Yes, you are right that Ogg packets are always a whole number of bytes
in length.

The bitpacking routines in libogg are completely separate from the
framing (the part which handles page and packet headers, and thus
packet lengths etc.) That bitpacker is only used by the Vorbis codec,
it's not really a part of Ogg encapsulation.
