The new parser does not rely on Spark (which is now removed from our repo),
uses modern 3.x idioms and is significantly smaller and simpler.

It generates exactly the same AST files (.h and .c), so in practice no builds
should be affected.

and can't bootstrap the parser.

1. Make it work when invoked directly from the command-line. It was failing
   due to a couple of stale function/class usages in the __main__ section.
2. Close the parsed file in the parse() function after opening it.

Patch from Sven Brauch.

Patch from Taihyun Hwang.
