Improved auto-hiding of unused sockets for collapsed nodes.

Instead of generally hiding all unused sockets in collapsed mode, the sockets now have a new explicit flag SOCK_AUTO_HIDDEN, which is only toggled when the hide_toggle operator is called. This way the auto-hidden sockets stay as they are when nodes are duplicated etc. The new flag is necessary to distinguish between manually hidden sockets (via hide_sockets_toggle operator) and automatically hidden sockets and restore the node state when unhiding a node.

Fix for [#28978]
Disabling mode switching in panning in 2d as it is disabled in 3d also.
Apparently, it is a not good idea to call modal method from a modal method as the last won't be canceled.

Code cleanup

Removing some old + unused stuff that's not coming back. For example, the code
for the old "specials menu" used everywhere/all contexts.

Fix build break with double-definition of EXR stubs

A better solution would be to mark all function in openexr_multi.h as forceinline or static, but this change just fixes it to work for the reason trunk works: the header defining the stubs is only needs to be included in one .c file

Fix broken normals with mirror modifier

Fix for last commit, missed check for ob, could cause errors when object was removed.

More whitespace cleanup in python scripts

Whitespace cleanup in curve properties script

Fix #29568: Blender restores deleted scene

Special notifiers used for scene deletion which lead to undo pushes
after SCENE_OT_delete operator happening with scene still present in
the mainfile. That was a reason why operator redo used to restore
scene.

It's not so obvious why special notifier type is needed for scene
set and deletion -- it confuses undo system without having some
obvious advantages. Using "direct" scene deletion and setting
seems to be working fine so let's see if there'll be some issues
with this.

Move glTexEnvi to draw__start/draw__end.

As Campbell point, this is to avoid call glGet/glTexEnvi
on each character.

Tweaks for Node Header UI code:
* Don't show "New material" operator, when object type can't have materials
* Don't show "Use Nodes" for lamps in Blender Internal.

Fix #29743: Video sequencer wipe effect bug

Blur width used to be calculated quite strange depending on current angle.
Also, it used to be using wrong formula to calculate distance between
current point and boundary line which made blur width almost useless.

Now actual blur width is doesn't depend on angle and use corrected formula
for distance calculation which makes blur width slider behaves more
predictable.

This commit might make old files using wipe+blur be rendered a bit differently,
but don't think it's indeed issue because old behavior was crappy to setup
something useful so don't think this setup was used a lot.

use warnigns for all msvc configurations

Bumping up scons+msvc warning level to w1 so that we at least get some warnings
out of it.

Bugfix [#29806] World nodetrees not included in Animation Editor filtering

This was mostly only a problem when using Cycles, where NodeTrees are used to
control the world settings.

Also needed to knock out a few remnants of some bygone attempted optimisation
attempts which were preventing this from working (i.e. if a world block didn't
have any animdata, it's child nodetree would never get seen/tested). These
worked ok in the past, but are not that flexible for extension.

rename
* CDDM_calc_edges --> CDDM_calc_edges_tessface
* CDDM_calc_edges_poly --> CDDM_calc_edges

Cycles / Nodes:
* Make it possible to add a new material from the Node header, if no material exists in the (active) material slot.

3DView / Properties Region:
* Simplify UI inside the Transform Orientation Panel.
