[bindings] Use resolved, not local ident in generic mangling
In traits with associated types which are returned in generics (ie
`trait T { type A: B; fn c() -> Result<Self::A, ()> {} }`), we
created a new generic mapping with the local type name (in this
case A) instead of using the real type (in this case B). This is
confusing as it results in generic manglings that don't reference
the real type (eg `LDKCResult_ChanKeySignerDecodeErrorZ`) and
may have multiple generic definitions that are identical.
Instead, we now use the final ident in the resolved mapping. The
biggest win is `LDKCResult_ChanKeySignerDecodeErrorZ` changing to
`CResult_ChannelKeysDecodeErrorZ`. However, there are several types
where `secp256k1::Error` was imported as `SecpError` and types like
`LDKCResult_SecretKeySecpErrorZ` are now
`LDKCResult_SecretKeyErrorZ` instead. Still, the type of the error
field remains `LDKSecp256k1Error`, which should avoid any confusion.

Panic if signing fails in OnChainTx
Signatures in OnChainTx must not fail, or we stand to lose funds

Fold sign_holder_commitment_htlc_transactions into sign_holder_commitment
Signing the commitment transaction is almost always followed by signing the attached HTLC transactions, so fold the signing operations into a single method.

Use `KeysInterface::read_chan_signer` for all channel keys deser
This drops any direct calls to a generic `ChannelKeys::read()` and
replaces it with the new `KeysInterface::read_chan_signer()`. Still,
under the hood all of our own `KeysInterface::read_chan_signer()`
implementations simply call out to a `Readable::read()` implemention.

Add a new method `read_chan_signer` to `KeysInterface`
This adds a new method to the general cross-channel `KeysInterface`
which requires it to handle the deserialization of per-channel
signer objects. This allows the deserialization of per-channel
signers to have more context available, which, in the case of the
C bindings, includes the actual KeysInterface information itself.

Use Writeable for ChannelMonitor instead of a specific function.
There's no reason to have ChannelMonitor::write_for_disk instead of
just using the Writeable trait anymore. Previously, it was used to
differentiate with `write_for_watchtower`, but support for
watchtower-mode ChannelMonitors was never completed and the partial
bits were removed long ago.
This has the nice benefit of hitting the custom Writeable codepaths
in C bindings instead of trying to hit trait-generics paths.
Matt Corallo [Wed, 25 Nov 2020 17:23:37 +0000 (12:23 -0500)]
Universally Require Writeable for ChannelKeys
It doesn't make sense to ever build a lightning node which doesn't
ever write ChannelMonitors to disk, so having a ChannelKeys object
which doesn't implement Writeable is nonsense.
Here we require Writeable for all ChannelKeys objects, simplifying
code generation for C bindings somewhat.

Cache fields instead of storing a ChannelKeys in ChannelMonitor
We only actually use two of the fields in ChannelKeys inside a
ChannelMonitor - the holder revocation_basepoint and the
derivation parameters. Both are relatively small, so there isn't
a lot of reason to hold a full copy of the ChannelKeys (with most
of the interaction with it being inside the OnchainTxHandler).
Further, this will avoid calling read on a `ChannelKeys` twice,
which is a somewhat strange API quirk.
