avformat/hlsenc: temp_file usage for master playlist and vtt playlist
currently master playlist and subtitle playlist creation does not use
temporary files even when temp_file flag is set. Most of the use cases
it is not a problem because master playlist creation happens once on the
beginning of the whole process. But if master playlist is periodically
re-created because of master_pl_refresh_rate is set, non-atomic playlist
creation may cause problems in case of live streaming. This patch
correct this behavior by adding this functionality.

Commit 31f9032b added the audio_preload feature; its goal is to
interleave audio earlier than the rest. Unfortunately, it has never ever
worked, because the check for whether a packet should be interleaved
before or after another packet was completely wrong: When audio_preload
vanishes, interleave_compare_dts returns 1 if the new packet should be
interleaved earlier than the packet it is compared with and that is what
the rest of the code expects. But the codepath used when audio_preload is
set does the opposite.
Also fixes potential undefined behaviour (namely signed integer
overflow).

avformat/matroskadec: Improve read error/EOF checks I
ebml_read_num had a number of flaws:
1. The check for read errors/EOF was totally wrong. E.g. an EBML number
beginning with the invalid 0x00 would be considered a read error,
although it is just invalid data.
2. The check for read errors/EOF was done just once, after reading the
first byte of the EBML number. But errors/EOF can happen inbetween, of
course, and this wasn't checked.
3. There was no way to distinguish when EOF should be an error (because
the data has to be there) for which an error message should be emitted
and when it is not necessarily an error (namely during parsing of EBML
IDs). Such a possibility has been added and used.
All this was fixed; furthermore, the error messages for invalid EBML
numbers were improved and useless initializations were removed.

Get rid of pr dependency and write the columns strictly
alphabetical without page size considerations (POSIX
specifies 66 lines as default).
Setting the page size via pr's -l option was considered,
but as there is issue #5680 which wants to avoid pr
mainly because it's not in busybox, we chose to replace
pr instead.
Before pr would attempt to write pages, thus if a page
boundary was reached, the output looked confusing as one
couldn't see there was a new page and the alphabetical
order was disrupted when scanning down one of the columns.
This change is based on a shell implementation submitted
before by Yejun.
Possible differences to the current version using pr:
1. pr implementations should truncate items to not overflow columns;
depending on how it's done not truncating shall be better IMHO.
2. pr implementations might balance columns differently;
we use minimum number of lines and might end up not
using all columns or might have lesser entries in the
last column(s)
3. we use spaces only for padding the columns; at least the GNU pr
version on my system also by default stuffs in tabs in addition
to a single space in between columns. I don't see that this
behaviour is demanded by POSIX, though I might be very well
overlooking things. Anyway for our use case I can't see a need
for having the additional tabs, or why it would be better compared
to padding with spaces only.
Fixes output for sizes with width < column width, too.

avformat/matroskadec: Treat SimpleBlock as EBML_BIN
Up until now, the SimpleBlock was treated specially: It basically had
its own EBML category and it was also included in the BlockGroup EBML
syntax (although a SimpleBlock must not exist in a BlockGroup according
to the Matroska specifications). The latter fact also meant that
a MatroskaBlock's buffer was always unreferenced twice.
This has been changed: The type of a SimpleBlock is now an EBML_BIN.
The only way in which SimpleBlocks are still different is that they
share their associated structure with another unit (namely BlockGroup).
This is also used to unref the block: It is always unreferenced via the
BlockGroup syntax.

Every new element of an EbmlList is zeroed initially in

By default, the data_offset member of the AVFormatInternal of the
AVFormatContext associated with the MatroskaDemuxContext has not been
initialized explicitly by any Matroska-specific function, so that it was
initialized by default to the offset at the end of matroska_read_header,
i.e. usually to the offset of the length field of the first encountered
cluster. This meant that in case that the Matroska-specific seek-code
fails because there are no index entries for the target track a seek to
data_offset would be performed and ordinary parsing would start from
there which is nonsense: The length field would be treated as EBML ID and
(if the length field is not longer than four bytes (EBML numbers that
long are rejected as invalid EBML IDs)) whatever comes next would be
treated as its EBML size although it simply isn't.

in this function the result buffer is the same as the
