15ccdea8b3 avfilter/vf_dedot: Fix leak of AVFrame if making it writable fails 
Even in this scenario, the frame still contains references to data that
won't be freed if the frame isn't unreferenced. And the AVFrame itself
will leak, too.

Fixes Coverity issue #1441422.

126cd3821d avfilter/vf_paletteuse: Fix potential double-free of AVFrame 
apply_palette() would free an AVFrame given to it only via an AVFrame *
(and not via AVFrame **) in three of its four exists (namely in the
normal path and in two error paths). So upon error the caller has no way
to know whether the frame has already been freed or not;
load_apply_palette(), the only caller, opted to free the frame in this
scenario.

This commit changes this by making apply_palette not freeing the frame
at all, which is left to load_apply_palette().

Fixes Coverity issue #1452434.

2980fb5704 avfilter/vf_unsharp: Don't dereference NULL 
The unsharp filter uses an array of arrays of uint32_t, each of which is
separately allocated. These arrays also need to freed separately; but
before doing so, one needs to check whether the array of arrays has
actually been allocated, otherwise one would dereference a NULL pointer.
This fixes #8408.

Furthermore, the array of arrays needs to be zero-initialized so that
no uninitialized pointer will be freed in case an allocation of one of
the individual arrays fails.
