 n2, an alternative ninja implementation

CI status

n2 (pronounced "into") implements enough of ninja to successfully
build some projects that build with ninja.

I wrote it to explore some alternative ideas I had around how to
structure a build system.

Here's a small demo of n2 building some of Clang.

 Differences from Ninja

n2 is missing many Ninja features.

n2 does some things Ninja doesn't:

  * Builds start tasks as soon as an out of date one is found, rather
    than gathering all the out of date tasks before executing.
  * Fancier status output, modeled after Bazel.
  * -d trace generates a performance trace as used by Chrome's
    about:tracing or alternatives (speedscope, perfetto).
