ab9945c1ee Avoid using fscanf to detect RGBDS object files 
This function is made for text, e.g. accepts spaces, leading zeros, etc. before `%u`.
This way checks that the correct amount of bytes are read instead.

828b2adcdf Make RGBLINK able to link SDCC object files 
This requires a LOT of tricky code, mostly due to the format itself being,
er, not the most straightforward.
Everything is converted to existing RGBLINK concepts (sections, patches,
etc.), so the core code is essentially unchanged.
(A couple of genuine RGBLINK bugs were uncovered along the way, so some of
the core code *is* changed, notably regarding `SECTION FRAGMENT`s.)

All of this code was clean-roomed, so SDCC's GPLv2 license does not apply.

8b1cc72f09 Added scramble flags to RGBLINK. (#921) 
* Add scramble flags to RGBLINK

-S and -W will scramble ROMX and WRAMX respectively.

* Modify scramble CLI

CLI now takes a list of comma-separated values.
Added arg_error to clean up messages.

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.

7e7f92f18c Assign section locations to all UNIONs/FRAGMENTs 
Fixes the test case from #800

The `out.gb` output was corrected, since the two "test"
fragments have a different order in ROM than in SRAM.
It is effectively:

; ROM0[$0000], fragments ordered by size
    jr Label
    dw Label
    db 0

; SRAM[$a000], fragments ordered by .o order
    ds 1  ; db 0
    ds 2  ; jr Label
Label:    ; $a003
    ds 2  ; dw Label
