added c2hal
This is a transpiler which converts C headers to .hal files. Its design
is intended to mirror hidl-gen in order to make it easier for team
members familiar with one to be familiar with the other.
After making c2hal, commands from ~/android/master/:
Build the test.h header:
c2hal -r android.hardware:hardware/interfaces -p android.hardware.baz@1.0 system/tools/hidl/c2hal/test/test.h
Build the simple.h header:
c2hal -r android.hardware:hardware/interfaces -p android.hardware.simple@1.0 system/tools/hidl/c2hal/test/simple.h
Build all headers from libhardware:
python3 system/tools/hidl/c2hal/test/build_all.py ~/android/master/hardware/libhardware/include/hardware/
Build various OpenGl versions:
python3 system/tools/hidl/c2hal/test/build_all.py -g ~/android/master/frameworks/native/opengl/include/EGL/
python3 system/tools/hidl/c2hal/test/build_all.py -g ~/android/master/frameworks/native/opengl/include/ETC1/
python3 system/tools/hidl/c2hal/test/build_all.py -g ~/android/master/frameworks/native/opengl/include/GLES/
python3 system/tools/hidl/c2hal/test/build_all.py -g ~/android/master/frameworks/native/opengl/include/GLES2/
python3 system/tools/hidl/c2hal/test/build_all.py -g ~/android/master/frameworks/native/opengl/include/GLES3/
python3 system/tools/hidl/c2hal/test/build_all.py -g ~/android/master/frameworks/native/opengl/include/KHR/
