Serial library revamping (64-bit etc) & Creation of a test suite

by Gottfried Haider for Processing

The Serial library in Processing needs to be revamped in order to get ready for the 2.0 release. I plan to add support for 64-bit architectures, fix long outstanding issues and test it across all supported platforms. Additionally, I propose to create validation tests, that would also allow to assess latency and throughput in real-life situations. Additional ideas are listed below.
