When using MariaDB v10.5+ Foreign-Key errors were popping up because of
some changes in that version. To mitigate this on MariaDB and other
MySQL forks those errors are now catched, and instead of a replace_into
an update will happen. I have tested this as thorough as possible with
MariaDB 10.5, 10.4, 10.3 and the default MySQL on Ubuntu Focal. And
tested it again using sqlite, all seems to be ok on all tables.

Diesel requires the following changes:
- Separate connection and pool types per connection, the generate_connections! macro generates an enum with a variant per db type
- Separate migrations and schemas, these were always imported as one type depending on db feature, now they are all imported under different module names
- Separate model objects per connection, the db_object! macro generates one object for each connection with the diesel macros, a generic object, and methods to convert between the connection-specific and the generic ones
- Separate connection queries, the db_run! macro allows writing only one that gets compiled for all databases or multiple ones
This includes migrations as well as Dockerfile's for amd64.
The biggest change is that replace_into isn't supported by Diesel for the
PostgreSQL backend, instead requiring the use of on_conflict. This
unfortunately requires a branch for save() on all of the models currently
using replace_into.
For now only folder notifications are sent (create, rename, delete).
The notifications are only tested between two web-vault sessions in different browsers, mobile apps and browser extensions are untested.
The websocket server is exposed in port 3012, while the rocket server is exposed in another port (8000 by default). To make notifications work, both should be accessible in the same port, which requires a reverse proxy.
My testing is done with Caddy server, and the following config:
```
localhost {
# The negotiation endpoint is also proxied to Rocket
proxy /notifications/hub/negotiate 0.0.0.0:8000 {
transparent
}
# Notifications redirected to the websockets server
proxy /notifications/hub 0.0.0.0:3012 {
websocket
}
# Proxy the Root directory to Rocket
proxy / 0.0.0.0:8000 {
transparent
}
}
```
This exposes the service in port 2015.
