Rename several MSDOS database files to add category prefixes and reorganize one entry into db_extra. No content changes (100% similarity); this is a file-structure cleanup to make types explicit:
- db/MSDOS/Power_C.4.sg -> db/MSDOS/compiler_Power_C.4.sg
- db/MSDOS/CauseWay_DOS_Extender.0a.sg -> db/MSDOS/extender_CauseWay_DOS_Extender.6.sg
- db/MSDOS/Copy_Protector.2.sg -> db/MSDOS/protector_Copy_Protector.2.sg
- db/MSDOS/Copylock_PC.1.sg -> db/MSDOS/protector_Copylock_PC.2.sg
- db/MSDOS/FCP_IV.2.sg -> db_extra/MSDOS/packer_FCP_IV.2.sg
Renamed and moved numerous .sg files in the db directory to follow a more consistent naming convention and directory structure, grouping by type (e.g., compiler, cruncher, packer, protector, etc.). This improves maintainability and clarity of the signature database organization.
Several detection rule files were moved from db/ to db_extra/ for COM, ELF, MSDOS, and PE formats. Minor code style and comment updates were made to some scripts, and the about.txt file in db_extra was updated for clarity. The PE/Break_Into_Pattern.2.sg rule was renamed to Break-Into-Pattern.
