The API now consists of the methods `new` and `next`.
The local checkpoint and SPK inventory are provided to
the constructor. `next` is now responsible for locating
the point of agreement.
The next filter to fetch is determined by the `next_block_hash`
field of `GetBlockHeaderResult`. If the next header has negative
confirmations due to a reorg, we rewind the internal state until
we find a header still in the best chain.
`Event` is changed to a simple struct containing `cp` and optional
`block`. The checkpoint is updated on each iteration whether
or not it corresponds to a matching block. We use
`CheckPoint::insert` which will also purge evicted blocks
if needed.
Change implementation of `find_base` to use `get_block_header_info`
which helps to reduce the number of RPC calls.
Removed `EventInner`.
Add test `event_checkpoint_connects_to_local_chain` to check
the expected events after a reorg, and check that intermediate
updates can be applied to the local chain.
