Fix style in some header files.

* Enums must by typedef'd.
* Comments at end of `#define` must be `//` comments.
* Typedef structs must not be anonymous.
* `;` at the end of a `#define` is invalid.
* Callback typedefs must list their parameter names.
* No nested structs.
* No inline use of function pointer types. Only typedef'd callback types
  are allowed.
* Enum types are spelled in Camelsnake_Case.
* The argument to `#error` must be a string literal.
