The codec uses all previous frames as reference frames, so they
certainly must be preserved and readable.

Changing the lowres value is risky because the user application may have a
local copy and not read back into it, or not undo some lowres dependant things.
A patch implementing this in ffplay is already on ffmpeg-dev, so this feature
should be back soon.
This reverts commit 125ea3ee06.
* qatar/master:
avformat: Avoid a warning about mixed declarations and code
BMV demuxer and decoder
matroskaenc: Make sure the seekhead struct is freed even on seek failure
mpeg12enc: Remove write-only variables.
mpeg12enc: Don't set up run-level info for level 0.
msmpeg4: Don't set up run-level info for level 0.
avformat: Warn about using network functions without calling avformat_network_init
avformat: Revise wording
rdt: Set AVFMT_NOFILE on ff_rdt_demuxer
rdt: Check the return value of avformat_open
rtsp: Discard the dynamic handler, if it has an alloc function which failed
dsputil: use cpuflags in x86 versions of vector_clip_int32()

Actually check the return value of DecodeBegin, to make
sure that it has encountered no errors.

Remove the CODEC_CAP_LOSSLESS flag, as it doesn't make
any sense for a decoder to use it.

Since buf_size is only used in this one function, there
is no reason for it to be part of UtVideoContext.

The caller expects the seekhead struct to be freed when calling
matroska_write_seekhead. Currently, the structure is leaked if the
seek fails.

run: The number of zero coefficients preceding a non-zero coefficient,
in the scan order. The absolute value of the non-zero coefficient is
called "level".
The run-level code makes illegal reads when trying to set up tables for
nonsense level 0.

Width and height, as used in utvideo_decode_frame, do not
need to be unsigned, and it could cause sign-compare
warnings later on.

It might make sense not to make the function completely mandatory
immediately at the next bump, which might be quite soon after
the function was introduced.

The original format field in Ut Video's extradata
should not be used to determine the output format.
Cases can occur where the original format differs
from the actual current format, and thus should
not be used as the output format. Instead, rely
solely on the FOURCC.

The new design allows to specialize the format for continuos time values
and discrete values. In particular, allows to print integer values like
"12" rather than "12.000".
Prettify, simplify parsing for integer values.
This makes rdt work again, which has been broken since
603b8bc2a1. This commit made
opening a demuxer without a file (or in this case, with a filename
which can't be opened) fail, unless the demuxer actually declared
AVFMT_NOFILE.
