Param count mismatch errors are on now

[Leopold Toetsch]

As discussed since quite a time and specced in pdd03, param count
mismatches throw an exception. Use :optional or :slurpy args if needed,
or just fix function calls and/or .param directives to prevent that
error. Below is a list of currently (r11570) failing core tests. Please
note that return/result count mismatches are still not checked.

Fixes welcome, I'll try to resolve some too.
