e1f0a13e5a Allow defining local labels for another scope (#1159) 
fix #1157 for the following source code

```
section "hSAVE_locals",HRAM
func3.hSpam: ds 1  ; no longer produces an error
;.hEggs: ds 1      ; uncomment this to see the new error

section "demo",ROM0
func3:
  ldh a, [.hSpam]
  ret
```

Remove two errors:
- `Not currently in the scope of 'func3'`
- `Local label 'func3.hSpam' in main scope`

Add one error:
- `Relative local label '.hSpam' in main scope`

a47da5f71f Deprecate __FILE__ and __LINE__ (#1072) 
Unlike C, these constants are not convenient for logging in macros,
since they always report the same data (their location in the macro).

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

80a376f045 Syntax errors resets the lexer right away 
`DEF`, `REDEF`, etc disable EQUS expansion, and reading
macro or OPT arguments sets the lexer to raw mode.
Syntax errors resume normal parsing at the line's end,
but should resume normal tokenization even before that.

0068c1375c Syntax error message hints to indent macro invocations 
This message is only printed for identifiers parsed as
`T_LABEL` (since they're at the start of a line) but
already defined as macros. Otherwise it may not be
relevant, e.g. for `MyLabel;:` or `My Label::`.
