This patch offers a read/write implementation for barebox. The code
does not exaclty match barebox coding style, but works nicely and
should be ready to give it a try.

If we register a device we have to unregister it later when
the driver did not accept the device. Also, do not forget to
free the backingstore string.

This makes it possible to compile without devfs. devfs_create/devfs_remove
is used by drivers and thus must still be present even without devfs support.
Also, this patch adds cdev_open/cdev_close/cdev_flush/cdev_ioctl calls to
work with devices without using the file api.

Otherwise we end up with errno not being set correctly
if a filesystem driver uses the standard open/close/read/write
functions to access its backing store.

We need to assign a new device id if we want to register
a fs with the same type of an already registered fstype.

This patch adds some basic file descriptor sanity checks to the file access
routines. Check whether the given file descriptor is in the files array range,
and whether the file entry is valid.

Strip /dev/ part of backing store before passing cdev_by_name, as
cramfs_probe() will otherwise always fail.

Add an open counter for device files so that we cannot accidently
remove an opened device. This happened with bb devices.

We can't truncate device files. Make sure that if we want to
write beyond the device that the bytes that still fit into the
device get written.

When a nor0 devices has no partitions assigned, then a call to
open() to create a file will jump with a NULL fct ptr.
Much more cheching code is missing and pointers to function are
jumped without any NULL ptr check. This must be fixed as well later.

this fixes:
fs/fs.c:210:6: warning: symbol 'files' was not declared. Should it be static?
fs/fs.c:212:6: warning: symbol 'get_file' was not declared. Should it be static?
fs/fs.c:227:6: warning: symbol 'put_file' was not declared. Should it be static?

- Use device tree structure to implement partitions
- Let devinfo print a nice tree
- Introduce 'fixed' partitions which are not removable
- Fix mount: It was not possible to mount on a relative path.
