cf85146353 Refactoring and enhancements to RGBASM warnings (#1526) 
* Allow a `no-` prefix to negate "meta" warnings
  (`-Wno-all`, `-Wno-extra`, `-Wno-everything`)
* Allow `-Wno-error=...` to override `-Werror`
  (including for "meta" warnings)

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.

6b8d33529e Improve string/interpolation formatting (#1491) 
- The '#' component for type 's' now escapes the string characters
- The '#' component for type 'f' now prints a precision suffix
- The new 'q' component specifies a precision value

57c3d74b9e Use a custom generic tagged union Either instead of std::variant for efficiency (#1476) 
* Implement custom generic tagged union `Either`

This should be more efficient than `std::variant`, while still
keeping runtime safety as it `assert`s when `get`ting values.

* Use `Either` for RPN expressions

* Use `Either` for file stack node data

* Use `Either` for `File` buffer

* Use `Either` for `STRFMT` args

* Use `Either` for RGBLINK symbol values

* Support an equivalent of `std::monostate` for `Either`

* Use `Either` for lexer tokens

* Use `Either` for symbol values

* Use `Either` for lexer mmap/buffer state

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.

39e9315e8a Use a smaller size for the lexer buffer 
Large sizes are more efficient when it's actually buffered,
but most of the time `mmap` is used instead, and the extra size
just slows down allocation of lexer states.
