a45f4d3087 nostrdb/Query Plans 
Instead of running queries off filters directly, we do some simple
heuristics and determine a reasonable query plan for the given filter.

To test this, also add a kind index query plan and add a test for it.

We still need tag, author, and created_at index scans. This is up next!

8c5ec32eaa nostrdb/Initial nostrdb relay subscriptions 
This adds some initial code for the nostrdb relay subscription monitor.

When new notes are written to the database, they are checked against
active subscriptions. If any of the subscriptions are matched, the note
primary key is written to the inbox queue for that subscription.

We also add an ndb_wait_for_notes() method that simply waits for notes
to be written by the subscription monitor.

f2795aa71c nostrdb/blocks: add ndb_blocks_free 
In some situations we will need to have owned note blocks. For
example, when we try to fetch note blocks from the database and it's not
there yet. We will need to parse the content on the spot and return an
owned copy, since it will not be immediately available in the database.

Add a new flag field to note blocks that lets us know if it's owned by
malloc or nostrdb.

We the add a free function that checks this flag and frees the object if
its set. If it is not set then it doesn nothing because it likely came
from the database.
