event log

[arvidn]

Purpose:

This patch adds support for enabling a binary event log for unfinished blocks, signage points and transactions.

This log is a "structured" log, i.e. it's a stream of messages in a network-protocol-like format, streamed into a file (rotated every 100 MB).

Currently the following events are logged:

1. new peers (this is required to record information about the peers sending the other messages)
2. Incoming UnfinishedBlocks
3. Outgoing UnfinishedBlocks
4. Incoming signage point
5. incoming transaction (for the mempool)
6. NewPeak

The intention is that this format can be extended with additional events in the future.

This patch does not include any tools for analyzing or parsing the resulting log. Those tools will be submitted in a separate PR.
