Add prokind column, replacing proisagg and proiswindow

Browse Source 
The new column distinguishes normal functions, procedures, aggregates,
and window functions.  This replaces the existing columns proisagg and
proiswindow, and replaces the convention that procedures are indicated
by prorettype == 0.  Also change prorettype to be VOIDOID for procedures.
