Do not test any block-contents-rescan cases

In anticipation for removing support for users calling
block_connected multiple times for the same block to include all
relevant transactions in the next PR, this commit stops testing
such cases. Specifically, users who filter blocks for relevant
transactions before calling block_connected will need to filter by
including any transactions which spend a previously-matched
transaction in the same block (and we now do so in our own
filtering logic, which is also used in our testing).

   states we "MUST set htlc_minimum_msat to the minimum HTLC value
   (in millisatoshi) that the channel peer will accept." This makes
   sense because the reason we're rejecting the HTLC is because our
   counterparty's HTLC minimum value is too small for us to send to
   them, our own HTLC minimum value plays no role. Further, our
   router already expects this - looking at the same directional

In order to calculate a route, it is likely that users need to take
a read()-lock on NetGraphMsgHandler::network_graph. This is not
possible naively from C bindings, as Rust's native RwLock is not

Rename TxCreationKeys::new to not conflict w/ auto-gen'd C bindings

Give ChannelManagerReadArgs HashMap-of-monitors ownership

Its somewhat awkward that ChannelManagerReadArgs requires a mutable
reference to a HashMap of ChannelMonitors, forcing the callsite to
define a scope for the HashMap which they almost certainly won't use
after deserializing the ChannelManager. Worse, to map the current
version to C bindings, we'd need to also create a HashMap binding,
which is overkill for just this one use.

Instead, we just give the ReadArgs struct ownership of the HashMap
and add a constructor which fills the HashMap for you.

Use ln OutPoints not bitcoin ones in SpendableOutputDescriptors

Lightning OutPoints only have 16 bits to express the output index
instead of Bitcoin's 32 bits, implying that some outputs are
possibly not expressible as lightning OutPoints. However, such
OutPoints can never be hit within the lightning protocol, and must
be on-chain spam sent by a third party wishing to donate us money.
Still, in order to do so, the third party would need to fill nearly
an entire block with garbage, so this case should be relatively
safe.

A new comment in channelmonitor explains the reasoning a bit
further.
