7e6a222a8e usb serial: refactor serial number construction
Use new PIOS_USB_UTIL_AsciiToUtf8() function to compose the
USB serial number rather than repeating that code for each
board.

All boards now append "+FW" or "+BL" to their USB serial numbers
to allow the descriptors to differ between FW and BL images.

3e0a9bc47e usb: Change supported LANGID in USB descriptor to be English US
Some versions of Windows will ignore the USB device serial number
if the string is not delivered with LANGID = English US 0x0409.

This is true regardless of the configured locale of the machine.

19367730c0 usb: remove null termination on serial number string
The serial number string descriptor was incorrectly null
terminated.  The standard clearly states that there should
not be a null terminator.

Use new #defines to ensure that our strings are sized
properly.

d4b0475f6a usb-descriptors: add +BL or +FW suffix to serial number string
This makes the BL and FW images distinct devices with unique
serial numbers.

Windows (and maybe Mac) remembers the device descriptors and
the associated drivers based on this serial number.  Providing
unique serial numbers for the BL and FW images allows us to
provide different sets of descriptors for the BL and FW images
without confusing these OSes.

BL version number is now also bumped to reflect the new
serial number generation algorithm.

8d8715c8c1 copyright: add/correct GPL + copyright boilerplate
I missed some of the boilerplate text on some of the
new files I've added recently.  Fixed.

b94f4b49a4 usb: major refactoring of USB descriptors, CDC and HID
Summary of changes:
 * USB CDC and HID drivers are completely split apart.
   * This will allow different max buffer sizes for HID and CDC.
 * USB descriptors have been overhauled:
   * Proper structs/macros/enums declared for USB (see pios_usb_defs.h)
   * Two common descriptor definitions.  One for HID+CDC another for HID only.
     See pios_usb_desc_{hid_cdc,hid_only}.c for details.
   * Long standing bugs in OP USB descriptors became much more obvious with the
     new struct definitions.
   * Board specific USB initialization is now in pios_usb_board_data.h in each build target.
   * Definition of USB descriptors is now entirely indpendent of STM32 libs.
     Glue into STM32 libs is provided by pios_usbhook.c.
 * Removed a lot of stale/irrelevant USB #defines throughout the tree.
 * Improved naming consistency throughout USB code:
   * PIOS_USB_HID_* now refers to the HID endpoint code.
   * PIOS_USB_CDC_* now refers to the CDC endpoint code.
   * PIOS_USB_* now refers to the low-level USB code.
   * PIOS_USB_BOARD_* now refers to board-specific USB data
   * PIOS_USBHOOK_* is glue between PIOS and STM32 USB libs.
   * struct usb_* and enum usb_* and USB_* and HID_* are all types from the USB spec.
 * Shrunk the buffer size on the CDC call mgmt endpoint to save some RAM.
 * Made a few more USB related variables static to save some RAM.
