android_stub: avoid vending in unused headers

Browse source 
Drop the redundant headers from libsystem and libnativewindow:
- include/android_stub/android/hdr_metadata.h
- include/android_stub/system/camera.h
- include/android_stub/system/radio.h
- include/android_stub/system/thread_defs.h

* A set of bit masks for specifying how the received preview frames are

* ^ ^ ^
* | | |---------> determine whether the callback is enabled or not
* | |-----------> determine whether the callback is one-shot or not

* WARNING: When a frame is sent directly without copying, it is the frame
* receiver's responsiblity to make sure that the frame data won't get
* corrupted by subsequent preview frames filled by the camera. This flag is
* recommended only when copying out data brings significant performance price
* and the handling/processing of the received frame data is always faster than
* the preview frame rate so that data corruption won't occur.
*
* For instance,
* 1. 0x00 disables the callback. In this case, copy out and one shot bits
* are ignored.
* 2. 0x01 enables a callback without copying out the received frames. A
* typical use case is the Camcorder application to avoid making costly
* frame copies.
* 3. 0x05 is enabling a callback with frame copied out repeatedly. A typical
* use case is the Camera application.

*
* This maps directly to the "nice" priorities we use in Android.
* A thread priority should be chosen inverse-proportionally to
* the amount of work the thread is expected to do. The more work
* a thread will do, the less favorable priority it should get so that
* it doesn't starve the system. Threads not behaving properly might
* be "punished" by the kernel.
* Use the levels below when appropriate. Intermediate values are
* acceptable, preferably use the {MORE|LESS}_FAVORABLE constants below.
