640a65bf96 gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

a7c2aa473f vulkan/image: don't rely on weak-ref notifies for views
Weak refs don't quite work here correctly as there is always a race with
taking the lock between find_view() and remove_view().  If find_view()
returns a view that is going to removed by remove_view() then we have an
interesting situation.

In theory, the number and type of views for an image are relatively
constant and should not change one they've been set up which means that
it is actually practical to perform pool-like reference counting here
where the image holds a pool of different views that it can give out
as necessary.
