The util module cotains some helper functions about string, string match, conversion,
path helpers.

int stringmatch(const char *p, const char *s, int nocase);
// convert strings like `10Gb`, `-128kb`, `30k` to int
long long memtoll(const char *p, int *err);
// counts digits in uint64
uint32_t digits10(uint64_t v);
