Fixed the wrong timestamps issue about camera recording

On emulator, the camera video recording crashes randomly.
It's caused by wrong timestamp when encoding the video frame.
The element of the vector is erased before accessing it.
Therefore, when reading the timestamp from the element,
the memory of the element has been changed.

Prevent AudioCommands being freed before read

When AudioCommandThread::threadLoop process AudioCommands it was
possible for it to delete a command where the posting thread still
hadn't read that status from it.

If a second command signaled the thread loop to continue after it
had inserted a new command while the thread loop was actually waiting
for the first command to report that it had read the status the
thread loop would continue and delete the first command.

Changed the wait condition when waiting for the calling thread to
read status to use command->mCond instead of mWaitWorkCV. This way
it's guaranteed that the signal to continue comes from the correct
thread.

Set u.ext_data to null after it has been freed

SEGV_MAPPER crash could happen in MetaData::typed_data::freeStorage.
The faulty address could be both random pointers and deadbaad. It
seems like free could be called more than once on u.ext_data. Set
u.ext_data to null after it has been freed as there already is a
null check before trying to free it.
