Allows for the removal of some BTreeMap usage when constructing NixAttrs
by allowing any iterator over 2-tuples to build a NixAttrs. Some
instances of BTreeMap didn't have anything to do with making NixAttrs,
and some were just the best tool for the job, so they are left using the
old `from_map` interface.

I primarily use GitHub for most of these preexisting repositories,
but they should be properly replicated on edwin in case I want to
stop. Pushing the respective refs manually is cumbersome and error
prone, so let's automate it.
The repositories are basically chowned to git:git currently and
`git fetch <remote> 'refs/*:refs/*' --prune` is execute regularly
to update the repository. In the future I could contemplate doing
it the other way round – using edwin as upstream and using
`git push --mirror` to update the GitHub repositories.

The backtrace-on-stack-overflow create provides best-effort stack
traces when a stack overflow happens. Since it's running on the
(usually tiny) signal alternate stack this isn't easy.
This is guarded by a new `backtrace_overflow` feature flag and never
enabled (even if that feature is selected) for release builds. This
is strictly for debugging; there's crazy unsafe voodoo in there.

This adds edwin, the machine running sterni.lv, as well as my
idiosyncratic deployment solution. It is based on instantiating the
system configuration locally (where you'd work on the configuration),
copying the derivation files to the remote machine where the system
derivation is realised and deployed. Unfortunately, the first step tends
to be quite slow (despite gzip compression), so this may not be the
definite way despite its advantages.

This adds the module I've been using for running my minecraft servers.
It is inspired by the declarative minecraft server module in nixpkgs,
but
* does not support a non-declarative mode.
* supports more than one server on the same machine.
* patches the fabric mod loader into the server.jar on startup.
* its stopping mechanism is more robust: It issues a `save-all` and
`stop` command over RCON and uses flock(1) for waiting on the
server's shutdown instead of relying on checking for the PID
via kill(1) in a loop.
It has some gaps in terms of features that I personally don't need, but
can be filled in over time.

This is an old project of mine, I have still deployed because a friend
was interested in using it (I think they never did though). The
repository can't be subtree-ed at the moment since it is AGPL and also
contains some personal information I would prefer not to check into such
a long-lived repository. Relicensing and subtree-ing it using a
semi-elaborate josh filter would be possible in the future, but I'm not
sure if it is worth it yet. This is probably good enough for now, the
project also very rarely breaks on channel updates.

For another project I need a way to fetch JS dependencies, as I couldn't
avoid them there. napalm seems to be the best option for this at the
moment, as the approach of running a local registry system seems to be
more robust than using npm's offline mode (which npmlock2nix) is doing.
If the latter gets better, it may be prudent to switch. napalm is
relatively unproblematic, i.e. no Haskell in IFD.
