5a91419d34 feat(NIP-20): send command results to clients 
When submitting events to relays, clients currently have no way to know
if an event was successfully committed to the database. This NIP
introduces the concept of command results which are like NOTICE's except
provide more information about if an event was accepted or rejected.

A command result is a JSON object with the following structure that is
returned when an event is successfully saved to the database or
rejected:

	["OK", <event_id>, <true|false>, <message>]

relay is behind cloudflare, so to get accurate remote ip logging we need

311f4b5283 refactor: switch new connections to debug log 
These are pretty spammy on busy relays. I've been using the info log to
monitor spam attacks, and these are the least useful info log.

Leave the "stopping connection" log because it at least provides useful
sent/received information.

72f8a1aa5c feat(NIP-26): allow searches for delegated public keys 
Implements core NIP-26 delegated event functionality.  Events can
include a `delegation` tag that provides a signature and restrictions
on which events can be delegated.

Notable points on the implementation so far:

* Schema has been upgraded to include an index and new column.
* Basic rune parsing/evaluation to implement the example event in the
  NIP, but no more.
* No special logic for deletion.
* No migration logic for determining delegated authors for
  already-stored events.

Previously there was an error which search results from being returned

just choose any or the last limit seen.

2d28a95ff7 feat: allow arbitrary tag queries 
This is an experimental feature, outside of any NIP, that demonstrates
generic tag queries.

Instead of limiting subscription filters to just querying only "e" or
"p" tags (via `#e` or `#p` attributes), any tag can be queried.

As an example, consider an event which uses a tag "url".  With this
modification, a subscription filter could add a top-level field
"#url", with an array of strings as the key.  Exact matches would be
returned.

A NIP is forthcoming to formalize this.

refactor: add strictly typed tags 
* Add custom error variant

This can be useful to propagate errors not conforming to available
variants. Also to convert other errors in `crate::Error` without having
explicit conversion defined, with `error.to_string()`

* Implement `Tag` and define protocol serialization

A Tag structure have been implemented with dedicated field types. Then
custom serde serialization is derived to map the structure to current
protocol json array as per NIP01.

This adds compile and run time type checking to always ensure wrong
string data are never stored or processed. With strict typed fields and
custom serde derivation this checks can be done at time of serialization,
saving work for internal handling of the actual data.

tests for possible data violations are added, and gives good example of
kind of errors it will through for different cases.

* Use String for URL

1589268eba fix: use database to publish all events 
This fixes a race condition where a publisher might send an event, and
immediately after issue a subscription for the same event ID.  Prior
to this change, that event would have been published on the broadcast
channel (and ignored by our publisher, because they had not yet issued
the subscription), but not yet committed to the database.  Their
subscription would trigger a database query which would return zero
results.  Therefore, they would never see the event they published.
The noscl tool is one client that would suffer from this.

Now, all events are broadcast only after they exist in the database,
so a late subscription will always return the event.
