Add a new API to control logging behavior, particularly for implementing
"log once" functionality and periodic logging. This helps avoid spamming
logs with repetitive messages.
The API provides:
- Static and dynamic context creation
- Configurable message identity calculation
- Periodic reset capability
- Context-aware logging macros
- Element message variants with context support

This adds "id" variants to most debugging functions, and allows providing a
string identifier instead of a GObject.
This allows providing unified and clearer debug logs for all the
non-gobject-based items, and opens the way for more unified logging.
As an extension, copying the object name is avoided as much as possible, by
using it directly instead of going through another copy.
* API : gst_debug_message_get_object_id

This takes a plain message string and not a format string, and as a
result doesn't have to be passed through vasprintf() and lead to further
unnecessary allocations. It can also contain literal `%` because of
that.
The new function is mostly useful for bindings that would have to pass a
full string to GStreamer anyway and would do formatting themselves with
language-specific functionality.
