7663589d94 gstreamer: BusStream cleanup
A few small readability changes

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

b17f04e866 bus: Make bus Stream private and add functions on the bus directly for it
Also add a helper function that allows filtering the stream directly.

217bbc3e94 bus: Take the mutex before popping messages for the bus stream
Otherwise a message might arrive between popping, getting None and
locking the mutex for storing the waker. In that case we would never
be woken up.

cd56d60352 Bus::get_pollfd generate doc for both unix & windows
There are different implementations and signatures for `get_pollfd` depending
on whether the target platform is unix or windows. When generating the doc,
we need both implementations to appear regardless of the target platform. This
commit is inspired by the way Rust `std` library deals with `process::Command`
OS dependent variants
(https://doc.rust-lang.org/std/process/struct.Command.html#impl-CommandExt).

Documentation can't be accurate though as we can't use the`std::os::windows`
on `unix` and vice versa. As a workaround a fake fd class matching the other
platform is declared.

This could be further enhanced once `#[doc(cfg(...))]` is stabilized
(https://github.com/rust-lang/rust/issues/43781) by declaring `#[doc(cfg(unix))]`
or `#[doc(cfg(windows))]` instead of the hard coded comments `This is supported
on **Windows/Unix** only`. Unfortunately, these comments disappear when
generating will `--all-features` because they are not part of the documentation
in the gir file.
