Added new USB_DeviceState variable to keep track of the current Device mode USB state.

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.

  *  On the smaller USB AVRs, the USB controller lacks VBUS events to determine the physical connection state of the USB bus to a host. In lieu of

  *  slightly inaccurate due to the possibility of the host suspending the bus while the device is still connected. If accurate connection status is

  *    - The "Dynamic Memory Block Allocator" has been removed, as it was unused in (and unrelated to) the LUFA library and never

  *      used in user applications. The library is available from the author's website for those wishing to still use it in their

  *      applications.

+ *    - The USB_IsConnected global has been removed, as it is too vague for general use. Test \ref USB_DeviceState or \ref USB_HostState

+ *      explicitly to ensure the device is in the desired state instead.

  *  <b>Host Mode</b>

  *    - The HIDParser.c module has moved from LUFA/Drivers/USB/Class/ to LUFA/Drivers/USB/Class/Host/.

- *    - The USB_GetDeviceConfigDescriptor() function now requires the desired configuration index within the device as its first

+ *    - The \ref USB_GetDeviceConfigDescriptor() function now requires the desired configuration index within the device as its first

  *      parameter, to add support for multi-configuration devices. Existing code should use a configuration index of 1 to indicate the

  *      first configuration descriptor within the device.

+ *    - The non-standard "Ready" host state has been removed. Existing \ref HOST_STATE_Configured code should be moved to the end of

+ *      the existing \ref HOST_STATE_Addressed state, and the existing HOST_STATE_Ready state code should be moved to the \ref HOST_STATE_Configured

+ *      state.

  *  <b>Device Mode</b>

  *    - The \ref CALLBACK_USB_GetDescriptor() function now takes an extra parameter to specify the descriptor's memory space so that

  *      descriptors in mixed memory spaces can be used. The previous functionality can be returned by defining the USE_FLASH_DESCRIPTORS

  *      token in the project makefile to fix all descriptors into FLASH space and remove the extra function parameter.

+ *    - Removed USB_IsSuspended - test \ref USB_DeviceState against \ref DEVICE_STATE_Suspended instead.
