The two toolbars seem to require unique identifiers for each of their
items, even when they're separate toolbars in separate windows.

Now read all metadata and signal it, and also support pre-buffering
a small block of sample frames if there is embedded artwork, since the
embedded artwork must be handled by the sample decode function.

DFT should use aligned memory blocks for best results. Also allocate one
extra sample for DFT output, just in case DFT zop is as bad as zrop.

Work back to a vDSP implementation, this time using overlap-save instead
of overlap-add, also accumulating the results as complex values, only
inversing them once at the end, and finally, replacing the FFT method
with the newer DFT API.

String and art adder functions now perform type checks, in case of
memory errors that somehow result in classes changing type. Which in
itself is a strange thing to happen.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
Restructure the add string or art functions so they don't take a pointer
to a pointer, which may have caused issues when receiving a nil string
from the caller. Instead, take a plain pointer, and return the object,
returning the ID of the object to a pointer to an int64_t.
Also change several prototypes and functions to use _Nonnull or
_Nullable where appropriate.

The properties function should not be dereferencing an invalid index
into the layer codec name array if layer is not set to 1 through 3. This
could happen if, for instance, an MP3 file has an invalid ID3v2 tag.

This condition would underflow when skipping a bunch of samples on the
start of playback, or otherwise seeking, and could cause an unsigned
underflow, which would cause the subsequent vDSP_vflt32 to overread into
the MAD sample buffer and crash.

As the decimator has shown to be twice as loud as it should be, the
volume should be reduced by half when converting DSD to PCM with it.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
Pure downsampling is slower, but may or may not be more accurate. Though
probably not worth it. It did help me realize a minor error, though.
The decimator's volume is twice as loud as it should be.

This prevents crashes where inputs were not returning either properties
or metadata blocks and the file open cache was attempting to cache the
resulting nil pointer as if it were valid. Also prevent the metadata
redundant string coalescing from processing nil objects as well, in case
it's used that way somewhere else.

Submodule projects are sometimes out of my control, so I shouldn't have
to deal with team identifiers in projects that don't affect my build

to fork and modify every project I touch that contains this stuff. No.

Set baseline real-time priority for audio threads even on old macOS,
since that API is available there. Only set it once, and do not attempt
again if it fails, only once per thread.

I'm not sure about macOS Ventura, but stable releases of macOS, at
least on Intel, require that threads joining Audio Interval
workgroups already be set to run as real-time before joining. Not
doing this results in an uncaught exception and a crash.
