Implement the libdivecomputer API in Java and create C/JNI translation
layer.
[Dirk Hohndel: whitespace harmonization - yes, some of this is Java,
this still makes it much easier to read for me;
also changed the FTDI conditional compilation to make
sure we can still use that for mobile-on-desktop if
necessary]
