11a6a81169 Implement -Wtruncation=level (#931)
* Implement -Wtruncation=level

-Wtruncation=0 is the same as the current -Wno-truncation.
-Wtruncation=2 is the same as the current -Wtruncation.
-Wtruncation=1 is the new default; it's less strict, allowing
N-bit values to be between -2**N and 2**N (exclusive).

* Implement generic "parametrized warning" system

* Test more `Wtruncation` variants

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.

7a587eb7d6 Use midrule action values for captures' terminated status
Bison 3.1 introduces "typed midrule values", which would write
`<captureTerminated>{ ... }` and `$$` instead of `{ ... }` and
`$<captureTerminated>[1-9]`, but rgbds supports 3.0 or even lower.

ee5da4468d Fix interpolation/STRFMT overflow issues (#838)
Widths and fractional widths greater than 255 would overflow a
uint8_t and wrap around to smaller values.

Total formatted lengths greater than the avilable buffer size
would overflow it and potentially corrupt memory.

5d6e0677d9 Fix error-related issues (#773)
* Mark `error` as a `format` function, to properly scan its format

* Fix the call to error() from parser.y:
  - Use '%s' to avoid passing an arbitrary format
  - Simplify yyerror overall

* Fix size parameter of %.*s format being an int... bonkers standard.

* Report the number of arguments required and provided on a STRFMT mismatch

* Add an assert to check for a very unlikely bug

56071599e7 Allow trailing commas in bare lists
This applies to macro arguments, DB, DW, DL, DS,
PRINT, PRINTLN, EXPORT, PURGE, and OPT.

It also removes support for empty entries in DB/DW/DL.
(Deprecating it would require keeping parser support,
which is ambiguous with trailing commas.)
