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.

     3 # Here, we can update the config.* scripts.
     4 # If we're in CT_LIB_DIR, then CT_LIB_DIR == CT_TOP_DIR, and we can update those
     5 # scripts for later inclusion mainline. If CT_LIB_DIR != CT_TOP_DIR, then those
     6 # scripts are downloaded only for use in CT_TOP_DIR.
