Wow, this is great. Is there a tool for this?

We also need a commit/PR removing unnecessary includes, as this PR has added some. For example, before this PR, bootstrap_daemon/src/command_line_arguments.c replied on getting #include "log.h" from bootstrap_daemon/src/command_line_arguments.h. But now that you have added #include "log.h" directly to bootstrap_daemon/src/command_line_arguments.c in this PR, the #include "log.h" in bootstrap_daemon/src/command_line_arguments.h is no longer needed.

[nurupo]

My bad, bootstrap_daemon/src/command_line_arguments.h actually needs #include "log.h". Edited my earlier comment.

It was completely manually, because clang-tidy --fix makes a huge mess. I took the error messages and manually added all the includes.

[nurupo]

How can I get these error messages from clang-tidy? Is there a specific check name I need to enable?

[nurupo]

Looks like this might be it https://clang.llvm.org/extra/clang-include-fixer.html

[iphydf]

It's --checks=-*,misc-include-cleaner.

static_assert(sizeof(int) >= 4, "toxcore does not support 16-bit platform");

Missing an s?

For clarity sake, SIGNATURE_SIZE used to be a size_t, making the cast necessary. Now it's an int so this change is okay.
