Framebuffer and NativeActivity

Browse Source 
What was added:
* Framebuffer
* NativeActivity
* NV Services
* IOCTL Handler
* NV Devices:
* * /dev/nvmap - 0xC0080101, 0xC0080103, 0xC0200104, 0xC0180105, 0xC00C0109, 0xC008010E
* * /dev/nvhost-as-gpu
* * /dev/nvhost-channel - 0x40044801, 0xC0104809, 0xC010480B, 0xC018480C, 0x4004480D, 0xC020481A, 0x40084714
* * /dev/nvhost-ctrl
* * /dev/nvhost-ctrl-gpu - 0x80044701, 0x80284702, 0xC0184706, 0xC0B04705, 0x80084714
* SVCs:
* * SetMemoryAttribute
* * CreateTransferMemory
* * ResetSignal
* * GetSystemTick
* Addition of Compact Logger
What was fixed:
* SVCs:
* * SetHeapSize
* * SetMemoryAttribute
* * QueryMemory
* A release build would not set CMAKE_BUILD_TYPE to "RELEASE"
* The logger code was simplified
