assuming that all inputs would have a witness. While this was fine

Remove unnecessary borrow_parts() methods

Accessing a struct through an std::syn::MutexGuard using implicit
dereferencing can confuse the borrow checker. This situation arises when
obtaining mutable references to more than one field of the struct, which
is normally allowed.

https://doc.rust-lang.org/nomicon/borrow-splitting.html

However, when using implicit dereferencing, a mutable reference to the
the entire struct is taken. Thus, attempting to access another field in
this manner will lead to a compilation error.

https://doc.rust-lang.org/error-index.html#E0499

A simple way to avoid this is to first obtain a mutable reference to the
struct using explicit dereferencing.

Drop Result for ChannelMessageHandler methods

Simplify interfaces between ChannelMessageHandler and PeerManager,

internally instead of being return. With further refactors in Router
and PeerChannelEncryptor, errors management on the PeerManager-side
won't be splitted between try_potential_handleerror and HandleError
processing.

Inside ChannelManager, we now log MsgHandleErrInternal and send
ErrorAction to PeerManager.

On a high-level, it should allow client using API to be more flexible
by polling events instead of waiting function call returns.

We also update handle_error macro to take channel_state_lock from
caller which should avoid some deadlock potential for some edges
cases.
