f37bfd3f62 avformat/dashdec: propagate icy to child AVIOContexts
When the user decides they do not want to to send the Icy-MetaData
header, this should be respected for all requests, not just the first
one.

Fix #5578

9bde6c6be0 avformat/microdvd: Use \n instead of \0 to end file header
Up until now, the microdvd demuxer uses av_strdup() to allocate the
extradata from a string; its length is set to strlen() + 1, i.e.
including the \0 at the end. Upon remuxing, the muxer would simply copy
the extradata at the beginning, including the \0.

This commit changes this by not adding the \0 to the size of the
extradata; the muxer now delimits extradata by inserting a \n. This
required to change the subtitles-microdvd-remux FATE-test.

Furthermore, the extradata is now allocated with zeroed padding.

The microdvd decoder is not affected by this, as it didn't use the size
of the extradata at all, but treated it as a C-string.

28d02524a0 avformat/flvenc: Forward errors from allocating keyframe index
While the function adding a new element to the keyframe index checked
the allocation, the caller didn't check the return value. This has been
changed. To do so, the return value has been changed to an ordinary ret
instead of pb->error. This doesn't pose a problem, as write_packet() in
mux.c already checks for write errors (since 9ad1e0c1).

!(c->pix_fmt != AV_PIX_FMT_NONE || c->got_format_from_params)

equals

(c->pix_fmt == AV_PIX_FMT_NONE) && !c->got_format_from_params

1. When (c->pix_fmt == AV_PIX_FMT_NONE) is true, got_format_from_params is
always false, the flag doesn't contribute to the result.

2. When the first part is false, the second part doesn't matter, the flag
doesn't contribute to the result.

The result only depends on c->pix_fmt.

5ba3a8958c avformat/hlsenc: Fix memleaks with repeating parameters
When a parameter like e.g. language is contained more than once in the
part of var_stream_map pertaining to a single VariantStream, the later
one just overwrites the pointer to the earlier one, leading to a
memleak. This commit changes this by handling the situation gracefully:
The earlier string is silently freed first, so that the last one wins.
