Log Message:
Update to speex-1.2rc1.  This should be backward-compatible with
1.0.x versions.  Pulseaudio (which I am working on) requires
this version; moreover, the 1.0.x releases are deprecated.

The ChangeLog is not kept up-to-date, but here are some highlights:

1.2rc1
--------
Again, this new releases brings many improvements. The RAM requirement for
wideband has gone down drastically (i.e. more than 2x). A new resampler
module has been added, providing arbitrary sampling rate conversion --
fast. The echo canceller has also been improved. A bug in 1.2beta1 that
made the echo canceller unstable has been fixed. The echo canceller should
now converge faster, be robust and tolerant of incorrect capture-playback
synchronisation. The preprocessor has also been greatly improved. Not only
should the quality be better, but it is now fully converted to
fixed-point. At last, early TriMedia support (incomplete) has been merged.

1.2beta3
--------
The most obvious change in this release is that all the non-codec
components (preprocessor, echo cancellation, jitter buffer) have been
moved to a new libspeexdsp library. Other changes include a new jitter
buffer algorithm and resampler improvements/fixes. This is also the first
release where libspeex can be built without any floating point support. To
do this, the float compatibility API must be disabled (--disable-float-api
or DISABLE_FLOAT_API) and the VBR feature must be disabled (--disable-vbr
or DISABLE_VBR).

1.2beta2
--------
This release adds support for acoustic echo cancellation with multiple
microphones and multiple loudspeakers. It also adds an API to decorrelate
loudspeaker signals to improve multi-channel performance. In the bugfix
department, there are fixes for a few bugs in the echo canceller, jitter
buffer and preprocessor. At this point, the API for 1.2 should be stable
and only a few very minor additions are planned.
