- Add unzstd() and the zstd decompress interface. - Add zstd support to decompress_method(). The decompress_method() and unzstd() functions are used to decompress the initramfs and the initrd. The __decompress() function is used in the preboot environment to decompress a zstd compressed kernel. The zstd decompression function allows the input and output buffers to overlap because that is used by x86 kernel decompression.
