When the deprecated option "user-agent" was set to something different
than its default value, said option would always precede and overwrite
the ordinary user_agent option (regardless of whether it was explicitly
set) which leads to a leak of the user_agent option (which has a default
value, so the leak happens always).
Fix this by setting the same destination for both options; the last
option applied wins then.

Some FATE tests use files created by other FATE tests as input files;
this mostly affects the seek tests which use files from vsynth_lena as
well as acodec-pcm as input files. In order to make this possible the
temporary files of all the vsynth* and all acodec-pcm tests are kept.
Yet only a fraction of these files are actually used. This commit
changes this to only keep the files that are actually needed for other
tests. This reduces the size of the tests/data/fate folder after a full
FATE run from 2024727441B to 138739312B.

While this usage of strncpy is correct, said function nevertheless has
the disadvantage of not automatically ensuring that the destination
string is zero-terminated. So av_strlcpy should be preferred.
This also removes a -Wstringop-truncation warning from GCC (it doesn't
matter whether the buffer is truncated, as long as it can fit all
the names of the supported codecs).

The fourccs used by the Megalux Frame format to determine the pixel
format are actually no fourccs at all as they are a single byte.
Furthermore, their range is continuous (1-5), so they are actually
ordinary indices. So treat them as such and don't use PixelFormatTags
for them.

This flag was added in 492026209b
in conjunction with av_demuxer_open() to allow to pass private
options to demuxers. It worked as follows: av_open_input_stream()
(the predecessor of avformat_open_input()) would not call the
read_header function if this flag is set. Instead the user could set
private options of the demuxer via the format's private class after
avformat_open_input() and then call av_demuxer_open() which called
the format's read_header function.
This approach was abandoned in e37f161e66
and av_demuxer_open() deprecated; instead the AVDictionary based way of
passing private options to the demuxer was choosen. Yet
AVFMT_FLAG_PRIV_OPT has never been deprecated and av_demuxer_open()
never removed. This commit implements the deprecation of the flag and
schedules av_demuxer_open for removal on the next major bump.
Given that av_demuxer_open() has been deprecated in 2012 and that this
flag is useless without it, the flag will be ignored after the next
major version bump.

strncpy only ensures that one does not write beyond the end of the
destination buffer; in case of truncation it does not zero-terminate
the destination buffer. This makes using it the way it is now in the
DASH demuxer dangerous. So use av_strlcpy instead.
Also don't write anything if there is no id: The buffer has already been
zeroed initially.
The DASH testset from the Universität Klagenfurt contains samples with
ids that are too long. E.g.

The obstacle to do so was in filter_codec_opts: It uses searches
the AVCodec for options via the AV_OPT_SEARCH_FAKE_OBJ method, which
requires using a void * that points to a pointer to a const AVClass.
When using const AVCodec *, one can not simply use a pointer that points
to the AVCodec's pointer to its AVClass, as said pointer is const, too.
This is fixed by using a temporary pointer to the AVClass.
