Message.Builderother into the message being built. other must

Merging occurs as follows. For each field:other,
then other's value overwrites the value in this message.other,
it is merged into the corresponding sub-message of this message
using the same merging rules.other are concatenated
with the elements in this message.

repeated int32 path = 1 [packed = true];
Identifies which part of the FileDescriptorProto was defined at this
location.
Each element is a field number or an index. They form a path from
the root FileDescriptorProto to the place where the definition. For
example, this path:
[ 4, 3, 2, 7, 1 ]
refers to:
file.message_type(3) // 4, 3
.field(7) // 2, 7
.name() // 1
This is because FileDescriptorProto.message_type has field number 4:
repeated DescriptorProto message_type = 4;
and DescriptorProto.field has field number 2:
repeated FieldDescriptorProto field = 2;
and FieldDescriptorProto.name has field number 1:
optional string name = 1;
Thus, the above path gives the location of a field name. If we removed
the last element:
[ 4, 3, 2, 7 ]
this path refers to the whole field declaration (from the beginning
of the label to the terminating semicolon).
