Improve type safety of new logging system and its handling of varargs

- Replaced loglevel arguments and globals using the `int` type with the `loglevel` enum.
- Moved logging print func handler function declaration to typedef.
- Fixed misuse of `print_func` where a char* was passed in place of `va_list` via a wrapper function `print_funcf`.
- Fixed reuse of varargs in `logger` causing a segfault when `stderr_enabled` is true.
- Fixed length in `snprintf` call inside `logger_hex_dump` truncating the printed text.
