Package flags defines a set of constants to control support for certain features.
Other flags that may be added in the future may include:
PureGo: to control whether protobuf code should avoid using the unsafe
package and only use Go reflection.
PureProto: to control whether the proto package ignores the protoiface
package and only uses protobuf reflection. This is useful for testing.
Proto2ValidateUTF8: whether to validate UTF-8 in proto2 strings.
Proto3ValidateUTF8: whether to validate UTF-8 in proto3 strings.
