We cannot auto build amdadl-sdk on hydra, so setting license to unfree disable
auto builds. I also remove amdadl license, because it's irrelevant.
vcunat changed string license to attribute.
Nix-env always wants to install all outputs of a derivation, but this
failed for openjdk/openjre because openjdk has some symlinks (such as
bin/java) to openjre. Also, it prevents installing the openjre
without the openjdk. So as a workaround, mess with the "outputs"
attribute to fool nix-env.
Also, give openjre a separate name and description.
Fixes #1535.
E.g.
The unique option `fileSystems./.device' is defined multiple times, in `/etc/nixos/configuration.nix' and `/etc/nixos/foo.nix'.
This requires passing file/value tuples to the merge functions.
An annoying and dangerous property of "types.string" is that it merges
multiple definitions by concatenating them, which almost never
produces a sensible result. (Those options for which it does make
sense typically should use "types.lines" instead, and things only work
because the option definitions already end in a newline.) Of course,
you can use "types.uniq types.string", but that's rather verbose, and
inconsistent with other basic types like "types.int".
Changing the behaviour of "types.string" to be unique by default is
not an option, given the large number of options that use it. So
instead, we now have "types.str", which is equivalent to "types.uniq
types.string".
Now that overriding fileSystems in qemu-vm.nix works again, it's
important that the VM tests that add additional file systems use the
same override priority. Instead of using the same magic constant
everywhere, they can now use mkVMOverride.

For instance, if time.timeZone is defined multiple times, you now get
the error message:
error: user-thrown exception: The unique option `time.timeZone' is defined multiple times, in `/etc/nixos/configurations/misc/eelco/x11vnc.nix' and `/etc/nixos/configuration.nix'.
while previously you got:
error: user-thrown exception: Multiple definitions of string. Only one is allowed for this option.
and only an inspection of the stack trace gave a clue as to what
option caused the problem.
