filter: revamp to create device-specific filters, rather than accel functions
The previous approach to pointer acceleration was to initialize the same
motion filter behavior but a different acceleration profile depending on the
hardware (the profile converts a speed to a multiplier for input deltas).
To be more flexible for hardware-specifics, change this into a set of specific
pointer acceleration init functions. This patch has no effective functional
changes, they're still all the same.
The acceleration functions are kept for direct access by the ptraccel-debug
tool.
