static inline int get_uint_option(const char *name, const unsigned int fallback)
option.h: Introduce {get,set}_int_option() functions The {get,set}_option() functions are not type-safe: they take a pointer to void, without an associated length/size. Moreover, cmos_get_option() does not always fully initialise the destination value (it has no means to know how large it is), which can cause issues if the caller does not initialise the value beforehand. The idea behind this patch series is to replace the current type-unsafe API with a type-safe equivalent, and ultimately decouple the option API from CMOS. This would allow using different storage mechanisms with the same option system, maximising flexibility. Most, if not all users of get_option() have a value to fall back to, in case the option could not be read. Thus, get_int_option() takes a value to fall back to, which avoids repeating the same logic on call-sites. These new functions will be put to use in subsequent commits.
