b21f576430 Add #[must_use] attribute to mutex guards / stream lock
It's usually a mistake if creating one of these and immediately dropping
them again as that would immediately unlock the mutex again.

98ecef7153 Make sure to hold MutexGuard for the remainder of the function in various places
Not assigning it to a variable would cause it to be dropped immediately
and the lock to be released again immediately.

71497e77de gstreamer/log: Allow any glib::Object as target for logging
gst::Object is not actually required. For plain glib::Objects only the
pointer address is printed instead of a name but it works fine.

d58cf01e3a 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.

This partially reverts 2f88dc6576

2f88dc6576 Only allow setting Bus sync handler and AppSrc/Sink callbacks once
Re-setting them is not thread-safe and can cause segfaults or worse.

cddccf9502 gstreamer/promise: Add Future constructor for Promise
This returns a tuple that basically works like a oneshot channel: the
Promise acts as the "sender" and once the promise resolves the
"receiver" contains the result.

fe4f074e90 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

63a8afafa5 gstreamer: Use more accurate types for Seqnum, GroupId and MetaSeqnum
For the latter introduce an actual opaque type that allows using them
for comparison purposes but is not just a plain u64.

For the former represent them as opaque type around an NonZeroU32. 0 is
the invalid case and does not happen in the majority of functions. Where
it can happen, represent this case by using an Option<_> instead.

This makes it harder to mis-use these types.

7230aee069 Switch everything from lazy_static to once_cell::Lazy

in the standard library in a similar form to this.

d3c77f400d Don't derive Debug impls for generic types where the type parameters don't have to impl Debug themselves
This allows to use MappedBuffer and similar types to be properly
debug-printed.

Also change VideoFrame/VideoFrameRef/RTPBuffer from a tuple struct to a
struct with proper field names to make the code easier to understand.

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.

It might be gone once we called into the parent class' implementation so
we need to keep a strong reference around here. Also we need to ensure
that we don't accidentally steal a floating reference from the caller
here: if the element is still floating it is apparently not part of this
bin and we can directly return FALSE.

dc7937a8d4 Don't leak missing Safety doc clippy warnings
With rustc 1.40.0, clippy checks that the `unsafe` functions come with
a `Safety` section. When running clippy on a downstream crate, the
macros such as `gst_plugin_define!` leak the clippy warnings for the
unsafe functions.
