avformat/rtsp: initialize reply1 
It seems reply1 is initialized by ff_rtsp_send_cmd() in most cases but there
are code paths like "continue" which look like they could skip it but even if not
writing this so a complex loop after several layers of calls initialized a local
variable through a pointer is just bad design.
This patch simply initialized the variable.

30475c95ba lavc/h264dsp: R-V V 8-bit h264_idct_add16 
While this *tends* to be faster than plain C, the performance numbers
are all over the place, presuambly due to the conditional character of
the main loop.

Some additional micro-optimisations should be feasible after the
underlying h264_idct_add and h264_idct_dc_add functions are also
implemented. Then it will no longer be necesseray to stricly abide by
the C ABI.

cd9ceaef22 avutil/hwcontext_videotoolbox: Set CVBuffer CGColorSpace 
In addition to the other properties, try to obtain the right
CGColorSpace and set it as well, else it could lead to a CVBuffer
tagged as BT.2020 but with a CGColorSpace indicating BT.709.

Therefore it is essential for consistency to set a colorspace
according to the other values, or if none can be obtained (for example
because the other values are all unspecified) unset it as well.

Fix #10884

b4f9fcc63c avutil/hwcontext_videotoolbox: Update documentation 
The documentation was not clear at all what specifically the
function does, so it was left unspecified if it will unset or
not touch attachments it could not map from the AVFrame.

The documentation of the return  value was wrong as well.

1fa7554bd6 avutil/hwcontext_videotoolbox: Unset undefined values 
When mapping AVFrame properties to the CVBuffer attachments, it is
necessary to properly delete undefined attachments, else we can
leave incorrect values in there guessed from VideoToolbox for
example, leading to inconsistent results where the AVFrame and
CVBuffer differ in metadata.
