efccf6c931 A few stylistic tweaks 
- `goto free_romx` -> the more typical `goto cleanup`
- `goto fail` -> the more typical `goto finish`
- Remove a redundant `todo` variable

21b59c4651 Reinstate PUSHS clearing the SECTION scope (#870) 
* Reinstate PUSHS clearing the SECTION scope

Otherwise you can use `PUSHS` to simulate the old `ds -21`, and possibly cause bugs

* Have PUSHS push LOAD block state as well

It does not make sense not to, and coud cause bugs.

3fdf01c0f5 Resolve some TODO comments 
- `out_PushSection` should not set `currentSection` to NULL because
  PUSHS, PUSHC, and PUSHO consistently keep the current section,
  charmap, and options, even though the stack has been pushed.

- `Callback__FILE__` does not need to assert that `fileName` is not
  empty because `__FILE__`'s value is quoted, and can safely be empty.

- `YY_FATAL_ERROR` and `YYLMAX` are not needed since the lexer is
  not generated with flex.

cb47ac8b97 Change the start position check on INCBIN 
Currently INCBIN gives an error if your start position == file size.
This means you cannot include an empty file.
It also means the text of the error message is incorrect
(as the start is not greater, but equal to the length of the file)

4f842a1248 Create specialized symbol finder functions 
The old "find symbol with auto scope" function is now three:
- One finds the exact name passed to it, skipping any checks
  This is useful e.g. if such checks were already performed.
- One checks that the name is not scoped, and calls the first.
  This is useful for names that cannot be scoped, such as checking for EQUS.
  Doing this instead of the third should improve performance somehwat, since
  this specific case is hit by the lexer each time an identifier is read.
- The last one checks if the name should be expanded (`.loc` → `Glob.loc`),
  and that the local part is not scoped. This is essentially the old function.

762474d3ac Let RGBASM write JR offsets in floating sections 
This requires some special-casing for `jr @` because the `jr` opcode has
already been emitted, but not the operand, so PC points to the middle.
Moved the RGBLINK test to RGBASM's folder, and created a new RGBLINK test.
