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 filetype strings are not really suitable for shell scripts, so
add a shortname array of filetypes usable for shell scripts.

We may have some disk with MBR as a first sector. In this case, the
current FAT check returns an error. However, the FAT sector exist and
the MBR can tell us where it is.
This patch add to file_name_detect_type function the ability to find
the FAT boot sector on the first sector of the first partition in case
it is not on sector 0.
It also introduce is_fat_or_mbr to check if a buffer is a FAT boot
or MBR sector

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

Add functions to read the barebox_arm_head, check barebox magicword
and read out the barebox image size.
Create a inital partion of 1Mb to access the barebox image on nand.

This is a brown paper bag type of bugs. Do not assume that a file
has to be at minimun 512 bytes to be detectable.

Several filetypes can be autodetected. Barebox could make use
of this in several ways:
- Add a command to detect filetypes
- detect arm zImages and uImages to unify the different boot commands
- maybe detect UBI or JFFS2 images to construct parts of the kernel
command line
- select correct uncompression function based on filetype
This patch adds basic support to detect filetypes.
