Add some menu items under Screen>Rotation to allow inverting
the default rotation of ImageViewer, and to auto-rotate for
best fit on launch, so landscape images are auto-rotated to
the preferred rotation.
* Get rid of the `canToggleGSensor` Device cap, it's now mandatory for `hasGSensor` devices. (This means Kindles can now toggle the gyro, fix#9136).
* This also means that `Device:toggleGSensor` is now implemented by `Generic`.
* Update the Screen & Gyro rotation constants to be clearer (c.f., https://github.com/koreader/koreader-base/pull/1568) (/!\ This might conceivably break some `rotation_map` user-patches).
* Input: Move the platform-specific gyro handling to Device implementations, and let Input only handle a single, custom protocol (`EV_MSC:MSC_GYRO`).
* Input: Refine the `rotation_map` disable method implemented in 43b021d37c. Instead of directly poking at the internal field, use a new method, `disableRotationMap` (/!\ Again, this might break some `rotation_map` user-patches).
* Input: Minor tweaks to event adjust hooks to make them more modular, allowing the Kobo implementation to build and use a single composite hook. API compatibility maintained with wrappers.
* Allow locking the gyro to the current screen mode (i.e., orientation).
* Tweak the "sticky rota" option to work both ways
* More rotation constant usage instead of magic numbers
* landscape FM / Refactor rotation
refactor and simplify the orientation handling code. the user generally cares about the rotation (what direction the device is facing) and not about if koreader is displaying in portrait or landscape mode
* bump base
update luasocket, libjpeg-turbo, curl
add logging to evernote-sdk-lua
update framebuffer for proper rotation
