* Fix compilation with -Wsign-conversion
For tests with GCC and Clang
Fixes https://github.com/ETLCPP/etl/issues/632
* Fix support of negative Id in type_lookup.h: type_from_id
* Fix element access arithmetic in atomic_gcc_sync.h fetch_add/fetch_sub
* Fix rounded_integral_division.h: divide_round_half_odd(): direction is always 1
* Deduce underlying storage size when constructing string_ext from char[].
This removes the need for passing sizeof(storage) to the constructor.
* Add array constructors for the other string types.
- u16string_ext
- u32string_ext
- u8string_ext
- wstring_ext
* Add additional constructors to match existing API.
* Fix inconsistent test argument order.
