This commit fixes a bug that eats one tap event after the clickpad button has been pressed and released with no fingers lifted, turned into palm, or palms lifted, e.g. by pressing it with a non-finger object or with an otherwise ignored palm that stays down. After one tap is eaten, the state machine would get un-stuck from its DEAD state and end up in IDLE as it is supposed to, permitting subsequent taps to have their intended effect. However, that would even happen when the clickpad button was still held down, which is also wrong. The correct solution is to exit to IDLE when both the button and all touches are up. This is achieved by splitting the DEAD tapping state into one state for the button down (BUTTON) and one for the button up (DEAD). Working around this (in the case of a button pressed by a palm lifted afterwards) was the only remaining justification for the palm up event, which this commit also removes.

libinput
libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.
libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.
User documentation
Documentation explaining features available in libinput is available here.
This includes the FAQ and the instructions on reporting bugs.
