The fn.WriteFile writes data like os.WriteFile but in sync mode.
Also adds a behaviour flag that enables removal of file on error.

When notifying the invoice registry for an exit hop htlc we also want to
include its custom records. The channelLink, the other caller of this
method, already populates this field. So we make sure the contest
resolver does so too.
In a rare case when the critical log is triggered when using postgres as
db backend, the `payment` could be nil cause the server is shutting
down, causing the payment fetching to return an error. We now cache its
state before fetching it from the db.
We have two sources which can call `handlePacketSettle`, either through
the link's `<-s.htlcPlex`, or the `<-s.resolutionMsgs`, which means the
`closeCircuit` could be call twice. Previously we already caught this
case inside `closeCircuit`, in that we would return a nil circuit upon
seeing `ErrUnknownCircuit`, indicating the circuit was removed. However,
we still need to account the case when the circuit is the process of
being closed, which is now fixed as we will ignore when seeing
`ErrCircuitClosing`.
In this commit, the ContextGuard struct is re-worked such that the
context that its new main WithCtx method provides is cancelled in sync
with a parent context being cancelled or with it's quit channel being
cancelled. Tests are added to assert the behaviour. In order for the
close of the quit channel to be consistent with the cancelling of the
derived context, the quit channel _must_ be contained internal to the
ContextGuard so that callers are only able to close the channel via the
exposed Quit method which will then take care to first cancel any
derived context that depend on the quit channel before returning.
To make this itest work reliably with multiple parallel SQL
transactions, we need to count both the settle and final HTLC
events. Otherwise, sometimes the final events from earlier
forwards are counted before the forward events from later
forwards, causing a miscount of the settle events. If we
expect both the settle and final event for each forward,
we don't miscount.
This is a tradeoff of disk space (and with that cache size) and
compilation speed. Because we're still running into disk full errors
with the full build cache, we remove it for the cross compile step.
Which means we'll do more work each time.
In this commit, we enable a custom payer for the rbf coop close. This
allows us to ensure that the party that started one side of the close
flow pays the fees.
In this commit, we update the core coop close logic with the new custom
payer param. We also expand the existing unit tests to ensure that the
fee is deducted from the proper party.
This preps us for an upcoming change to the rbf coop state machine where
either party can pay for the channel fees. We also add a new test to
make sure the new function adheres to some key properties.
