* Remove $debug global
and $vdebug global
makes these variables more accessible and protects from collisions.

* the on boot set sends application as the first parameter, just handle that

* Relocate other debug related functions

* Log debug to stdout

* Wrong output

* remove stupid constants

* Fix lint and style issues
