In preparation to make a more specialized VideoFrameGL this extracts
common helper functions valid for all VideoFrames into a trait that can
be implemented without too much code duplication.
Note that this is a breaking change, now VideoFrame and VideoFrameRef
cannot really be used without include the gst_video prelude.

When I introduced the 'ser_de' feature, I couldn't find a way to
name it 'serde' while also make it pull the optional 'serde'
crate together with the other related dependencies.
With rustc >= 1.60 we can use 'dep:serde' to refer to the 'serde'
dependency as part of the 'serde' feature.
Represents combinations of flags with a '+' separated string of nicks,
or an empty string for no flags set.
Note that most flag types will ignore any flags using multiple bits when
serializing, since in most cases these flags cover all used bits.
And also allow implement serialization with serde (behind a feature) to
allow sending navigation event through the network (for example from a
browser with a WebRTC data channel).
For cleanliness the prelude module only needs to reexport preludes from
direct, "top-most" crates, which themselves take care of reexporting
preludes from its dependencies again. This shaves off some code while
maintaining the same set of exports.
In gir it was brought up [1] that some traits (in particular
`*ExtManual`) are exported from the crate root in addition to the
prelude, cluttering the environment unnecessarily. This commit removes
all these reexports, leaving those in prelude (that were already there)
only.
After this commit everything matching `Ext(Manual)?\b` in `lib.rs` sits
within `pub mod prelude {};`.

gir has been fixed to omit all unnecessary imports from objects, enums
and flags which currently are the only offenders of this linter warning.
Hence disallow this warning from now on which is anyway not applied to
every crate - like gstreamer-gl - where such issues have been uncovered.
Capitalization is wrong in function and parameter/variable names:

The next version of gir is going to generate doc(cfg()) attributes on
many symbols to show feature-dependence hints. While autogenerated sys
crates get this attribute in their own (generated) lib.rs file the safe
wrapper crates do not have such an autogenerated lib.rs file.
