Add processing IO located on the sides of some chips. These are IOBUF,
which are converted into IBUF and OBUF not by fuses, but by signaling to
OE.
Also added the creation of a Global Set / Reset for all chips, instead
of a list of tile types, information from the apicula database is used,
and minor fixes.

- The global router is modified to work out the routing of PLL outputs and inputs;
- Added API function to change wire type after its creation - there was
a need to unify all wires included in the node at the stage of node
creation, when all wires have already been created.

Shamelessly adapted gatecat's router.
Very early version, not yet puzzled with recognizing clock sources and
controlling the type of wires involved.
