Remove driver files that generate compiler warnings from the RISC-V_Renode_Emulator_SoftConsole project.

Add references to third party page ref using newlib with FreeRTOS into the tasks.c file in each place newlib is referenced.
Move the position of the traceTASK_DELETE() trace macro in case of use with a memory allocator that writes over freed memory even when inside a critical section.
Efficiency improvement: Make sure xTaskIncrementTick() does not return pdTRUE when the scheduler is locked. This just prevents an unnecessary yield interrupt (unnecessary as it is ignored) when xYieldPending happens to be pdTRUE.

Nordic port. Notes for Richard -- the work items we discussed about for nrf52840-dk and Wiced_CY still remain. The only reason for this commit is we want to test out submodule.
Correct code comments that referred to taskYIELD_FROM_ISR to portYIELD_FROM_ISR.
Update RV32 port to use 16 byte-alignment all the time (only strictly necessary when using FLOP instructions).
sync from github to svn: this version of atomic.h does not have compiler specific symbols. compiler specific optimization is to be merged in each port/<compiler>/<arch> directory.
RISC-V port updates: The machine timer compare register can now be for any HART, and correct the sequence used to update the 64-bit machine timer compare register on 32-bit cores.

Tidy up Win32 port layer - include addition of new variable that prevents recursive attempts to obtain a mutex when the trace recorder is used inside an interrupt.
Remove the simple UDP client/server tasks from the MQTT demo as the demo's network connection can be tested more easily just by pinging it.
Tidy up the iot_config.h header files a little.
Remove IotMqtt_Assert( pTaskPool == IOT_SYSTEM_TASKPOOL ) from MQTT code
The cut down version of the task pool has only one task pool, namely,
system task pool. All the task pool API functions accept NULL as a
valid parameter for IotTaskPool_t and use the system task pool when
NULL is passed for the system task pool.
IOT_SYSTEM_TASKPOOL is defined to NULL to use system task pool and
therefore the above assert is no longer valid.
IotTaskPool_GetSystemTaskPool has been removed from the cut down version
of the task pool. define IOT_SYSTEM_TASKPOOL to NULL so that the MQTT library
builds successfully.
The DNS cache entry size was not big enough to fit the DNS name and
as a result the DNS reply parsing code returned error. Increased the
size of the entry to ensure that the DNS name can fit in.
Update the task pool demo to show re-use of recyclable jobs
The example now creates a recyclable job, schedules it and returns it
back to the task pool when it is done. It then again creates a
recyclable job and ensures that the task pool the same job present
it its cache.
Only partially implemented and may get reverted - updates to the Win32 port that uses a per-task event to prevent the task proceeding past its yield point if the SuspendThread() call used to stop the task does not take effect immediately. This is intended to fix issues reported by users, although we have been unable to replicate them ourselves.
Remove IotTaskPool_CreateRecyclableSystemJob() and IotTaskPool_ScheduleSystemJob() again, which were intended to be alternative APIs that only access the system task pool, and instead update IotTaskPool_CreateRecyclableJob() and IotTaskPool_ScheduleJob() to allow the parameter used to pass in the task pool handle to be NULL if the system task pool is the only one available.
Update the task pool demo app to include a lot more functionality.
Add link to dual core blog post into STM32H745I demo.
Doxygen corrections in list.h.
Use #error to check FreeRTOS.h is included before message_buffer.h and stream_buffer.h.
The macro taskRESET_READY_PRIORITY checks if the task being removed from the
ready list is the last one and only then resets the top ready priority
by calling portRESET_READY_PRIORITY. If we already know that it is the
last ready task being removed then there is no need to perform the check
again and the macro portRESET_READY_PRIORITY can be called directly. We were
doing the unnecessary check at two places and this commit fixes them.
This commit also increases the time period of check task to ensure that all
the demo tasks get a chance to run before the check is performed.
Use ARMCM33_DSP_FP_TZ_config.txt which comes with the MDS installation
We had a copy of ARMCM33_DSP_FP_TZ_config.txt file within the project directory
and it used to get outdated with each release of MDK because of non-backward
compatible changes in MDK. This change removes the copy in the project and
instead uses the one shipped with the MDK installation.
In small FreeRTOS applications it is unlikely there will be any task pools other than the system task pool. IotTaskPool_CreateRecyclableSystemJob() is therefore introduced to complement IotTaskPool_CreateRecyclableJob() that does not require the handle of the target task pool to be specified as a parameter. Likewise IotTaskPool_ScheduleSystemJob() is introduced to complement IotTaskPool_ScheduleJob() for the same reason.
IotTaskPool_CreateSystemTaskPool() calls synchronisation primitives, so cannot be called before the scheduler starts. Add a configASSERT() to ensure the scheduler is running when it executes.
IotTaskPool_CreateSystemTaskPool() can conceivably be called from multiple different libraries that depend on the thread pool. In this version _IotSystemTaskPool.running can be used to check the system task pool has not already been created. If the task pool has been created simply return from IotTaskPool_CreateSystemTaskPool() instead of re-creating it (which would leak memory and leave orphaned tasks).
Call taskENTER_CRITICAL() and taskEXIT_CRITICAL() directly in place of mapping them to TASKPOOL_ENTER_CRITICAL() and TASKPOOL_EXIT_CRITICAL() in the same file.
Rename _timerThread() _timerCallback(), as it is a callback function and not a thread.
