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.
