Deciding exactly where to draw the line for lite mode was hard -- different
users want different things.
There's two reasonable options here:

1) Read the entire istream to a string first, then call ParseFromString.
 Similarly, when writing, use SerializeToString() then write the entire
string to the ostream.

2) Go into the protobuf source and pull out
src/google/protobuf/io/zero_copy_stream_impl.*.  Find the classes for
reading from and writing to iostreams and copy them into your own project
code.  Then use ParseFromZeroCopyStream() and SerializeToZeroCopyStream()
with those classes.

Option (1) is simpler but (2) may be a little bit more efficient if your
messages are fairly large (probably around 100k or more).
