apps/graphics/ft80x:  Add interfaces to control the backlight.  apps/examples/ft80x:  Fade the display on and off between each example.

apps/graphics/ft80x:  Add capabilitilies to send commands to the co-processor outside of the context of a display list.  apps/examples/ft80x:  Add another copressor example.. spinner animation.

apps/graphics/ft80x:  Add routine to wait for logo animation to complete.  apps/examples/ft80x:  Add more graphic demonstrations.

apps/graphics/ft80x:  Add support for reading/writing multiple registers.  Add interface to obtain the touchscreen transform matrix.  apps/examples/ft80x:  Add more co-processor demos.

    apps/examples/ft80x:  Add another co-processor demo
    ft80x: Add a few more debug message.

    apps/graphics/ft80x:  Replace polling logic with gentler signal logic when waitinf for the CMD FIFO to become empty.
    apps/examples/ft80x:  Add first co-processor example.
    apps/graphics:  Extend library to manage display lists either in display memory (RAM DL) or provided directly to th co-processor FIFO (RAM CMD).
    apps/examples/ft80x:  Some minor clean-up.  Trivial changes for coprocessor support.

apps/graphics/ft80x and apps/examples/ft80x:  Fix a few compile-relate issues introduced with last merge.

    apps/graphics/ft80x:  Add support for accessing graphics ram.  apps/examples/ft80x:  Add more primitive graphics demos.
    apps/examples/ft80x:  Add a couple more demos of primitives.  Use new ft80x_dl_create() to simplify.
    apps/graphics/ft80x:  Add ft80x_dl_create() which simplies writing of very simple display lists.

    apps/examples/ft80x:  Add one display example.  Many more are needed but this is enough to get started with testing (when I eventually have hardware).
    apps/examples/ft80x:  Add the bare framework for a test of the FT80x

apps/graphics/ft80x:  Add the beginning of FT80x support library.  So far consists only of some display list helpers.

apps/nshlib:  Fix compile error when CONFIG_NSH_DISABLESCRIPT is not defined.  The field np_flags does not exist if scripting is disabled.

system/stackmonitor:  Re-design the stack monitor so that it does not make forbidden calls directly into the OS, breaking the portable POSIX OS interface.  It now properly uses the PROCFS file system to glean information about stack usage.

Fix documentation mistake about standalone problem

I guess author meant "standalone program" not "standalone problem" ?

Then, it was replicated elsewhere in code base,
and fixed accordingly with this patch.
