The Visualization Manager PCM/FFT copy function was already observing
these parameters for null input and only returning output to the ones
which were not null. This just makes it clear that they are both
optional parameters. This is useful for future visualization adventures,
allowing PCM copy without invoking the FFT processing, or requesting FFT
without also having to keep the PCM.
This is mostly only a compile time change, and has no noticeable effect
on the current runtime behavior, as the only consumers of the Visualizer
data currently request both PCM and FFT.

This affects User Defaults, but only has any effect on ChunkLists which
are being used for conversion, and only if they're processing DSD source
material. Thus, the observer should only be added on the one stream that
is converting DSD, and should definitely be removed when the object is
deallocated.
This fixes a serious crash bug that mostly appears to only affect Intel
Macs, and has no major side effects on Apple Silicon that I can tell.
It's a good thing I still own an Intel Mac or two to test on, even if
they are both trapped on older releases of macOS.

Apparently I somehow didn't notice this situation because I still had
Rubber Band enabled, and existing users kept it enabled ever since I
introduced it.

Move this commonly used string decoding helper to the CogAudio framework
and import it in every plugin that uses it.

Apparently, stringWithUTF8String: just returns nil when the encoding is

The converter doesn't just require an output format call, it also
requires this input format change callback to actually signal it to
reopen the converter process with a new format setup.

Output format mostly requires stopping and restarting the output device,
and this also prevents us from using the latency function properly,
which apparently always returns 0 for output devices anyway. These
changes also prevent the output callback from hanging when resets occur.

Fixes visualization latency under virtual machines, at least. Not sure
which local or native systems would be reporting high latency here, but
this should fix them as well.

Move the DSPs to the output node, so they don't get closed and reopened
across each file. Also restructure the output handler to buffer a little
on its own, to account for track switch activity.

The filter uses a pre-buffer of input audio, so extrapolate from the
actual input to fill the buffer. Fixes clicking on non-zero-crossing
track endings.

Buffers were being treated as empty before they were actually processed,
due to races between the current node's end of stream marker and
actually feeding the output buffer.

This was attempting to retrieve the NSURL host object, possibly on a
file URL where the two did not match a previous check. Now we only pass
the full scheme/host/path check if both URLs are not file URLs.

There is a race condition with the next Node in the chain and the End of
Stream marker, considering how tiny the buffering is for these DSPs. Set
End of Stream instead after inserting the end of stream flush chunk.

DSPs should not be performing a cascading reset when resetting just
their own buffers, for example, on init or shutdown of just that one
DSP filter.

Cleaned up project settings to current defaults, except for the macOS
deployment version, which is still 10.13. Cleaned up a lot of headers
and such to include with angle braces instead of double quotes. Enabled
build sandbox in a lot of places. Disabled subproject signing in several
places, for libraries and frameworks which will be stripped and signed
when they are copied into place in the final build.
Also, while trying to solve compilation issues, the visualization
controller was reverted to the Objective C implementation, which is
probably faster anyway. Stupid Swift/Objective-C language mixing issues.

Seeking now mutes properly, and will not leave the audio muted across
other operations. Audio output changes should also mute and destroy the
