By this commit user gets possibility to register USB
device satutus callback. This callback represents device state
and is added so user could know what happend to USB device.
Callback is registered by providing it to usb_enable()
USB api is extended by this callback handler.
Samples using using USB are by default provide no callback
and the usb_enable() is called with NULL parameter.
Status callback registered by hid class is deleted as now
USB device has global callback for all classes within device.

USBD_CFG_DATA_DEFINE macro has not consider that a class
could have more than one set of usb_cfg_data struct.
If a class has more than one set of usb_cfg_data
then they should be sorted the same way like by
USBD_DEVICE_DESCR_DEFINE macro.

As seen previously, some toolchain are willing to insert padding
at section changes to apply greater alignments by default. This is
especially true with 64-bit builds. USB structures are marked with the
packed attribute and therefore the linker section they land into
must also be byte aligned.

In order to unify the legacy and composite code, move the class and
vendor request handler buffer into the USB device code, just like in
composite mode. The option is renamed from USB_COMPOSITE_BUFFER_SIZE
into USB_REQUEST_BUFFER_SIZE and also replaces the USB_DFU_MAX_XFER_SIZE
and USB_HID_MAX_PAYLOAD_SIZE options.

This patch adds USB descriptor and data section macros.
Use USBD_DESCR_..._DEFINE macros to place the parts of USB device
descriptor in predetermined order in the USB descriptor
section. The parts of a device descriptor are also
sorted according to the macro argument. All parts of a
particular device descriptor must use the same argument.
Use USBD_CFG_DATA_DEFINE macro to place the data struct
of a class driver or function in the USB data section.

This patch lets a C++ application use more of Zephyr by adding guards
and changeing some constructs to the C++11 equivalent.
Changes include:
- Adding guards
- Switching to static_assert
- Switching to a template for ARRAY_SIZE as g++ doesn't have the
builtin.
- Re-ordering designated initialisers to match the struct field order
as G++ only supports simple designated initialisers.

The transfer API provides 'high' level functions to manage sending and
reception of USB data. A USB (class) driver has to register the generic
usb_transfer_ep_callback as endpoint status callback in order to use
the API.
With this API, the class driver does not need to take care of low-level
usb transfer management (packet splitting, ZLP, synchronization...).
The usb_transfer methods will split transfer into multiple transactions
depending endpoint max size and controller capabilities.
Once the transfer is completed, class driver is notified by a callback.
The usb_transfer method can be executed in IRQ/atomic context.
A usb_transfer synchronous helper exists which block-waits until
transfer completion.
In write case, a transfer is complete when all data has been sent.
In read case, a transfer is complete when the exact amount of data
requested has been received or if a short-pkt (including ZLP) is
received.
transfer methods are thread-safe.
A transfer can be cancelled at any time.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types. This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies. We also convert the PRI printf formatters in the arch
code over to normal formatters.

The functions that implement usb_request_handlers are already using an
int32_t for transfer_len, so lets make the typedef match. This address
a potential issue in the future when the typedef of int32_t changes (or
when building with newlib).

USB class drivers may need to offload some work from
upcall interrupt context to a background fiber. This
requires some way to defer taking more data from host
till the offloaded work completes. Two APIs are added to
achieve this.
Further USB class drivers sometimes need to set STALL condition
on end-points to signal errors to host.These too are
added.
