* remove validation package * structs cleanup * merge with apimiddleware removal * more validation and Bls capitalization * builder test fix * use strconv for uint->str conversions * use DecodeHexWithLength * use exact param names * rename http package to httputil * change conversions to fmt.Sprintf * handle query paramsd and route variables * spans and receiver name * split structs, move bytes helper * missing ok check * fix reference to indexed failure * errors fixup * add godoc to helper * fix BLS casing and chainhead ref * review * fix import in tests * gzl
