Create Zynq demo using the latest Vitis tools (#746)

Browse Source 
* Add hello world project for Vitis.

* Working hello world program.

* Remove the call to ps7_init().

* Demo moved from the XSDK project to Vitis is now compiling - not tried running yet though.

* Blink is printing out in blinky demo.

* Adjust the priorities of the demo tasks to enable them to run at once.
Update blocktim.c so it stores the line on which an error was detected in the error occurred variable rather than just setting the variable to true.

* Add launch configuration file.
Remove unused definitions from FreeRTOSConfig.h.
Edit the comments that describe what the demo does.

* Revert changes to blocktim.c, which should have been in a separate PR.

* Correct header comments in new files.

* Update headers for core checks.

* Third attempt at getting headers through the commit checks - copy headers from other files is not enough.

* Still trying to get core checks to pass.

* Update lexicon.txt

* Correct spelling in Cortex-A9 QEMU main.c.

* The FreeRTOS Cortex-A port implements a full interrupt nesting model.
*
* Interrupts that are assigned a priority at or below
* configMAX_API_CALL_INTERRUPT_PRIORITY (which counter-intuitively in the ARM
* generic interrupt controller [GIC] means a priority that has a numerical
* value above configMAX_API_CALL_INTERRUPT_PRIORITY) can call FreeRTOS safe API
* functions and will nest.
*
* Interrupts that are assigned a priority above
* configMAX_API_CALL_INTERRUPT_PRIORITY (which in the GIC means a numerical
* value below configMAX_API_CALL_INTERRUPT_PRIORITY) cannot call any FreeRTOS
* API functions, will nest, and will not be masked by FreeRTOS critical
* sections (although it is necessary for interrupts to be globally disabled
* extremely briefly as the interrupt mask is updated in the GIC).
*
* FreeRTOS functions that can be called from an interrupt are those that end in
* "FromISR". FreeRTOS maintains a separate interrupt safe API to enable
* interrupt entry to be shorter, faster, simpler and smaller.
*
* The Zynq implements 256 unique interrupt priorities. For the purpose of
* setting configMAX_API_CALL_INTERRUPT_PRIORITY 255 represents the lowest
* priority.

/******************************************************************************
* NOTE 1: This project provides two demo applications. A simple blinky
* style project and a more comprehensive test and demo application. The
* mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to
* select between the three. See the notes on using
* mainCREATE_SIMPLE_BLINKY_DEMO_ONLY in main.c. This file implements the
* simply blinky style version.
*
* NOTE 2: This file only contains the source code that is specific to the
* basic demo. Generic functions, such FreeRTOS hook functions, and functions
* required to configure the hardware are defined in main.c.
******************************************************************************
*
* Set configUSING_QEMU to 1 in FreeRTOS.org to have the demo output to the
* QEMU UART. Not simulated time is much slower than calendar time when using
* QEMU, so three seconds of simulated time is a lot longer than three seconds
* of emulated time.
*
* main_blinky() creates one queue, and two tasks. It then starts the
* scheduler.
*
* The Queue Send Task:
* The queue send task is implemented by the prvQueueSendTask() function in
* this file. prvQueueSendTask() sits in a loop that causes it to repeatedly
* block for 200 milliseconds, before sending the value 100 to the queue that
* was created within main_blinky(). Once the value is sent, the task loops
* back around to block for another 200 milliseconds...and so on.
*
* The Queue Receive Task:
* The queue receive task is implemented by the prvQueueReceiveTask() function
* in this file. prvQueueReceiveTask() sits in a loop where it repeatedly
* blocks on attempts to read data from the queue that was created within
* main_blinky(). When data is received, the task checks the value of the
* data, and if the value equals the expected 100, toggles an LED (writes "blink"
* to the UART when using QEMU). The 'block time' parameter passed to the queue
* receive function specifies that the task should be held in the Blocked state
* indefinitely to wait for data to be available on the queue. The queue
* receive task will only leave the Blocked state when the queue send task
* writes to the queue. As the queue send task writes to the queue every 200
* milliseconds, the queue receive task leaves the Blocked state every 200
* milliseconds, and therefore toggles the LED (or writes "blink" to the UART)
* every 200 milliseconds. Note when using QEMU the emulated 200ms is much
* longer than a real 200ms of calendar time.

BASIC INTERRUPT DRIVEN SERIAL PORT DRIVER.
Note1: This driver is used specifically to provide an interface to the
FreeRTOS+CLI command interpreter. It is *not* intended to be a generic
serial port driver. Nor is it intended to be used as an example of an
efficient implementation. In particular, a queue is used to buffer
received characters, which is fine in this case as key presses arrive
slowly, but a DMA and/or RAM buffer should be used in place of the queue in
applications that expect higher throughput.
Note2: This driver does not attempt to handle UART errors.

* See http://www.freertos.org/RTOS-Xilinx-Zynq-QEMU.html for instructions.
*
* This project provides two demo applications. A simple blinky style
* project and a more comprehensive test and demo application.
* The mainCREATE_SIMPLY_BLINKY_DEMO_ONLY setting (defined in this file) is used to
* select between the two. The simply blinky demo is implemented and
* described in main_blinky.c. The more comprehensive test and demo application
* is implemented and described in main_full.c.
*
* This file implements the code that is not demo specific, including the
* hardware setup and FreeRTOS hook functions.
*
* !!! IMPORTANT NOTE !!!
* The GCC libraries that ship with the Xilinx SDK make use of the floating
* point registers. To avoid this causing corruption it is necessary to avoid
* their use unless a task has been given a floating point context. See
* http://www.freertos.org/Using-FreeRTOS-on-Cortex-A-Embedded-Processors.html
* for information on how to give a task a floating point context, and how to
* handle floating point operations in interrupts. As this demo does not give
* all tasks a floating point context main.c contains very basic C
* implementations of the standard C library functions memset(), memcpy() and
* memcmp(), which are are used by FreeRTOS itself. Defining these functions in
* the project prevents the linker pulling them in from the library. Any other
* standard C library functions that are used by the application must likewise
* be defined in C.
*
* ENSURE TO READ THE DOCUMENTATION PAGE FOR THIS PORT AND DEMO APPLICATION ON
* THE http://www.FreeRTOS.org WEB SITE FOR FULL INFORMATION ON USING THIS DEMO
* APPLICATION, AND ITS ASSOCIATE FreeRTOS ARCHITECTURE PORT!
