Unbreak tap compilation on OS X

Currently compiling the tap sources breaks on Mac OS X. This is because of:

  1) tap-linux.h requiring Linux includes
  2) typos
  3) missing #includes

This patch adds what's necessary to compile tap happily on Mac OS X.
I haven't tested if using tap actually works, but I don't think that's a
major issue as that code was probably seriously untested before already.

I didn't split the patch, because it's only a few lines of code and
splitting is probably not worth the effort here.
