The ability to stfu channels in bulk is required to do complex multi channel operations. When stfu’ing in this manner, the available funds at the moment of stfu is returned to the user.
In order to cancel the stfu we also add a bulk tx_abort command.
Changelog-Added: `stfu_channels` and `abort_channels` are added for bulk multi-channel splice commands. These allow the user to pause (and resume) multiple channels in place.
I started getting "WIRE_TEMPORARY_CHANNEL_FAILURE: Too many HTLCs" after
two hundred xpay attempts.
This was nice (it found some bugs in injectpaymentonion's handling of
local errors, and in xpay's reporting), but shouldn't happen.

Start with a random capacity (linear prob), and remember in-progess
payments so we can simulate them using capacity properly.

Note the impedence mismatch between sendpay and getroutes: we have to shift
amounts and delays by 1.

Our gossmap_store uncompresser generates nodeids with well-known
privkeys, so we can decrypt and respond to HTLCs sent to such nodes.
By replacing channeld with a fake, we can connect a node to another
node, but then once the channel is established, allow payments to be
sent into the generated network, and respond appropriately.
This minimal version handles MPP timeouts, but doesn't insert any
delays or runtime capacity for channels.
