Subject: Fix ogg123 speex stereo: Initialize stereo info data structure

The ogg123 executable wasn't able to correctly play stereo speex
files that don't contain any inband intensity stereo signals at
all or whose first inband intensity stereo signal arrives after
the stream has already started. This was due to the stereo
information data structure not being initialized properly before
the first inband intensity stereo signal arrived. So in the
mentioned cases the speex decoder used uninitialized float
values for the stereo decoding. This patch fixes the problem by
using the proper initialization and deallocation functions from
libspeex.
