now the range is between -90 to 90 degrees to give more customization
options.

Fix T49086: UV Along Stroke can be set as vector input for environment texture

CMake: Move main platform checks to separate files

Basically title says it all.

The goal is to make platform maintenance easier, so you don't have
to constantly scroll back and forth looking for if() branches to
check which exact platform you're currently working on.

Ideally we also would move option defaults to a platform files,
but that i'm not sure how to implement in a nice way yet.

More UI messages fixes and cleanup.

2D stabilizer: Cover rotation tracks label with enabled flag

2D stabilizer: Use exact getter instead of regular one followed with frame check

2D stabilizer: Remove check for markers count in the track

This would be a real disaster if track has no markers, which we should
not masquerade and detect such weird cases as soon as possible.

2D stabilizer: Remove redundant rows from the interface

2D stabilizer: One more occurrence of len() in the drawing code

2D Stabilizer: Use more consistent RNA naming for properties

Annoying i did not notice this originally, but for RNA we need to keep
things as much consistent as possible.

2D Stabilzier: Don't use len() for checking whether something is enabled or not

This code runs on every redraw and iterates the whole tracks list, which
is something we should avoid.

Fix T49100: Replace old tooltip for GPencil brush iterations

GPencil: Change ruler line thickness to make it thicker

OpenGL: draw NDOF guide with new immediate mode

This is the rotation pivot guide for 3D mouse input.
