Ondrej Zajicek (work) a2527ee53d Filter: Improve handling of stack frames in filter bytecode
When f_line is done, we have to pop the stack frame. The old code just
removed nominal number of args/vars. Change it to use stored ventry value
modified by number of returned values. This allows to allocate variables
on a stack frame during execution of f_lines instead of just at start.

But we need to know the number of returned values for a f_line. It is 1
for term, 0 for cmd. Store that to f_line during linearization.

Ondrej Zajicek (work) 26bc4f9904 Filter: Implement direct recursion
Direct recursion almost worked, just crashed on function signature check.
Split function parsing such that function signature is saved before
function body is processed. Recursive calls are marked so they can be
avoided during f_same() and similar code walking.

Also, include tower of hanoi solver as a test case.

Ondrej Zajicek (work) 93d6096c87 Filter: Implement type checks for function calls
Keep list of function parameters in f_line and use it to verify
types of arguments for function calls. Only static type checks
are implemented.

The struct f_inst * is now always "what"
and the union member pointer is always "whati".

This should help filter performance a bit.

Jan Maria Matejka 23e3b1e665 Filter: Some people can't pronounce "postfixify" correctly. Let's try "linearize" instead.
This is just a naming change.

This should be revised, there are still ugly things in the filter API.
