* newRequestID() (previously generateUploadID()) returns string than byte array. * Remove unclear comments and added appropriate comments. * SHA-256, MD5 Hash functions return Hex/Base64 encoded string than byte array. * Remove duplicate MD5 hasher functions. * Rename listObjectsValidateArgs() into validateListObjectsArgs() * Remove repeated auth check code in all bucket request handlers. * Remove abbreviated names in bucket-metadata * Avoid nested if in bucketPolicyMatchStatement() * Use ioutil.ReadFile() instead of os.Open() and ioutil.ReadAll() * Set crossDomainXML as constant.
