Minor documentation fixes - change \note entries to \warning where appropriate and remove/update old documentation.

Enable -Wcast-align warning for the UC3 architecture in the ModuleTest build test now that the test passes with it.

Minor documentation improvements.

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

Don't validate the Device Descriptor's vendor ID when validating that a device is an Android Accessory device; the Product ID and (later) Accessory protocol support is enough to probe AOA class support without having to maintain a list of Android device manufacture VID values.

Altered the Mass Storage Host class driver so that SCSI data STALLs from the attached device can be recovered from automatically without having to reset the Mass Storage interface.

Altered the Mass Storage Host LowLevel demo so that SCSI data STALLs from the attached device can be recovered from automatically without having to reset the Mass Storage interface.

Convert the LowLevel AndroidAccessory demo to use the new class driver constants to reduce code duplication.

Add missing Doxygen documentation.

Add new Android Open Accessory class driver to the library core and add a new Android Open Accessory Host ClassDriver demo.

Move out Android Accessory Host demo to the Host mode LowLevel directory now that it is functionally complete.

Fix interface protocol match value for the Android Accessory Host demo interface configuration parser code (thanks to Opendous Inc.).

Add missing SVN eol-style property to ensure that source code line endings and converted to the native values on checkout.

Fix additional warnings under GCC 4.6.

Renamed USB_Host_ClearPipeStall() to USB_Host_ClearEndpointStall() as the function works on an endpoint address within the attached device, and not a Pipe within the host.

Updated MS_Host_ResetMSInterface() to now perform a full Mass Storage reset sequence to prevent data corruption in the event of a device lock up or timeout (thanks to David Lyons).

Add parenthesis around the library Endianness macros that do nothing on a particular architecture to prevent operator precedence issues depending on usage.

Minor documentation corrections.

Changed the reports in the GenericHID device demos to control the board LEDs, to reduce user confusion over the callback routines.

Fixed swapped TWI_ADDRESS_READ and TWI_ADDRESS_WRITE values.

Fixed TWI_ReadPacket() not releasing the TWI bus on read completion.

Set HOST_DEVICE_SETTLE_DELAY_MS to zero for the incomplete AndroidAccessoryHost demo to prevent a timeout on the Android device from aborting Accessory mode after a command it sent to switch modes (thanks to Opendous Inc).

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Replace blind interface descriptor search in the incomplete AndroidAccessoryHost demo with an intelligent search for the correct interface in the device matching the correct class/subclass/protocol values.

Updated all host mode demos and projects to use the EVENT_USB_Host_DeviceEnumerationComplete() event callback for device configuration instead of manual host state machine manipulations in the main application task.

Added new USB_Host_ConfigurationNumber global variable to indicate the selected configuration in an attached device.

Renamed global state variables that are specific to a certain USB mode to clearly indicate which mode the variable relates to, by changing the USB_* prefix to USB_Device_* or USB_Host_*.

Removed the HOST_STATE_WaitForDeviceRemoval and HOST_STATE_Suspended host state machine states, as these are no longer required.

Altered the USB_Host_SetDeviceConfiguration() function to update the new USB_Host_ConfigurationNumber global as required.

Moved out the Host mode standard request convenience/helper functions from the architecture specific Host driver files to the architecture agnostic HostStandardReq.c driver file.

Pull out Android Accessory Mode functions into a seperate set of files in the incomplete Android Accessory Mode Host demo. Improve Android Accessory Mode protocol support to correctly query the device's supported protocol and send the approriate device information strings.

Fix logic bug in the incomplete Android Accessory Host demo preventing correct detection of an attached Android Accessory Mode device.

Add new "checksource" target to the library makefiles, for automated source file existance checking.

Remove HID parser information output from the Low Level Host applications using the HID Report parser to simplify them, as this information can now be obtained using the new HIDReportViewer project when required.

Rename new Audio class driver functions, callbacks and events to ensure that they contain the USB mode (Device or Host) in the function names.

Ensure that only the requested Audio class pipes are mapped to endpoints within the device for a specific Audio Host Class driver instance.

Fix const-correctness of the Audio Host Class driver.

Correct errors in the existing Audio demo description files due to the new demo features (variable sampling rate vs. a fixed sampling rate).
