UI: use BLF_width_to_strlen for efficient text clipping

BLF API: Add BLF_width_to_strlen,rstrlen gives a byte offset from a string width

Fix T37826: Opening a new image in the image editor

Cast dimensions to size_t before multiplication.
Also made add_ibuf_size survive cases when image
buffer allocation failed.

Make compression in IMB_allocImBuf match other places

Missing NULL-pointer check in BKE_image_free_anim_ibufs

Fix T37827: cycles XML mesh export utility not longer worked.

Fix typo in previous own commit (thanks to _FrnchFrgg_ for noticing this!).

Editmesh: skip allocating a face array for recalc-normals

Minor optimization for strlen and memcpy calls for reading blend files

Summary:
This commit removes ~10000 strlen calls and ~100000 memcpy calls in blender (profiled with blender --background), ~10000 memcpy calls in makesdna.

There is no need to create null-terminated strings for atoi, because it converts only the initial portion of the string anyway.
Also it was noticed that DNA_elem_array_size and arraysize functions work only with full strings, so there is no point to calculate strlen.

Fix T37816: make cycles panel registration work better with addons.

This would give an error when an addon removed a panel.

correct error in recent commit

Fix T37810: GLSL dither shader not working on OS X.

The GLSL function textureSize() is not supported here, only when we start using
OpenGL core profile will this work. For now check the supported GLSL version and
use a somewhat slower replacement.

Make libyaml-cpp-dev not-breaking case for deb-like distros, and colors for messages!

Curves: Skip 3dtext & 2d-curve filling when fill is set to 'None'

Otherwise was impossible to have unfilled curves unless extrude was set

Fix for recent regression in curve geometry panel poll

Fix bmesh compiler warning with OS X / clang.

Fix T37264: cycles CPU render had limited number of float images, bumped to 1024.

GPU is still limited to 5, but there's no good reason for the CPU to be limited.
