fix build breakage
1. Add a missing field and a function
2. Disable the deprecated attribute in Android temporarily to
allow us to use "pcm_read/write" which are deprecated upstream
3. Remove an unused define and an include in mixer.h
4. Add mixer_ctl_event and copy the snd_ctl_event to mixer_ctl_event
5. Add pcm_ioctl function and mark as deprecated function
