This patch adds support for extracting LZ4-compressed kernel images,
as well as LZ4-compressed ramdisk images in the kernel boot process.
This depends on the patch below

Pass the buffer size to the file detection code. This makes sure we do not
read past the buffer. This is especially useful for ext filesystem detection
as the magic is at byte offset 1080. Also introduce a FILE_TYPE_SAFE_BUFSIZE
define which is set to the minimum bufsize the detection code needs to detect
all known filetypes.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

As uncompress_size is a static and will set if call uncompress_size multiple
time.

uncompress_buf is used each time uncompress is called, so
make sure it is initialized correctly so that we do not
call free() on an already free pointer.

uncompress() has the same prototype as the various kernel decompress
functions. It automatically detects the compression type and selects
the correct uncompress function.
