Updates to make the FT4222 platform extender more usable.
Previous implementation opened libft4222.so and loaded symbols as
needed. This implementation removes dynamic loading of libft4222 in
favor of creating a new shared libary which links against libft4222.so.
The dynamic loading is now done in mraa.c. One C method is exposed in
libmraa-platform-ft4222.so for finding/initializing an FT4222:
mraa_platform_t mraa_usb_platform_extender(mraa_board_t* board);
Mraa.c attempts to open this platform library and calls the
mraa_usb_platform_extender method. If an ftdi4222 is connected, the
user gets added IO from the extender. If no FT4222 device is connected,
continue as normal.
* Create a new platform library for the FT4222
* Expose only 1 C method from the library -
mraa_usb_platform_extender
* libmraa-platform-ft4222.so contains CXX code (as well as previous
C code). All *allocs have been removed in favor of global
C++ stl containers.
* Previously, the FT4222 would only initialize correctly if 2 ftdi
devices existed. Now, initialize FT4222 devices based on the
device id.
* Many fixes for various problems with the FT4222
* Added unit test for platform extender (minimal functionality w/o hw)
* Updated to FindFtd4222.cmake module to handle standard arguments
* Removed CMAKE_C_FLAGS addition of -DFTDID2XX and -DFTDI4222 since
these are NOT used anywhere in source.
* Building the FTDI4222 shim requires libft4222.h which requires
ftd2xx.h. Updated CMakeLists.txt to require both when building
the shim.
