watchtower/wtdb: only accept properly sized blobs 
Modifies the bbolt and mock tower databases to only accept blobs that
are the expected size of the session's blob type. This prevents resource
exhaustion attacks where a client may provide disproportionately large
encrypted blob, even though all supported blob types are of fixed-size.

watchtower/wtwire/message: bump wtwire messages outside reserved ranges 
BOLT01 reserves the following ranges:
 - Setup & Control (types 0-31)
 - Channel (types 32-127)
 - Commitment (types 128-255)
 - Routing (types 256-511)

The wtwire messages now occupy 600-607.

watchtower/wtclient/client: use existing session with same TxPolicy 
This commit modifies the client's filtering when selecting from existing
sessions. The new logic compares the configured TxPolicy with the
TxPolicy of the candidate sessions, which has the effect of ignoring
operational parameters such as MaxUpdates. Prior, changing MaxUpdates
would cause the client to request a new session even if it had perfectly
good slots available in a policy with an equal TxPolicy.

watchtower/multi: embed TxPolicy in wtpolicy.Policy 
This commit splits out the parameters that shape the justice transaction
into their own struct, which then embedded within the overarching
wtpolicy.Policy which may have additional parameters describing
operation of the session.

This is done as a preliminary step to support comparison of sessions
based on matching TxPolicy configurations. This prevents otherwise
identical Policies from being counted as different if operational
parameters like MaxUpdates differ, even if it has no material difference
to the justice transaction.

watchtower/wtclient/client: avoid over requesting sessions 
This commit fixes a bug that would cause us to request more sessions
that needed from the session negotiator. With the current stat ticker,
we'd ask the negotiator for a new session every 30s if session
session negotiation did not return before printing the stats. Now we'll
avoid requesting to sessions by jumping back into the select loop.

watchtower/wtdb: add CSessionStatus field to ClientSession 
This commit adds persisted status bit-field to ClientSessions, that can
be used to modify behavior of their handling in the client. Currently,
only a default CSessionActive status is defined. However, the intention
is that this could later be used to signal that a session is abandoned
without needing to perform a db migration to add the field. As we move
forward with testing, this will likely be useful if a session gets
borked and we need a simple method of the client to temporarily ignore
certain sessions.

The field may be useful in signaling other types of status changes,
though this was the primary motivation that warranted the addition.

watchtower/wtclient: dedup backups across restarts

watchtower/wtclient: integrate ClientChannelSummaries 
In this commit, we utilize the more generic ClientChanSummary instead of

watchtower/wtdb/client_chan_summary: add ClientChanSummary 
A ClientChanSummary will be inserted for each channel registered with
the client, which for now will just track the sweep pkscript to use. In
the future, this will be extended with additional information to enable
the client to efficiently compute which historical states need to be
backed up under a given policy.

watchtower/wtdb: create embedded ClientSessionBody

watchtower/wtdb: return sorted ClientSession.CommittedUpdates 
This commit replaces the map-based CommittedUpdates field with a slice.
When reading from disk, these will already be sorted by bbolt, so the
client restore the updates as presented without needing to sort them
first.

Since the key in the map variant was the sequence number, we refactor
the CommittedUpdate struct to have a sequence number and an embedded
CommittedUpdateBody (which is equivalent to the old CommittedUpdate).
The database is then expected to populate the sequence number from the
key on disk.

Since the sequence number is now directly integrated in the
CommittedUpdate struct, this allow allows us to remove the now redundant
seqNum argument from CommitUpdate.

watchtower/wtdb: prepare for addition of client db 
This commit renames the variables dbName to towerDBName and dbVersions
to towerDBVersions, to distinguish between the upcoming clientDBName
clientDBVersions. We also move resusable portions of the database
initialization and default endianness to its own file so that it can be
shared between both tower and client databases.

multi: remove ErrDoubleSpend check for PublishTransaction 
In this commit, we address a lingering issue within some subsystems that
are responsible for broadcasting transactions. Previously,
ErrDoubleSpend indicated that a transaction was already included in the
mempool/chain. This error was then modified to actually be returned for
conflicting transactions, but its callers were not modified accordingly.
This would lead to conflicting transactions to be interpreted as valid,
when they shouldn't be.

watchtower/wtclient/backup_task: make sweep pkscript independent of session 
This commit changes when the sweep pkscript
is assigned in the construction of the justice
transaction. Currently, the sweep pkscript is
assigned when the task is bound to a session.
However, we will moving to an assignment where
a unique sweep pkscript is used per channel to
prevent address inflation. Hence, this commit
makes the sweep pkscript a state dependent
variable, since it can be known at the time the
channel id is assigned.

watchtower/blob/type: introduces blob type flags 
Adds flags for reward outputs and commitment outputs.
The fixed-size encoding for commitment outputs is
treated as a flag, so that the blob format can be
modified, extended, or replaced in future iterations.

watchtower/blob/justice_kit_test: remove external nonce

watchtower/blob/justice_kit: use randomized 192-bit nonce 
This commit modifies the blob encryption scheme to
use chacha20-poly1305 with a randomized 192-bit nonce.
The previous approach used a deterministic nonce scheme,
which is being replaced to simplify the requirements of
a correct implementation.  As a result, each payload
gains an addtional 24-bytes prepended to the ciphertext.

watchtower/blob/justice_kit: return DER signatures 
This commit fixes an issue with the witness stack
construction for to-local and to-remote inputs,
that would cause the justice kit to return
signatures as fixed-size, 64-byte signatures.
The correct behavior is to return DER-encoded
signatures so that they will properly verify on
the network, since the consensus rules won't
be able to understand the fixed-size variant.

watchtower/blob/justice_kit: add variable length sweep addr 
This commit fixes an oversight in the previous
design of the watchtower blob, by introducing
a length byte for sweep addresses. The previous
format supposed that addresses would be padded
to 42 bytes, but had no indication of the
address's actual length.

To rememdy this, we introduce a single byte
indicating the actual size of the address,
such that the padding can be removed upon
decoding.
