Filter: Add bytestring type
...
- Rename BYTESTRING lexem to BYTETEXT, not to collide with 'bytestring' type name
- Add bytestring type with id T_BYTESTRING (0x2c)
- Add from_hex() filter function to create bytestring from hex string
- Add filter test cases for bytestring type

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.

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.

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.

Filter: renaming pointers for consistency

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

Filter: Some people can't pronounce "postfixify" correctly. Let's try "linearize" instead.

This is just a naming change.
