Implement struct wrappers for channel key types to avoid confusion.
Currently all channel keys and their basepoints exist uniformly as
`PublicKey` type, which not only makes in harder for a developer to
distinguish those entities, but also does not engage the language
type system to check if the correct key is being used in any
particular function.
Having struct wrappers around keys also enables more nuanced
semantics allowing to express Lightning Protocol rules in language.
For example, the code allows to derive `HtlcKey` from
`HtlcBasepoint` and not from `PaymentBasepoint`.
This change is transparent for channel monitors that will use the
internal public key of a wrapper.
Payment, DelayedPayment, HTLC and Revocation basepoints and their
derived keys are now wrapped into a specific struct that make it
distinguishable for the Rust type system. Functions that require a
specific key or basepoint should not use generic Public Key, but
require a specific key wrapper struct to engage Rust type
verification system and make it more clear for developers which
key is used.

`derive(Hash)` for P2P messages
In other languages (Java and C#, notably), overriding `Eq` without
overriding `Hash` can lead to surprising or broken behavior. Even
in Rust, its usually the case that you actually want both. Here we
add missing `Hash` derivations for P2P messages, to at least
address the first pile of warnings the C# compiler dumps.

Rely on const generic big arrays for `PartialEq` in msgs
Implementation of standard traits on arrays longer than 32 elements
was shipped in rustc 1.47, which is below our MSRV of 1.48 and we
can use to remove some unnecessary manual implementation of
`PartialEq` on `OnionPacket`.
