VITA Ds4vita experimental-hooks

New version is out!

It uses hooks instead of button emulation:
https://github.com/xerpi/ds4vita/releases.

Hook ctrl peek2 and read2 (PS4 remote play works, yay!)
Proper L2/R2 and L3/R3 support
Only overwrite front touchscreen
Reduce DS4 analog deadzone to 3

Add sceMotionGetState hook (thanks to @DavisDev)
Reduce ksceCtrlSetAnalogEmulation delay (should improve analog sensibility)

Fixed a bug which caused misbehavior when using other Bluetooth devices along with a DS4.

Fix kernel joystick emulation

Fix right analog up/down

Reduce emulated buttons duration (should feel more responsive now)
Call ksceCtrlSetAnalogEmulation with proper parameters
Reset input emulation data when disconnecting

Use ctrl emulation functons instead of hooking (buttons and analogs), this means that the PS button works now.

Reset auto-suspend timer when buttons or touch change.

Reduce thread stack and mempool sizes (smaller footprint)
Also map R2 to R and L2 to L
