Add native java screenrecorder/global action for screenrecording. [1/2]
Mad props to 0xD34D and the ChameleonOS Team for the masterful work.

This is double commit combining the following:

PART 1: Add native java screen recorder [1/2]
This is based on the screenrecorder binary found in frameworks/av.
It has been converted to a native library with the necessary jni
hooks for interfacing withit via a ScreenRecorder java class.

Volume up + power chord is used to start and stop recording by
binding to the service found in the ScreenRecorder app:
https://github.com/ChameleonOS/android_packages_apps_ScreenRecorder

PS1:
Clean up white space.

PS2:
Fix naming convention for state field.

PS3:
Rebase

PS4:
Post mScreenRecordTimeout with 1000 millisecond delay instead
of 10000.

PS5:
Send record screen broadcast instead of using the service
directly.

PS6:
SCREEN_RECORDER_FRAMERATE should be SCREEN_RECORDER_BITRATE
