This replaces the previous Dockerfile, which was a single stage for
building and deployment.
The new one is a multi-stage build. Its "dev" target has the full
development environment; its "deploy" target is more slim. It supports
cross-compiled builds via BuildKit, eg to prepare a build suitable for
a Raspberry Pi:
docker buildx build --load --platform=linux/arm64/v8 --tag=moonfire-nvr --progress=plain --target=deploy -f docker/Dockerfile .
Coming next: updating the installation docs.
Both a "cargo update" and a bump of major versions of a few deps.
I left a few alone:
* base64 because some of the deps depend on 0.11 (and 0.9), so I don't
want to pull in a third version (0.12).
* ring because libpasta depends on this version and I don't want to pull
in two of them.
* time because it's not trivial. Last I checked, time 0.2 couldn't even
do what I wanted at all.
I also made tokio use parking_lot, since I pull it in anyway.
* As discussed in #48, say "The Moonfire NVR Authors" at the top of
every file rather than whoever created that file. Have one AUTHORS
file listing everyone.
* Consistently call it a "security camera network video recorder" rather
than "security camera digital video recorder".
