[PATCH] Wrap all protocols except for synaptics w/ ifdefs

[Andres Salomon]

This patch allows ALPS, LOGIPS2PP, LIFEBOOK, and TRACKPOINT protocol
extensions to be disabled during compilation.  The synaptics stuff is left
alone for now, since it needs special handling for synaptic pass-through
ports.
