Update audio/chromaprint to 1.4.2

• Chromaprint itself is now licensed MIT, but it still includes LGPL21 code
• Add DOXYGEN option to build and install API docs
• Add TEST option to build regression tests
• API has changed, so some dependent ports needed to be patched (mostly taken from their respective upstream repositories)
