Major re-write of the recently-committed Synaptics Touchpad driver, prompted by jittery and/or random movement during tap gestures, lack of edge motion, and a general desire to make use of the extra features available with the native protocol. - Ditch the kernel thread; it was overkill for the small amount of processing required to deal with touchpad events. - If we fail to probe a Synaptics touchpad, issue a RESET command to ensure that whatever device is out there is left in a sane state (thanks to Reinoud Zandijk for the hint). - Completely re-write gesture support. - Put the touchpad in 80 packets per second mode and count them so they can be used to time gesture durations (instead of using mono_time). - Enhance up/down button support with options to use them to emulate the middle button or Z-axis events (like a traditional wheel mouse). - Add 'edge motion'. If a drag gesture is in progress, and the reported finger position moves to the touchpad's border region, continue to report movement events at a fixed rate as if the finger carried on moving in the same direction. This restores some functionality usually provided by the touchpad's firmware in PS/2 mode. - Filter successive movement events to reduce jitter. When scaling movement events, fold the remainder into the next event to prevent loss of information during slow/small finger movements. Pointer movement is now much more refined. - Add support for touchpads which can report more than one finger on the pad simultaneously. Optionally use this feature for middle/right button emulation (i.e. tap two fingers to emulate middle button). This feature is disabled by default (for now) to avoid surprise pasting of clipboard text. ;-)
