a884a419db gstreamer/buffer: Add a BufferCursor / BufferCursorRef helper structs 
This implements Read/Seek or Write/Seek and allows to read/write/seek
into the buffer without merging the memories inside.

The writer also only maps the memory write-only as compared to all other
ways of accessing the buffer/memory data in a writable way, which have
to map it read-write.

See https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/425
for a similar API proposal for GStreamer core.

2b70db3a9e gstreamer/buffer: Add BufferRef::peek_memory_mut() function 
This gives a mutable reference to the given memory and fails if the
memory is not actually writable.

9d5ae8ed14 gstreamer: Don't take mini objects by value for append() and similar operations 
Compared to
  let foo = Foo::bar(foo);
the new form is easier to follow
  foo.bar();

7230aee069 Switch everything from lazy_static to once_cell::Lazy 
Fewer macros, faster compile-time and the Lazy type will likely end up
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.

007f80ca32 buffer: Allow setting/unsetting buffer flags 
As there are extension flags types, we need separate setter/unsetter
functions for the flags, or otherwise we would always clear the
extension flags types (e.g. GstVideoBufferFlags).

3a8d05075d Switch everything from mem::uninitialized() to MaybeUninit or mem::zeroed() 
And also fix a few cases where mem::uninitialized() was simply wrong to
use.

6d5bded7b3 Get rid of lifetime for the Meta structs
