add new Factory object in java, so that filter enablement can be controlled with the new way of doing it.

opensles should be used at preferred sample rate, which workaround latency problems.

Use Java soundcard only to record on Android and use OpenSLES soundcard only to play audio if there is an HAEC

improve it for android too.

On request of changing speaker phone state the sound_read filter is post_processed,
speaker state is changed by calling back java application through jni,
then sound_read filter is pre_processed.

By doing this, the speaker state changes effectively and the microphone still outputs sounds.

speakerOn = true : loud speaker
speakerOn = false: earpiece

Redefined ms_thread_exit to workaround a Bionic bug in earlier Android versions.

set player/recorder threads to high prio
