RepeatPPS is enabled by default in mfx. It is not necessary mostly and
wasting encoding bits.
Add an option to control it and disable it by default.

The affected functions could also be changed into macros, this is the
smaller change to fix it though. And avoids (probably) less readable macros
The extra code should be optimized out when optimizations are done as all values
are known at build after inlining.

Such low resolution would result in empty output as a minimum of 4x4 is needed
We could also check for multiple of 4 dimensions but that is not needed

Frames that small are not valid and of limited use for error concealment, while
being very computationally intensive to process.

This commit ensures that all (potentially, long) filesystem activity is
performed when the user calls av_write_trailer on the DASH libavformat
context, not when freeing the context. Also, this defers media segment
deletion until after the media trailers are written.
Passes fate on LE (with "lavc/jrevdct: Avoid an aliasing violation" applied).

When dashenc has to run for long duration(say 24x7 live stream), one can enable this option to ignore the io failure of few segment's upload due to an intermittent network issues.
When the network connection recovers dashenc will continue with the upload of the current segments, leading to the recovery of the stream.
The only native HLS implementation in the wild (Safari browser) doesn't
support WebM. And at least some MSE-based players (e.g. shaka-player)
cannot handle WebM media segments when playing HLS. So just skip non-mp4
streams from HLS manifests. Note that such streams will still be described
by the DASH manifest and therefore consumed by players supporting DASH.
