[PATCH 03/13] cal: add input variable names to function prototypes

[Sami Kerola <kerolasa@iki.fi>]

While prototypes such as 'function(int, int, char, int);' are legal they
do not help when trying to understand how the function is expected to be
used.  Adding variable names gives at least a hint when looking the
prototypes.
