John Keeping 3d8a6507ca filter: pass extra arguments via cgit_open_filter
This avoids poking into the filter data structure at various points in
the code.  We rely on the fact that the number of arguments is fixed
based on the filter type (set in cgit_new_filter) and that the call
sites all know which filter type they're using.
