Second attempt at SPI::DMATransfer. Now uses separate tx and rx buffers, and I also added code to wait for tx to complete and SPI to not be busy before exiting the function. Note. Operation of rx buffer has not been tested

Added first pas at SPI::DMATransfer(byte *buf, int length) - and updated ILI9341 lib to use DMA Transfer for fill rect

Added old Adafruit_ILI9341 lib, and modified the STM version of the lib so that the class name matches the filename for adafruit_ILI9341_STM

Renamed libraries, but using original function names.
...
This way one knows if he is using the old or STM library by looking at
the include line, while the sketch should compile file as the functions
are named the same. I believe this is the best compromise.

These are the DMA ILI9341 library and Extra fonts GFX
...
Added DMA support for STM32F1xx, and extra check in line and rect
funtions to avoid trying to draw a 0 width or 0 height line/rectangle,
which would cause 0 bytes DMA transmission and hang in a loop.

Speed improvements to ILI9341 library (between 25% and 58% faster depending on which function is being called

Added modified version of AdaFruit_ILI9341 library, based on work by Matthias (@madias on the Arduino forum). Also includes a small speed optimization to call nonstandard spi::write(byte) function, as this gives around 20% speed improvement. Note SPI clock rate, chosen my @madias, of DIV_2 is 36Mhz, which exceeds the publish maximum spi clock of 10Mhz, however it seems to work with most devices
