some cleanup, store spent txs
...
pretty much everything is db based now. Still some concurrency issues
when multiple block inv messages come in (which they do) where
we used len(mBlockQueue) as a check for being synched up, which doesn't
quite work. Find a better way to do that...

fix dumb loop break error
...
break was outside the if bytes.Equal {}, oops. only checked first output.
Works now. Concurrency also seems OK but need to test more.

move tx ingest to all db, fixes sync
...
Sync was non-deterministic because ingest was concurrent.
Now receiving tx messages is blocking, but that's OK, they really need
to be in the right order because the whole point of bitcoin is to put
txs in the right order. SendTx still has a problem that the change address
may not be recognized by ingest.

mutex helps, still some sequence errors from mblocks
...
Seems that merkle blocks can return txs out of sequence, unlike
regular blocks which have to be in temporal/sequential order.
so maybe want to absorb ALL txs from mblock, then expel all?

fix more sync problems. Seems to work OK
...
One edge case is with long chains of unconfirmed txs.
All self-signed txs are stored, but not used to negate false incoming utxos yet.

not saying it works, but it works better
...
redo how db and header sync works, somewhat simpler but a little
recursve-ish. There is still an off by 1 error somewhere with headers.

new stxo struct and more db methods
...
I'm getting away from having both in-ram and on-disk stores for the transaction store data.
it should all be on disk, it's safer that way. It might be slower but this will not
process many txs / second anyway.

incoming invs and tx signing
...
when we get inv messages, txs are easy but blocks are a little tricky
block heigh synchronization is done via os' file system
signing is a bit inelegant (searches through inputs for pkscript matches)
but fast enough in practice

fix bolt slices. db read / write works.
...
also switch heights from uint32 to int32, which I guess is what they use.
Makes this thing last 2 billion blocks shorter. If we get past uint32 time.

oh right, another fun thing I forgot about
...
When there's only the coinbase tx, the merkle root = the coinbase txid.
Needless complication in bitcoin == job security?
