xz: add RISC-V BCJ filter A later commit updates lib/decompress_unxz.c to enable this filter for kernel decompression. lib/decompress_unxz.c is already used if CONFIG_EFI_ZBOOT=y && CONFIG_KERNEL_XZ=y. This filter can be used by Squashfs without modifications to the Squashfs kernel code (only needs support in userspace Squashfs-tools).

xz: remove XZ_EXTERN and extern from functions XZ_EXTERN was used to make internal functions static in the preboot code. However, in other decompressors this hasn't been done. On x86-64, this makes no difference to the kernel image size. Omit XZ_EXTERN and let some of the internal functions be extern in the preboot code. Omitting XZ_EXTERN from include/linux/xz.h fixes warnings in "make htmldocs" and makes the intradocument links to xz_dec functions work in Documentation/staging/xz.rst. The alternative would have been to add "XZ_EXTERN" to c_id_attributes in Documentation/conf.py but omitting XZ_EXTERN seemed cleaner.
