Copy out the EndpointStream and PipeStream functions to each architecture, so that each architecture can optimise the stream functions according to the available hardware (such as DMA, where available).

Initial restructuring of the core USB driver module to support multiple architectures in the future.

Altered all endpoint/pipe stream transfers so that the new BytesProcessed parameter now points to a location where the number of bytes in the transfer that have been completed can be stored (or NULL if entire transaction should be performed in one chunk).

Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.

Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.

Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).

Cache the USB_DeviceState variable internally in the library core when multiple checks are required in a single loop iteration, to reduce compiled code size.

Fixed SET FEATURE and CLEAR FEATURE control requests directed at an unconfigured endpoint causing request timeouts.

Split out endpoint and pipe stream functions into new EndpointStream.c/.h and PipeStream.c/.h files.

Indent core library function parameters so that there is only one parameter per line, to increase readability.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Added new ENDPOINT_*_BusSuspended error code to the Endpoint function, so that the stream functions early-abort if the bus is suspended before or during a transfer.

Fixed Set/Clear Feature requests directed to a non-configured endpoint not returning a stall to the host.

Make TeensyHID bootloader use an 8 byte control endpoint to match the official Teensy, just in case Paul decides to authenticate on that attribute in the future.

Fixed Endpoint_Write_Control_Stream_* functions not sending a terminating IN when the given data length is zero.

Update CDC Class Driver character stream functions to use the correct avr-libc return codes for errors and EOF.

Fix pointer arithmetic on void byte buffers by explicitly typecasting the buffer pointers to uint8_t* before altering them.

Moved USBtoSerial demo the Projects directory, as it is simply an expanded CDC demo. Added const qualifier to Endpoint/Pipe stream write routines.

Make Control Endpoint stream transfers more reliable by adding in early aborts for unexpected new SETUP tokens, or unexpected status stage during control stream writes.

Fix corruption in Device RNDIS demos TCP stack when too many connections attempted simultaneously, freezing the device when a page was re-fetched before the first connection was closed.

Fix incorrect model compatibility information in the Host LowLevel demo overview text files.

Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.

Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.

Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.

Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.

Added new EEPROM and FLASH buffer versions of the Endpoint and Pipe stream functions. Changed Endpoint.c and Pipe.c to use a templated system to build the seperate functions, rather than duplicating each function's code many times.
