Fixed incorrect call to the user callback CALLBACK_Audio_Device_GetSetInterfaceProperty() in the Audio Class device driver (thanks to Tiit Ratsep).

Audio Device Class driver changed to also require the index of the Audio Control interface within the device, for SET/GET/CUR/MIN/MAX/RES property adjustments.

Added Dataflash operational checks and aborts to all projects using the Dataflash to ensure it is working correctly before use.

Update maintenance scripts to add targets to validate the current branch for complete correctness. Add maintenance script target for checking for release suitability.

Prevent the first maintenance script rule from running if no target is specified to the maintenance script.

Fixed compile error for the UC3 architecture when INTERRUPT_CONTROL_ENDPOINT is specified (thanks to Andrus Aaslaid).

Raised the guard bits in the AVRISP-MKII clone project when in PDI and TPI to 32, to prevent communication errors on low quality connections to a target.

Update code and StaticAnlysisTest so that missingInclude warnings do not have to be suppressed, and so that all code except for third party libraries can be checked.

Update SingleUSBModeTest makefile to separate out the messages from the test commands.

Update ModuleTest to compile for each sub-family within each architecture, to ensure that the code compiles for all devices (not just for one device in each architecture).

Update StaticAnalysisTest to check for missing header files. Fix found incorrect header file paths in the demos and projects.

Fixed possible enumeration error if the user application selects the non-Control pipe between the Powered and Default states of the host state machine.

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.

Fix errors uncovered by the new build test compile warnings; fix UC3 pipe configuration function broken, redundant function prototypes and unused parameters.
