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

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.
