The changes include no longer leaving the workgroup for seeking or for
converter format changes, and also still leaving the workgroup on thread
termination if there was an error with intervals starting or finishing.

Long actions, such as file opening, playlist loading, metadata loading
and refreshing, etc, are now handled through NSProgress. Additionally,
a new status bar change displays the progress of the task instead of
the total duration of the playlist. Finally, app quit is blocked by a
running task, and if the app is quit while a task is running, it will
be delayed until the task completes, at which time the app will
terminate cleanly.

Prevent a race condition with deleting playlist entries while their
metadata is still being loaded by the player.

Guard Open in Finder against being called on a playlist with no
selection, which may happen if the action is triggered on an empty
playlist, which would cause an array out of bounds access error.

Guard the playlist entry retrieval function against being called on an

If there is somehow a legacy XML playlist, and there is no queue entry
in the plist, then it should not throw an exception from trying to add
a nil object to the return dictionary.

An impulse cache reduces any glitching from format channel count changes
to near insignificant levels, resulting in a more pleasant experience
when there are different mixed formats playing, or even a file which
changes format mid-playback.

Ensure that dynamic info updates, even on static files, only update the
exact track they apply to, by atomically assigning the userInfo property
before opening the decoder, so that callbacks to the player indicate the
correct track and don't assume it's the one that's currently visibly
playing. Fixes start of track metadata notifications from overwriting
the previously playing track.

String and art adder functions now perform type checks, in case of

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.

This condition would underflow when skipping a bunch of samples on the

As the decimator has shown to be twice as loud as it should be, the

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.
