446bb7ec3e examples/tutorials: fix macOS run() wrapper terminating too early
Using terminate() kills the whole process instead of just stopping the event loop, so we're back to the 'old' way.
However, if the provided function finishes too early, that can also fail (will call stop() on a not-yet-running NSApp).
Creating a delegate and waiting for the callback makes sure NSApp is running before the actual main() is called.

Also, for whatever reason only tutorials were changed to use terminate(). Now both tutorials and examples are
using identical code.

fc4a0d29c6 tutorials: Use async-channel instead of the glib MainContext channel
The latter will be removed in favour of using async code in the future,
and async code generally allows for more flexible message handling than the
callback based MainContext channel.

9453d63631 gst/pad: [Ghost]PadBuilder: inherit name from template or target when possible
This commit adds convenience auto naming in the following cases:

* When building from a non wildcard-named template, the name of the template is
  automatically assigned to the Pad. User can override with a specific name by
  calling `name()` on the `PadBuilder`.
* When building with a target and no name was provided via the above, the
  GhostPad is named after the target.

e026d922e4 gstreamr: bus: Add BusWatchGuard to automatically remove watch
Previously, with add_watch()/add_watch_local() you had to remember
calling remove_watch() in order not to leak the bus, the watch source
and two associated file descriptors. Now these methods instead return an
object of type BusWatchGuard that will automatically remove the bus
watch when the object is dropped.

003554876c Update various APIs to use glib::GStr
Currently only covers what is needed to keep code compiling, plus
everything caps/structure/tags related.

This avoids unnecessary heap allocations for adding the NUL-terminator
of C strings, and especially makes caps/structure handling as efficient
as in C.

e579eb5d84 examples/tutorials: Use NSApp terminate() instead of sending an event
Has the same effect while being much more concise.

function, so objc::msg_send! had to be used directly.

57d8d46ab6 gst/format: fix some ops and add others
Some operations were implemented on types that wouldn't result in
the expected physical unit. E.g.:

- `ClockTime / ClockTime` results in a unit-less factor.
- `u64 / ClockTime` would result in a `1 / ClockTime`. Since we don't
  use any `Frequency` type, this operation is removed. Users should
  use the `ClockTime` accessors to compute the expected value.

This commit also adds:

- multiplications with integers as the left hand side operands.
- `Partial{Eq,Ord} for `Signed<T>` with `T` as left hand side operand.
- `opt_add` / `opt_sub` for `Signed<T>` with `T` as left or right hand
   side operands.
- missing tests for `Partial{Eq,Ord}` and `OptionOrd`.

This implementation can interfere with unrelated code and was removed:

- `Signed<usize>.` `PartialOrd` makes existing code computing the len
  of slices needing type annotation because the len is later used in
  a comparison for which the compiler is unable to determine if
  the len is `Signed<usize>` or `usize`.
