4cdd6cac1f avformat/mpegts: Don't leave context in inconsistent state upon error 
Up until now, opening a section filter works as follows: A filter is
opened and (on success) attached to the MpegTSContext. Then a buffer for
said filter is allocated and upon success attached to the section
filter; on error, the filter is simply freed without removing it from
the MpegTSContext, leaving the latter in an inconsistent state. This
leads to use-after-frees lateron.

This commit fixes this by allocating the buffer first; the filter is
only opened if the buffer could be successfully allocated.

22cb13d4c5 avformat/webmdashenc: Avoid allocations, fix memleak 
When using the WebM DASH Manifest muxer, every stream of each adaptation
set has to contain a metadata entry containing the filename of the
source file. In case of live stream manifests, said filename has to
conform to a pattern of
<file_description>_<representation_id>.<extension>. These pieces are
used to create the other strings that are actually output. Up until now,
these other strings would be allocated, used once and then freed
directly after usage. This commit changes this: The function that
allocated and assembled these strings now returns pointers to the '_'
and '.' delimiters and so that the caller can easily pick substrings
from it without needing to copy the string.

Avoiding allocations also fixes a memleak: One of the allocated strings
would leak upon a subsequent allocation failure.

e114a337be avformat/matroskadec: Avoid undefined pointer arithmetic 
The Matroska demuxer currently always opens a GetByteContext to read the
content of the projection's private data buffer; it does this even if
there is no private data buffer in which case opening the GetByteContext
will lead to a NULL + 0 which is undefined behaviour.
Furthermore, in this case the code relied both on the implicit checks
of the bytestream2 API as well as on the fact that it returns zero
if there is not enough data available.

Both of these issues have been addressed by not using the bytestream API
any more; instead the data is simply read directly by using AV_RB. This
is possible because the offsets are constants.

f25caec87f avformat/mxfdec: Fix memleak upon repeating tags 
When parsing MXF encountering some tags leads to allocations. And when
these tags were encountered repeatedly, this could lead to memleaks,
because the pointer to the old data got simply overwritten with a
pointer to the new data (or to NULL on allocation failure). This has
been fixed.

6918d1281c avformat/mxfdec: Fix memleak when parsing tag fails 
The MXF demuxer uses an array of pointers to different structures of
metadata (all containing a common initial sequence containing a type
field to distinguish them) and some of these structures contain pointers
to separately allocated subelements. If an error happens while reading
and creating the tags, the semi-finished new tag is freed using the
function to free these tags. But this function doesn't free the already
allocated subelements, because the type has not been set yet. This commit
changes this.
