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.

b4cf5e279b fix dup free in waves/midi:
The PortMidi queue just holds a pointer to the midi events.
The same Midi events are free()d during WavesMidiBuffer::clear()
which is called at cycle start for every buffer and in the dtor
of the WavesMidiBuffer.

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.

b1da9af8de ALSA|Dummy: ignore port unregistration when engine is stopped
When changing Engine parameters, ardour first stops
the engine and only later when re-etablishing ports
unregisters/re-registers them.

ALSA: silently ignore port unregs and silently accept registrations
Dummy: print a PBD::info message,

dc318e6e74 ALSA|Dummy Backend: do as jack does:
when the backend is closed, unregister all ports.

6408d90258 fix waf thinko in backends wscript 2014-09-03 18:44:34 -04:00
65715dd298 Make sure all our VC projects agree that the product is called 'Mixbus3' (as opposed to just 'Mixbus')
It'd be nice if we could use 'ARDOUR::config_dir_name' for this purpose (or perhaps 'PROGRAM_VERSION'). However, neither is implemented widely enough at present to make this practical. Keep an eye on them though, as possible future strategies.
