- Move source code from `trunk` into root directory. - Update build files and ASM include paths. Add SPDX license header where appropriate. - These changes also update the CI build files in `.gitea/workflows/`. - Note: Line endings standardised from `CRLF` > `LF`, so best to view diffs with whitespace changes hidden. (Work towards [#75](KolibriOS/kolibrios#75), point 3) --------- Co-authored-by: Burer <burer@kolibrios.org> Reviewed-on: KolibriOS/kolibrios#425 Reviewed-by: Mikhail Frolov <mixa.frolov2003@gmail.com> Reviewed-by: Burer <burer@kolibrios.org> Co-authored-by: Andrew <dent.ace@gmail.com> Co-committed-by: Andrew <dent.ace@gmail.com>
