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.

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.
All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.
Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.

This patch adds the support for high speed in usb device framework and usbtty
driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board
configuration files have to define this macro to enable high speed support.
Along with that specific peripheral drivers also need to define a function to
let the framework know that the enumeration has happened at high speed.
This function prototype is "int is_usbd_high_speed(void)"

In 9792987721 Stefan describes a usecase
where the previous behavior of leaving wMaxPacketSize be unaligned
caused fatal problems. The initial fix for this problem was incomplete
however as it showed another cases of non-aligned access that previously
worked implicitly. This switches to making sure that all access of
wMaxPacketSize are done via (get|put)_unaligned.
In order to maintain a level of readability to the code in some cases
we now use a variable for the value of wMaxPacketSize and in others, a
macro.

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.

V3: Fixed line-wrap problem due to user error in mail!
Added usb_configured() checks in usbtty_puts() and usbtty_putc() to get around a hang
when usb is not connected and the user has set up multi-io (setenv stdout serial,usbtty etc).
Got rid of redundant __attribute__((packed)) directives that were causing warnings from gcc.

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.
