e04d7c49dc Fix buffer overflow vulnerabilities in mesh code. 
Solves these security issues from T52924:
CVE-2017-12081
CVE-2017-12082
CVE-2017-12086
CVE-2017-12099
CVE-2017-12100
CVE-2017-12101
CVE-2017-12105

While the specific overflow issue may be fixed, loading the repro .blend
files may still crash because they are incomplete and corrupt. The way
they crash may be impossible to exploit, but this is difficult to prove.

5614193745 Task scheduler: Use restrict pointer qualifier 
Those pointers are never to be aliased, so let's be explicit about this and hope
compiler does save some CPU ticks.

4c4a7e84c6 Task scheduler: Use single parallel range function with more flexible function 
Now all the fine-tuning is happening using parallel range settings structure,
which avoid passing long lists of arguments, allows extend fine-tuning further,
avoid having lots of various functions which basically does the same thing.

d2708b0f73 Task scheduler: Get rid of extended version of parallel range callback 
Wrap all arguments into TLS type of argument. Avoids some branching and also
makes it easier to extend things in the future.

a41fe949d8 Fix T53398: Surface deform modifier says that convex polygons are concave for big faces 
Dot-product for angle check need either to be divided by vectors magnitude or be
calculated for normalized vectors.

df76616d74 Usual UI/i18n message fixes. 
Please provide valid description for SurfaceDeform modifier tooltip.
Such place-holders should not pass final checks before merging in master!

355ad008a2 Surface Deform Modifier: Respect object transforms at bind time 
This slightly changes SDef behavior, by now respecting object transforms
at bind time, thus not requiring the objects to be aligned in their
respective local spaces, but instead using world space.

surface, thus allowing things such as cloth simulation proxies.
