Filter: Apply constant promotion for FI_EQ / FI_NEQ
...
Equality comparison is defined on all values, even of different
types, but we still want to do constant promotion if possible.

Filter: Add literal for empty set
...
Add literal for empty set [], which works both for tree-based sets
and prefix sets by using existing constant promotion mechanism.

Filter: Ensure that all expressions declared return type
...
All instructions with a return value (i.e. expressions, ones with
non-zero outval, third argument in INST()) should declare their return
type. Check that automatically by M4 macros.
Set outval of FI_RETURN to 0. The instruction adds one value to stack,
but syntactically it is a statement, not an expression.
Add fake return type declaration to FI_CALL, otherwise the automatic
check would fail builds.

Filter: Fix typecheck for AND/OR.
...
Do not apply dynamic type check for second argument of AND/OR, as it is
not evaluated immediately like regular argument would be.
Thanks to Mikael for the bugreport.

Filter: Better constant promotion
...
We use constant promotion from IPv4 to Router-ID values, as they have
same literals. Instead of ad-hoc code in filter instructions, add
constant promotion code to parse-time typecheck code.

Filter: Parse-time typechecks

Most expressions can be type-validated in parse time. It is not
strong enough to eliminate runtime checks, but at least one gets
errors immediately during reconfigure.
