2018-11-29base: Rename unit test cc files to be *.test.cc.Gabe Black
This makes the name easier to read, looks ok if the file is named with underscores between words or not, is easy to grep for, and shouldn't introduce any ambiguities in the file names.

2018-06-21base: Add a class which encapsulates Fibers.Gabe Black
This class encapsulates the idea of a Fiber in such a way that other implementations can be substituted in in the future. This implementation uses the ucontext family of functions. This change also adds a new unit test which exercises the new class. It creates three new fibers which accept a sequence of other fibers to switch to, one after the other. The main test function switches to the these fibers which switch with each other and occasionally back to the main fiber. Each time a test fiber is activated, it checks against a list which shows the correct order for the fibers to run in. When the main fiber gets control, it makes sure that list has been progressed through by the correct amount.
