Convert all code to Linux coding style

After so many years of silence, we don't expect the original author to
return to the project.  To make things a bit simpler for us, we convert
the coding style to what we are used to (Linux style).

The conversion was made using the 'Lindent' script which is part of the
Linux kernel.
