Add a note that this may and probably will change over the lifetime of the
stream and should only be used as an initial hint.

Done.

nit: s/coded_size_/initial_frame_size_/ ? or just |frame_size_| ?

I noticed that the word 'size' is used a lot to denote the length of a buffer in
bytes and thus can be easily confused with geometrical size of a rectangle.

renamed to |initial_expected_coded_size_|, per dale's suggestion.  since it
comes from |coded_size| in the decoder config, i'd like to keep the name
similar.
