d991bb10ca add 'available' interface to the AudioBackendInfo
If a backend can be loaded, it does not mean that it can be used;
e.g. weak-linked jack-backend if libjack is not available.

3d12a4da82 fix deep obscure problem with loading multiple backends on OS X
all backends export a symbol declared as "extern "C" ARDOURBACKEND_API ARDOUR::AudioBackendInfo* descriptor ()".
dlopen'ing the backend apparently pushes the symbol "descriptor" into the single flat global namespace that we use
to be like other unix-like systems. this means that if a backend calls its OWN function named "descriptor", it
is indeterminate which one it will be, since the symbol will refer to the function first loaded by the runtime
linker. If the backend is not the first one discovered, this call to its own "descriptor" function will invoke
the function defined by another backend, even though these are supposed to have local scope only according
to our arguments to dlopen().

This fix doesn't try to fix the linker or namespace - it just makes sure that the WavesAudio backend doesn't
invoke its own descriptor() function, which it never really needed to do anyway.

8a6762f189 Revert "update wavesaudio backend, now supports Windows (ASIO) as well as OS X (CoreAudio)"
This reverts commit f374ce69a6.

The code does not compile on OS X, and includes changes to ARDOUR::AudioEngine
that have not landed in git.
