[0000/0010] cal: code revisit part I

[Sami Kerola <kerolasa@iki.fi>]

Hi Karel, and others,

I promised earlier to put some effort in making the cal(1) a little bit
less messy.  The patch set begins by adding a structure that contains
what user wants.  Last two changes are hopefully most interesting.  They
add run time configuration that is filled, and used later.

I got the --one and --three outputs working, but I am not completely
happy about the --three.  Quite frankly better function would take input
how many horizontal calendar outputs are needed, and would do exactly
that.  Such function would be more reusable when considering yearly
output, and the fact it has two column output when in julian mode.

Karel, it is be best not to merge the last patch.  It is more of
work-in-progress, comments would be great.
