Added new TOTAL_NUM_CONFIGURATIONS option, removed USE_SINGLE_DEVICE_CONFIGURATION compile time option (but silently convert it to USE_SINGLE_DEVICE_CONFIGURATION internally for compatibility).

Added new USE_FLASH_DESCRIPTORS compile time option. By default, descriptors can now lie in mixed memory spaces (specified by a new parameter to the CALLBACK_USB_GetDescriptor() function) unless one of the USE_*_DESCRIPTORS compile time option is specified.

* - Added new FAST_STREAM_TRANSFERS compile time option for faster stream transfers via multiple bytes copied per stream loop
* - Added stdio stream demo code to the low-level CDC demo, to show how to create standard streams out of the virtual serial ports
* - Added new EEPROM and FLASH buffer versions of the Endpoint and Pipe stream functions
* - Added new USE_FLASH_DESCRIPTORS and TOTAL_NUM_CONFIGURATIONS compile time options
*
* <b>Changed:</b>
* - Deprecated psuedo-scheduler and removed dynamic memory allocator from the library (first no longer needed and second unused)

* - Dataflash_WaitWhileBusy() now always ensures that the dataflash is ready for the next command immediately after returning,
* no need to call Dataflash_ToggleSelectedChipCS() afterwards
* - Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case
* - The device-mode CALLBACK_USB_GetDescriptor() function now has an extra parameter so that the memory space in which the requested
* descriptor is located can be specified. This means that descriptors can now be located in multiple memory spaces within a device.
*
* <b>Fixed:</b>
* - Changed bootloaders to use FLASHEND rather than the existence of RAMPZ to determine if far FLASH pointers are needed to fix
