Lots of code was using 32-byte nonces for xchacha20 symmetric
encryption, but this just means 8 extra bytes per packet wasted as
chacha is only using the first 24 bytes of that nonce anyway.
Changing this resulted in a lot of dead/dying code breaking, so this
commit also removes a lot of that (and comments a couple places with
TODO instead)
Also nounce -> nonce where it came up.
- RemoteRC supplants most of the functionality throughout the code of RouterContact
- Next step will be to sort out CI issues, then see if we can get rid of either LocalRC (and therefore RouterContact entirely)
- includes are now sorted in consistent, logical order; first step in an attempt to fix the tomfoolery (no relation to Tom) brought in by include-what-you-use
- shuffled around some cmake linking to simplify dependency graph
- superfluous files removed
All #ifndef guards on headers have been removed, I think,
in favor of #pragma once
Headers are now included as `#include "filename"` if the included file
resides in the same directory as the file including it, or any
subdirectory therein. Otherwise they are included as
`#include <project/top/dir/relative/path/filename>`
The above does not include system/os headers.
This commit reflects changes to clang-format rules. Unfortunately,
these rule changes create a massive change to the codebase, which
causes an apparent rewrite of git history.
