OpenGL: bump Windows to GL 3.3 compat profile

Part of T49012

Gawain: improve immediate mode performance

This was already fast on Apple, but @Severin and @dfelinto noticed slowdowns in user prefs, which is text heavy.

The problem was immBeginAtMost not being smart about VBO write flushing. immBeginAtMost can use all of its allocated range or only a subrange. The previous code was forcing back-to-back draw calls and buffer writes to serialize. This commit lets OpenGL know that our VBO writes never overlap, so there's no need to wait.

Should be much faster now!

Fix unitialized variable use

Own mistake in ae8e8454700.
Patch by @efi0ng, thanks!

Merge branch 'master' into blender2.8

OpenGL: draw node sockets more efficiently

1 or 2 draw calls per node instead of 1 per socket (inputs + outputs).
Rearranged draw order so we set uniforms less frequently.
Some style & dead code cleanup.

OpenGL: new built-in point shader, clean up other shader names

Smooth round point with outline (uniform color) and fill (varying color).

Updated shader naming scheme: a shader that doesn't deal with color does not have to say "no color". Vertex shaders do not have to say "uniform color" since their frag counterpart actually has the uniform. Each name should describe what that shader *does*, not what it *doesn't do*.

blender 2.8: OpenGL: node_circle_draw use now immediate mode

I use your new point shader to draw the node's soket

OpenGL: bump Linux to GL 3.3 compat profile

fall back to 3.0 if needed (during development)

fix pointer type warning

thanks, gcc

Outliner: Fix missing indentation for search-match highlight

Own mistake in ae8e84547005.

BLF: early exit when drawing empty strings

Avoids all kinds of setup & preparations to draw nothing.

BLF: fix crash on text input fields

Some strings have known length, others are NULL terminated (len = INT_MAX in this case).

Now font drawing knows to treat INT_MAX special.

Outliner: Draw highlights over entire row

Previously, highlights (mouse hover, selection, search-match) didn't affect background of restriction icons, now the entire line gets highlighted.

Outliner: Element mouse hover feedback

Some little UI polish to get familiar with outliner code (but also because it's a useful feature). Committing to blender2.8 branch but can also port to master (2.7) if wanted.

This basically causes the mouse hovered element to be highlighted. Contrast of the highlight should be fine, even with a non-default theme. Also did some minor cleanup.

Cycles: use near clipping distance in panorama camera.

viewport: draw non-mesh objects for a starter

This starts to decouple non-mesh objects and the legacy draw pipeline.
It shows how we can mix e.g., Cycles and lamps and empties.

viewport: move border drawing code to new file

immediate mode: convert render border code and move to new drawing
routine

Immediate mode: use new util functions, and border draw functions
