The "size" member was confusing - it's the size of the allocation, not the size of the current string. The size of the current string is the member called "used". This naming makes perfect sense for the internal implementation, but it's confusing to users who actually do want to get the size of the resulting string at the end. So rename the fields to "alloc" and "len" - which is pretty clear. This also adds a helper function to strip whitespace from the end: "strip_mb()".
