234a8ba0ac feat: limit event publishing to NIP-05 verified users
This adds a new configurable feature to restrict event publishing to
only users with NIP-05 verified metadata.  Domains can be whitelisted
or blacklisted.  Verification expiration and schedules are
configurable.

This upgrades the database to add a table for tracking verification
records.

4cc313fa2d fix: cleanup database connections with same name
When a large number of subscriptions is created with identical names,
we do not send a signal over the abandon-read channel.  This
eventually leads to resource exhaustion.

This adds a configuration option, `authorization.pubkey_whitelist`
which is an array of pubkeys that are allowed to publish events on
this relay.

2924da88bc feat: incorporated improvements from NIP-11 discussion
Change descr to description.  Add `id` for websocket URL.  Use
integers for supported NIPs instead of strings.  Top-level is object,
instead of the array before.

1aa5a5458d improvement: event signature validation is 100x faster
Switched to latest (git) release of secp256k1, which has more
efficient verification-only context for Schnorr.  Switched to single
pre-instantiated instance of the verifier.

620e227699 fix: connection issues with Firefox
This adds Hyper, and a 200 response code.  Prior to this, Firefox
would fail to connect.  There is also a text document displayed at the
root URL to indicate this is a Nostr relay.

49598b2c9e fix: subscription event filtering bugs
Subscriptions properly filter using the authors tag.  Petname/keys are
correctly filtered (previously the event tags were incorrectly used).

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.
