Drop the explicit S3SaveState protocol and opcode management; instead, create ACPI S3 Boot Script opcodes for the WRITE_POINTER commands with QemuFwCfgS3Lib functions. In this case, we have a dynamically allocated Context structure, hence the patch demonstrates how the FW_CFG_BOOT_SCRIPT_CALLBACK_FUNCTION takes ownership of Context.
