Notable changes: - Split in multiple files the existing revng-merge-dynamic script - Add the option to merge additional LOAD segments in the resulting binary - Align the new .dynstr to a 4 byte boundary - Ensure the last verneed entry is marked as such (vn_next == 0) - Ensure LOAD PHDRs are listed in ascending order, as mandated by ELF spec
