unix/main: When preparing sys.path, allocate exact strings on uPy heap.
...
Due to the way modern compilers work (allocating space for stack vars once
at tha start of function, and deallocating once on exit from), using
intermediate stack buffer of big size caused blockage of 4K (PATH_MAX)
on stack for the entire duration of MicroPython execution.

cc3200: Shrink the FreeRTOS heap and place TCB+stack in freed location.
...
The 16k FreeRTOS heap originally had all TCBs and stacks dynamically
allocated within it (plus semaphores and some other things). Now that
xTaskCreateStatic is used instead of xTaskCreate, the TCBs and stacks
are allocated statically and no longer use any of the FreeRTOS heap.
Therefore, the FreeRTOS stack can be shrunk by the amount that has been
made static. Furthermore, the TCBs and stack that are now static should
be placed in the .rtos_heaps section of RAM because this RAM is treated
specially by the bootloader (the bootloader executes from the first 16k
of RAM and loads the firmware into the section starting after the 16k).
After this patch the FreeRTOS heap (ucHeap) is 7200 bytes. The memory
available for the MicroPython heap is 54936 bytes (including GC overhead).

cc3200: Start the simplelink spawn task using the static task creator.
...
In VStartSimpleLinkSpawnTask we change xTaskCreate to xTaskCreateStatic
so that the task is created using statically allocated memory for the TCB
and stack.
This means that xTaskCreate function is no longer needed (the static
version is now used exclusively).
