resolve stricter warnings
In order to convert this repository to Meson, we need to make it
compile under `warning_level=3`. Fix a number of warning classes
across the repository or disable them.
Some fixes are:
* Add missing header files.
* Fully initialize structs as necessary.
* Add `__attribute__((unused))` on parameters as necessary.
* Fix comparisons between signed and unsigned.
* Fix printf specifiers as necessary.
* Avoid case-fallthrough.
* Remove if conditions which are always true.
Some warnings would require extensive code changes, due to their
pervasive use, and so are disabled at a per-file level:
* `-Wpointer-arith`
* `-Wunused-result`
