Sergiusz Bazanski 0816f447b7 Make ice40::Arch thread-safe 
We move all non-chip data to be private and guard them with an R/W
mutex.

We then modify all calls that access these fields to lock/shared_lock
the mutex as required.

Profiling the code before and after is an exercise left to the reader
:).

This commit also includes changes to jsonparse to allow it to
1) recognize ports with no connection, and set their net pointers to NULL
2) recognize designs with a ports node rather than a ports_direction

The rule checker has also been modified to accommodate possible NULL netlists

The ice40 chip now also has iterator operations ++bi and bi++.
