[PATCH] cleanup virtual console <-> selection.c interface

Pass around pointers instead of indices into a global array between various
files of the virtual console implementation and stop using obsfucting
macros that expect certain variables to be in scope.

This is a first step to get rid of the various global arrays in the VC
code.
