[development] Time to take away RTBC from every Joe

[Karoly Negyesi]

First of all, yes, I broke sometimes core by jumping the gun on RTBC.
But, I am aware of it. Now, let's see some other developer, quoted
from IRC after asking why RTBC'd a patch without any testing or
reviewing whatsoever (patch, of course, was absolutely broken and took
me hours to hunt down afterwards why stuff was broken and how it's
related to this one):

---
It means the idea of this patch is acceptable. I guess Dries
understands the risk before he commits this patch, and I am not the
only one to agree about its commit. so why just give me this credit
because I am the one who take RTBC action?
---

Onwards, I would like to see a small handful people (me not
necessarily included!) to be able to RTBC core patches. As we go on,
more and more people will misunderstand what this means. A nice
pyramid, a few people on top deciding the patches, a few more culling
the flood of patches for them. As there is already a permission for
this, a little hacking (which I am willing to do) surely would make it
possible to have it just for project 3060.

Kind regards,
