* Use debug builds in our Dockerfiles to reduce CI times
Also enables only spawning the mdns service when debug in the coordinator.
* Correct underflow in processor
Prior undetected due to relase builds not having bounds checks enabled.
* Restore Serai release due to CI/RPC failures caused by compiling it in debug mode
This is *probably* worth an issue filed upstream, if it can be tracked down.
* Correct failing debug asserts in Monero
These debug asserts assumed there was a change address to take the remainder.
If there's no change address, the remainder is shunted to the fee, causing the
fee to be distinct from the estimate.
We presumably need to modify monero-serai such that change: None isn't valid,
and users must use Change::Fingerprintable(None).
* De-duplicate Dockerfiles by using a bash file to concatenate common parts
Resolves#375.
Dockerfiles are still committed to the repo to avoid a dependency on bash.
* Add a CI job to confirm the committed dockerfiles are the currently generated ones
* Create dedicated Dockerfiles per processor network
Ensures the compromising of network-specific dependencies doesn't lead to a
compromise of the build process for all processors.
* Dockerfile corrections
* Correct call to build processor Docker image in tests/processor
