Clean up the Lua API, make it luajit-only, no C

This removes the libcough which was a temporary layer atop
the libpneum to make it synchronous. Now Lua API only requres
luajit, and has no dependencies on compiling any C.
Also comment out a couple of debug print functions.

 xhyve VM on a Macbook Pro, so I would not take the performance numbers for granted :)
