Kernel changes to improve power saving:
+ The timer task now blocks indefinitely if there are no timers active, allowing eTaskConfirmSleepModeStatus to return eNoTasksWaitingTimeout when configUSE_TIMERS is set to 1.
+ The next unblock time is calculated automatically after a task unblocks when waiting for a notification, allowing deep sleep to be entered earlier.
Change some data types in heap_4.c to allow it to be used on hardware that has 16-bit pointers without generating compiler warnings.
Add a small data model configuration to the MSP43FR5969 IAR demo.
Correct some code comments in the SAMA5D4 demo.
Rename /Demo/MSP430FR5969_LaunchPad to /Demo/MSP430X_MSP430FR5969_LaunchPad for consistency with other MSP430 demo directory names.
Fixed typos in comments repeated in multiple source files.
Update TimerDemo.c to test the new vTimerSetTimerID() function.
Update WinPCap NetworkInterface.c for FreeRTOS+UDP to correctly store a pointer to the network buffer structure at the beginning of the network buffer.
Add the errno definitions used by FreeRTOS+TCP and FreeRTOS+FAT into FreeRTOS's projdefs.h.
Remove redundant global definition vPortInstallFreeRTOSVectorTable from the GCC ARM_CA9 portASM.S file.
Ensure correct sequence of start up sequence when the Windows port is used on multi-core Windows machines by starting one thread in the suspended state.
Move initialisation of xNextTaskUnblockTime to the function that starts the scheduler, rather than from where the variable is declared - this fixes a compiler warning in newer IAR compilers.
