alsa-plugins: 1.0.29 -> 1.1.0

Changelog: http://alsa-project.org/main/index.php/Changes_v1.0.29_v1.1.0

The licensing of the libsamplerate plugin was relaxed a bit: if the
licensee has a commercial license for libsamplerate, the plugin can be
used under the terms of LGPL instead of GPL.

Both old patches are included in the new release, so dropped them.

Added a new patch to fix building against libspeexdsp 1.2rc3.
