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).

The mov flavour of timed text uses the first two bytes of the packet as
a length field. And up until 11bef2fe said length field has been read
correctly in the mov2textsub bsf. But since then the next two bytes are
read as if they were the length field. This is fixed in this commit.

Up until now, when an element was skipped, it was relied upon
ffio_limit to make sure that there is enough data available to skip.
ffio_limit itself relies upon the availability of the file's size. As
this needn't be available, the check has been refined: First one byte
less than intended is skipped, then another byte is read, followed by a
check of the error flags.

This commit fixes a number of bugs:
1. There was no check that no read error/EOF occured during
ebml_read_uint, ebml_read_sint and ebml_read_float.
2. ebml_read_ascii and ebml_read_binary did sometimes not forward
error codes; instead they simply returned AVERROR(EIO).
3. In particular, AVERROR_EOF hasn't been used and no dedicated error
message for it existed. This has been changed.
In order to reduce code duplication, the new error code NEEDS_CHECKING
has been introduced which makes ebml_parse check the AVIOContext's
status for errors.

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.
