122ccafd1a gstreamer/gstreamer-app: Don't store strong references in futures Stream/Sink adapters 
This applies to the ones of the appsink, appsrc and bus. If we would
store a strong reference then they would keep alive the underlying
object forever even if their pipeline disappeared in the meantime.

Like this e.g. the bus stream would start returning None once the bus
was destroyed, similar to how other channels are working in Rust.

5479b23eb9 Use mem::ManuallyDrop instead of mem::forget() everywhere 
It makes the intentions clearer and potentially results in simpler
assembly, at least in debug builds.

8077b7ac82 Revert "gstreamer/log: Allow any glib::Object as target for logging" 
This reverts commit 67e6afc628.

Unfortunately this breaks the API due to how subclassing is modeled in
the GObject bindings.

4e30798ac7 Add #[must_use] attribute to mutex guards / stream lock

ed80467ff6 Make sure to hold MutexGuard for the remainder of the function in various places

and the lock to be released again immediately.

315a59e47d Allow changing bus sync handler and appsink/src callbacks when running with 1.16.3 or newer 
Previously it was not thread-safe to change them and could lead to
crashes but with 1.16.3 it is now.

Unsetting the bus sync handler before 1.16.3 will have no effect at all,
setting a new bus sync handler or appsink/src callbacks will panic.

41663f15ef bus: Don't use the bus sync handler in the bus Stream to notify about messages being available 
This is racy and can cause the consumer of the messages to never be
woken up anymore:

1. Waker is stored because no message on the bus
2. Sync handler is called, waker is woken up
3. Bus is polled again and no message is on it (yet),
   new waker is registered
4. Bus stores the message from 2. in its queue (after
   the sync handler has returned BusSyncReply::Pass)
5. No new message ever appears on the bus because all
   this happened for the very last message

struct with proper field names to make the code easier to understand.

b127f93cb9 bus: Take the mutex before popping messages for the bus stream 
Otherwise a message might arrive between popping, getting None and

2ba5105b80 Implement Sync/Send for more types and don't implement Send for TypeFind 
They can actually be shared with multiple threads at the same time
safely as all functions requiring an immutable reference are
thread-safe.

OTOH TypeFind can't be shared safely between different threads as not
all implementations of the TypeFind struct are thread-safe.
