At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.
For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.
Instead, add a stdio_dev pointer to each of the stdio member functions.
Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.
Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

There is no point in setting a structure's memory to NULL when it has
already been zeroed with memset().
Also, there is no need to create a stub function for stdio to call - if the
function is NULL it will not be called.
This is a clean-up, with no change in functionality.

So far the console API uses the following naming convention:
======Extract======
typedef struct device_t;
int device_register (device_t * dev);
int devices_init (void);
int device_deregister(char *devname);
struct list_head* device_get_list(void);
device_t* device_get_by_name(char* name);
device_t* device_clone(device_t *dev);
=======
which is too generic and confusing.
Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev
This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
