Cleanup: return cylinder from cylinder_start() in parser

Browse source 
Most callers of this function accessed the newly generated cylinder
immediately after calling this function. Thus, for convenience,
return the added cylinder. This avoids a number of verbose expressions.

On the flip side, cylinder_start() now has to be cast to
function returning void in a the "nesting" function table.
