This isn't quite a 100% clean sweep of IWYU.
There are some false positives where clang fails.
Additionally there are still a few missed in the frontend side of things
that I didn't get to
Addresses #146 a little more by providing an interface to perform
fmt-compatible logging.
No more, will people on the project be tormented by classic printf
features like:
- Accidentally passing in a non-trivial type
- PRI macros
- Not being able to add support for custom types
- Mixing up signed/unsigned printf formatting specifiers accidentally
fmt-capable versions of the logging functions are named the same as the
existing functions, just with a "Fmt" or _FMT suffix (depending on
whether or not it's a function being used or a macro, respectively).
va_list types have an edge where after operating on it, then it is undefined behaviour to do anything other than va_end on the object.
So in order to call vsnprintf on it multiple times we must create copies with va_copy.
Easy enough to work around by doing a few more copies of the va_list
