Add vTaskGetTaskInfo() function that allows a TaskStatus_t structure to be returned for an individual task (previously information could only be obtained for all the tasks at once).
Add a member to the TaskStatus_t structure that is used to return the base address of the stack used by the task being queried.
Add xTaskGetTaskHandle() that allows the handle of a task to be looked up from the task's text name.
Continue to document the macros that allow RTOS objects to be created using statically allocated memory.
Introduced vApplicationDaemonTaskStartupHook(), which allows initialisation that that needs to be executed after the scheduler has been started to be executed from the RTOS daemon task.
Call prvResetNextTaskUnblockTime() in xTaskResumeAll() if a task is moved from the pending ready list - this can prevent an unnecessary wake from sleep mode if a task is unblocked by an interrupt while in a low power tickless state.
