HTTP/3: fixed overflow in prefixed integer parser. Previously, the expression (ch & 0x7f) was promoted to a signed integer. Depending on the platform, the size of this integer could be less than 8 bytes, leading to overflow when handling the higher bits of the result. Also, sign bit of this integer could be replicated when adding to the 64-bit st->value.
