1dcc000572 Report locations for RGBLINK errors with conflicting objects (#1494) 
This requires updating the object file format to record the
fstack context for sections themselves, not just for patches.

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.

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

e548ecc6fa Report attempts to assign a SDCC area in a way inconsistent with its data 
This actually avoids breaking the (segfaulting) invariant that
a section whose type "has data" has as many bytes of `->data` as
its `->size`.

00b0914436 Reserve space to avoid file sym array realloc 
This line was missing; in its absence, as soon as the array reallocs,
all registered symbol pointers are invalidated, leading to a crash
(e.g. when generating a sym file).

Made the reallocation check into a hard error, too.
Since fileSymbols gets registered with each section, we would have to
change that, and then it cascades throughout all of RGBLINK.
This will be handled correctly in the Rust port.
