Tim Edwards ac209d2397 Corrected a bunch of typos (different signal names used in the 
same file), errors (buffer output pin name, power supplies not
passed at the top level).  Corrected a major error that prevented
the use of the buffers in simulation, so this was not previously
verified by simulation.  The buffering has now been properly
verified.

Tim Edwards f7ec0cd012 Added buffers to the top level, inside a macro called 
gpio_signal_buffering (gpio_signal_buffering_alt in caravan).
Note that this macro requires manual placement and routing, like
the padframe, and the top level will need to route around its own
internal routes.
