libav: expose fake booleans properties as enums
...
Some ffmpeg options claims to be booleans but are actually 3-values enums
with -1 as default instead of 1 or 0. Handle those using a custom enum
so we keep the same defaults as ffmpeg and users can properly configure them
if they need to.
See https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/3035
for an actual example of this problem. The GStreamer element was
automatically enabling a non-default option, leading to strange behavior
in the AAC encoder.
Fix #3035

avcfg: Don't leak the support GArray when registering flag/enums
...
* Only create it if we are attempting to put values in it
* If we sucessfully registered the values, only free the GArray
* IF we didn't, also free the backing memory

libav: avcfg: Avoid brittle comparision
...
Subtracting a gint from another (or a guint from another) has no guarantees that
it will result in a gint.
Therefore do the actual comparision instead.
Also use the *actual* type for comparing flags (the field value types are different)

libav: avcfg: Don't leak duplicate enumvalue entries
...
If we discard the duplicates, we also need to free the allocated strings.

libav: Fix for APNG encoder property registration
...
The AVClass name of Animated PNG in FFmpeg 5.x is "(A)PNG"
and it will be converted to "-a-png" through
g_ascii_strdown() and g_strcanon(). But GLib disallow leading '-'
character for a GType name. Strip leading '-' to workaround it.
