hlsdemux: Re-use streams if possible

When switching variants, try to re-use existing streams/pads instead of creating
new ones. When dealing with urisourcebin and decodebin3 this is not only the
expected way but also avoids a lot of buffering/hang issues.

waylandsink: release frame callback when destroyed

We would use a frame callback from the surface to indicate
that last buffer is rendered, but when we destroy the surface
and that callback is not back yet, it may cause the wayland event
queue crash.

rtmp2src: Set buffer timestamp on output buffer

This timestamp information would be useful for queue2 element
when calculating time level and also it makes buffering decision
more reliable.

Check whether conversion with given combination of input/output
format and dxgi colorspace is supported or not by driver.
If not, we should use shader.

va: pool: Set the video_alignment after we get image info.

The set_format() of the allocator may change the stride of the
alloc_info. We should update the video_align.stride_align based
on it. Or, we get a warning in gst_video_meta_validate_alignment().

va: h264dec: Set the padding to VideoAlignment's right.

In our va implemenation, we just use image's info to map the buffer.
The padding info just plays a role as a place holder to expand the
allocation size in caps when decoding size is bigger than display
size. So the padding_right or padding_left does not change the result.
But we find if using padding_left, it is hard to meet the requirement
of gst_video_meta_validate_alignment(), when the video meta's stride
is different from the allocation width.

va: basedec: No need to call base class' decide_allocation().

We have already done the jobs in gst_va_base_dec_decide_allocation()
and no need to call base class' decide_allocation() again. The base
class' decide_allocation() will set_format() again and let use do the
image/surface testing again, which is low performance and no needed.

va: allocator: use _update_image_info() to set allocator parameters.

Use this standalone function to update the allocator info and make
all ensure_image() and mem_alloc() API clean.
We also change the default way of using image. We now set the non
derive manner as the default manner, and if it fails, then fallback
to the derived image manner.
On a lot of platforms, the derived image does not have caches, so the
read and write operations have very low performance.

va: allocator: Decide the allocator's parameters when set_format().

Moving the parameters testing and setting from the allocator_alloc_full()
to the allocator_try(). The allocator_alloc_full() will be called every
time when we need to allocate a new memory. But all these parameters such
as the surface and the image format, rt_format, etc, are unchanged during
the whole allocator lifetime. Just setting them in set_format() is enough.
