More regularly send an Error message when we force-close a channel

channel on their end instead of trying to send through it and

Make `Channel`'s block connection API more electrum-friendly

Electrum clients primarily operate in a world where they query (and
subscribe to notifications for) transactions by script_pubkeys.
They may never learn very much about the actual blockchain and
orient their events around individual transactions, not the
blockchain.

This makes our ChannelManager interface somewhat more amenable to
such a client by splitting `block_connected` into
`transactions_confirmed` and `update_best_block`. The first handles
checking the funding transaction and storing its height/confirmation
block, whereas the second handles funding_locked and reorg logic.

Sadly, this interface is somewhat easy to misuse - notifying the
channel of the funding transaction being reorganized out of the
chain is complicated when the only notification received is that
a new block is connected at a given height. This will be addressed
in a future commit.

Switch to height-based funding-tx tracking from conf-based tracking

Previously, we expected every block to be connected in-order,
allowing us to track confirmations by simply incrementing a counter
for each new block connected. In anticipation of moving to a
update-height model in the next commit, this moves to tracking
confirmations by simply storing the height at which the funding
transaction was confirmed.

This commit also corrects our "funding was reorganized out of the
best chain" heuristic, instead of a flat 6 blocks, it uses half the
confirmation count required as the point at which we force-close.

Even still, for low confirmation counts (eg 1 block), an ill-timed
reorg may still cause spurious force-closes, though that behavior
is not new in this commit.

Correctly update the last block hash on disconnect

When a block is disconnected, the hash of the disconnected block was
used to update the last connected block. However, this amounts to a
no-op because these hashes should be equal. Successive disconnections
would update the hash but leave it one block off.

Normally, this not a problem because the last block_disconnected should
be followed by block_connected since the former is triggered by a chain
re-org. However, this assumes the user calls the API correctly and that
no failure occurs that would prevent block_connected from being called
(e.g., if fetching the connected block fails).

Instead, update the last block hash with the disconnected block's
previous block hash.
