niftynei 0726d2912e df-mfc: remove guard-rails for failures
This will cause blow ups for v2 multifundchannel attempts with failures,
but allows us to return the expected errors for single-shot
fundchannel attempts.

Error handling is coming, i promise

niftynei b040a893ed mfc: avoid off-by-one rounding errors when finding change fee
Since we round down in `amount_tx_fee`, find the change fee as the
difference between what we've already paid and what the combined/total
fee would be if the change weight were also added.

niftynei 3793687550 mfc-df: if the psbt we've got has inputs from our peer, remove them
We only want to attempt to unreserve inputs that are ours (otherwise we

niftynei 6e3c517611 mfc-df: if there's an error with a openchannel_signed, fail
Ideally we'd 'cure' the error and re-attempt, except that if this was a
bitcoin-backend 'failure to broadcast' then it really needs user
intervention to figure out what's wrong -- it's possible that the
peer successfully broadcast the transaction

This avoids duplication of both logic and error-prone values, such as

allow us to fuzz it.

Antoine Poinsot 1513a2d07e hsmtool: input encryption password from stdin
This slightly breaks the API, but still accept the input: we just don't
take it into account anymore.

For `dumponchaindescriptors`, we have to still take the old place of the
`network` parameter into account to not entirely break the API.

Changelog-Added: hsmtool: password must now be entered on stdin. Password passed on the command line are discarded.

Christian Decker b3fd47e5f6 pytest: Stabilize test_routing_gossip
We were getting bad gossip because some nodes discarded the channel
announcement for being in the future. This is because the node was, at
that time, below the confirmation height. It'd then discard the
followup messages because not preceded by an announcement, and getting
upset about that.

Christian Decker 7e867e5ee6 pytest: Add throttler to limit load on the test system
Both my machine and apparently the CI tester machines regularly run
into issues with load on the system, causing timeouts (and
unresponsiveness). The throttler throttles the speed with which new
instances of c-lightning get started to avoid overloading. Since the
plugin used for parallelism when testing spawns multiple processes we
need to lock on the fs. Since we have that file open already, we'll
also write a couple of performance metics to it.
