Derivatives of Core::Object should be constructed through
ClassName::construct(), to avoid handling ref-counted objects with
refcount zero. Fixing the visibility means that misuses like this are
more difficult.
This commit is separate from the other Applications/Libraries changes
because it required additional adaption of the code. Note that the old
code did precisely what these changes try to prevent: Create and handle
a ref-counted object with a refcount of zero.
SonarCloud flagged this as m_delay_buffer is technically uninitialized
at the point at which the POD types are initialized in a constructor.
I don't check to see if this was actually a real issue, as the member
is ultimately unused. So lets just get rid of it.
