Adam Joseph c91d86ee5c feat(tvix/eval): NixList::concat(): avoid an unnecessary move 
In `a++b`, the previous implementation would move `b` (i.e. memcpy
its elements) twice.  Let's do that only once.

We sure do call NixList.clone() a whole lot.  At some point in the
future we probably want to do a SmolStr-type split for NixList into
a two-variant enum where one side is an Rc<Vec<Value>> for lists
longer than a certain length.

License structure

All code implemented for Tvix is licensed under the GPL-3.0, with the exception of the protocol buffer definitions used for communication between services which are available under a more permissive license (MIT).

The idea behind this structure is that any direct usage of our code (e.g. linking to it, embedding the evaluator, etc.) will fall under the terms of the GPL3, but users are free to implement their own components speaking these protocols under the terms of the MIT license.
