This patch implements `hcreate(_r)/hsearch(_r)/hdestroy(_r)` as specified in https://man7.org/linux/man-pages/man3/hsearch.3.html. Notice that `neon/asimd` extension is not yet added in this patch. - The implementation is largely simplified from rust's [`hashbrown`](https://github.com/rust-lang/hashbrown/blob/master/src/raw/mod.rs) as we only consider fix-sized insertion-only hashtables. Technical details are provided in code comments. - This patch also contains a portable string hash function, which is derived from [`aHash`](https://github.com/tkaitchuck/aHash)'s fallback routine. Not using any SIMD acceleration, it has a good enough quality (passing all SMHasher tests) and is not too bad in speed. - Some general functionalities are added, such as `memory_size`, `offset_to`(alignment), `next_power_of_two`, `is_power_of_two`. `ctz/clz` are extended to support shorter integers.
