[GSoC] 'Independency of D from the C Standard Library' progress and update thread

[Stefanos Baziotis]

As it is mentioned in a previous post, this project has got 
hardly any attention. And since there was nothing to do, I did 
not post weekly.

=== Current State ===

--- Dmem* utilities ---

Fortunately, Nicholas Wilson has been helping me the last week 
get the 2 Dmem*
PRs I had done merged [1], [2]

I don't know of anything that these PRs need, although possibly I 
have done something wrong in the documentation.

I don't know if / when they will get merged since they're 
awaiting review.
I hope to have enough reviews to merge at least memset in the 
next 2.5 weeks.
And again, thanks a lot Nicholas for your time.

--- core.thread ---

Since there was nothing to do, I asked if there was anything that 
I could
do in the time. It was proposed that I could refactor core.thread.
With some help from Nicholas, I made a PR [3].
I'm glad that people seem to care about this change. It's going 
good I think.

=== Final 2.5 weeks ===

I honestly have no idea. Ideally, I would PR memmove() as well 
but I think it's
better to try to get at least one of the other 2 PRs merged first.
Other than that, if the core.thread gets merged, I will finish it.

One thing I proposed for the time remaining is a cross-compiler 
SIMD module.
I will write in a separate thread about that, but the idea came 
from the fact that when writing Dmem* utils, I could not find a 
way to use SIMD intrinsics
across compilers. So, I created something like a small SIMD 
library [4].
That is of course not really general, but it shows the idea.
