scripts/functions: add aria2, a powerfull downloader

aria2 is a powerfull downloader that is capable of chunking and
parallel retrieval.

Due to li;itations in crosstool-NG retrieval facilities, it's not possible
to take fully advantage of aria2. It might happen that, in the future,
those limitations get lifted away, so we can take use features such as
parallel downloading from more than one server at the same time. For now,
it should still speed up downloads thanks to parallel downloading of chunks.

     7 textrels are bad for forcing copy-on-write (this affects everyone),

     8 and for security/runtime code generation, this affects security ppl.

     9 But in either case, it doesn't matter who needs textrels, it's

    10 the very fact that they're needed at all.
