Landscape FM / Refactor rotation (#6309) 
* 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
