ff_get_extradata() frees any existing extradata before allocating now,
and using av_free() here leaves a dangling pointer that will result in
a double free.

Numeric hosts in certificates are not very common, but supported by LibreSSL.
Forward the IP address to make verification work in this case.
Fixes ticket #7029
This prevents leaks in the rare cases the function is called when extradata
already exists.

Look_ahead can provide quality improvements, but would better disable it by default due to some reasons:
1. It is only available for some codecs (e.g. HEVC is not supported) on Intel
Haswell and plus platforms. Thus means it will be failed on some platforms.
2. It significantly increases encoding latency and memory consumption.
3. It may overwrite some other options such as CBR and CAVLC.

The commit which added those was pushed prematurely before anyone could object
to illogical suffixes like just m for milliseconds. Without this, we'd be locked
into never being able to implement the "m" suffix for minutes.

Right now, if someone configures ffmpeg with for example --enable-nvenc they will
get an error message complaining about missing cuda.
This is very confusing and already has lead people into installing the CUDA SDK,
even though it's not what they need.
This will make it complain about ffnvcodec instead.

mov_read_ctts ignores ctts entries having count <= 0. Generally, the
aggregate of all ctts entries' count fields resulting from mov_read_ctts
can be less than the corresponding sample_count.
mov_build_index attempts to normalize any existing ctts_data counts to
be 1, to make a 1-1 mapping of a ctts_data entry to a sample.
That 1-1 mapping left a tail of uninitialized ctts_data entries when the
aggregate, normalized ctts_count < sample_count.
Even more generally, later usage of ctts_data may depend on the entire
ctts_allocated_size having been initialized.
This change memsets the entire allocation of the normalized ctts_data in
mov_build_index, to prevent use of uninitialized data later.

Due to the union construct, unused bits in bitplane_present.value might
be uninitialized even when the used bits are all set to a value.
Masking the unused bits prevents spurious true values when all used
bits are unset, e.g. skipped pictures.

nvenc doesn't support P016, but we have two problems today:
1) We declare support for YUV444P16 which nvenc also doesn't support.
We do this because it's the only pix_fmt we have that can
approximate nvenc's internal format that is YUV444P10 with data in
MSBs instead of LSBs. Because the declared format is a 16bit one,
it will be preferrentially chosen when encoding >10bit content,
but that content will normally be YUV420P12 or P016 which should
get mapped to P010 and not YUV444P10.
2) Transcoding P016 content with nvenc should be possible in a pure
hardware pipeline, and that can't be done if nvenc doesn't say it
accepts P016. By mapping it to P010, we can use it, albeit with
truncation. I have established that swscale doesn't know how to
dither to 10bits so we'd get truncation anyway, even if we tried
to do this 'properly'.
To make the best use of existing code, I generalised the wrapper
that currently does yuv420p10 to p010 to support any mixture of
input and output sizes between 10 and 16 bits. This had the side
effect of yielding a working code path for all yuv420p1x formats
to p01x.
