5f07095f6d Implement INCLUDE_ONCE directive (#1481) 
Identify files by (device, inode), not by path, so that symlinks,
relative paths, case-insensitive paths, or other edge cases
do not result in double includes.

610f04beeb Fix condition for assuming at EOF 
Part of that condition's purpose is to ensure that we read the correct
lexer state; but it's possible now for the fstack to be non-empty
*before* the lexer state is registered, i.e. if there is an error
in the function that registers it.
This causes a NULL pointer deref.

2706f94788 Multiple fixes and enhancements to RPN behavior: (#1448) 
- FIX: `Label & const` was not actually doing the `& const` masking
  (fixes #1446)
- ADD: `LOW(Label)` can be constant if `Label` is aligned to 8 or more bits
  (resolves #1444)
- ADD: `!expr` can be constant 0 if `expr` has any non-zero bits
  (resolves #1447)
- `LOW()` and `HIGH()` have their own RPN operator values
  (resolves #1445)

The change to RPN values means that the object file version was incremented.

This also refactors unary operators and functions, combining their
evaluation similarly to binary ones.

9ab3446d1a Fix two bugs with RGBASM fixed-point math (#1388) 
- Fixed-point formulas are implemented using IEEE-754 floating-point
  internally, which could give infinity or NaN values whose conversion
  to fixed-point integer was platform-dependent.
- Formatting fixed-point $8000_0000 (INT32_MIN, -2147483648) was
  not putting the negative sign in front.
