Adds the two functions required in the backend to implement eth_getLogs, and adds some basic tests.

DO NOT MERGE before ava-labs/libevm#261 is finalized and merged

This error is in the filter API and not exported. Seems like a reasonable check, since I can't actually guarantee anything else without the blocking functionality

This whole file seems like it belongs in libevm, not here. Passing channels across API boundaries is a big code smell, suggesting incorrect abstraction/encapsulation.

Unfortunately, this is how it's implemented in libevm as well....

Well I moved it to libevm, so I guess if you don't like the boundaries still comment there. At least now, it's not expose to the API backend

Is there no way we can avoid this circular dependency?

We can, but it seemed unnecessarily complex. You need a quite a couple of the functions, so the only other options I know of are:

  1. Duplicate a bunch of logic in a second struct
  2. Embed a second struct inside the api backend and just pass that in

Is there a different option, or is one of these better?

Specifically, we need these methods:

type ChainIndexerChain interface {
	CurrentHeader() *types.Header
	SubscribeChainHeadEvent(ch chan<- ChainHeadEvent) event.Subscription
	OverrideHeaderBloom(header *types.Header) types.Bloom
}
