strtok stores its values in thread local storage.
So it can not guarantee works well when multithread environment.
AudioFlinger has multithread.
so strtok_r is more safe.

Uninitialized pointer can cause crash.

mpAudioTrack should be initialized in any case.
If getOutputSamplingRate returns ERROR, this won't be initialized.
As a result, deleting this field in dtor can cause crash.

Fix crash in MyHandler when sockets are not set.

-When going quickly in and out of the video view during an rtsp
streaming session, a race condition occurs and MyHandler tries to
connect to a socket that has been reset. To avoid this,
checks are added.
- If there are errors during setupTrack 1, it is no use
setting up track 2. It will cause new errors.
- No assert for socket connect since there is a normal
status check already.
