lumscale/lumshift don't get reset back to their default values if
intensity compensation is not active, and a wrong signaling here can
cause playback issues.

1 is the only valid value for VC-1/WMV3, and setting it here makes sure
no invalid value is send to a hw accelerator, for example.

These are not supported by all compilers (gcc 2.95 but also older SPARC
compilers, see gcc bug #33304 for example), and there is no real need for them.
One use of this feature remains in libavdevice/v4l2.c which can't be
replaced quite as easily.

Add ff_id3v2_read_dict() for parsing without AVFormatContext, but
instead with AVIOContext and AVDictionary.
AVFormatContext is still used for logging, if available.
Chapter parsing is the only non-logging functionality that actually
needs AVFormatContext, and AFAICS it should be modified to write the
data to ID3v2ExtraMeta first, from where it can be implanted to
AVFormatContext by a separate function (like it is done with
read_apic() and ff_id3v2_parse_apic()). That is outside the scope of
this patch, though.

Add AVOptions for setting the initial offset and the ending offset, so
they can be used for setting an appropriate Range header.

Used in some HLS streams ("Timed Metadata for HTTP Live Streaming").
This is just ID3 tags at arbitrary stream positions, but I still added
"timed" to the codec name to avoid confusion with regular non-stream ID3
tags.

This is to prevent regressions in case the old code was able to partly
decode frames (no way to say without a testcase)
Add a memset to prevent use of uninitialized memory until we have a
testcase and can test/fix it

Some older compilers might have particular trouble with them,
and they do not really seem worth it to me.

In particular the mutex initialization for example won't actually
compile with e.g. gcc 2.95.

Since we have this compat/va_copy.h header already we might just as well make
use of it for more than one compiler.

The code seems to have never been tested
fixing it should be quite easy but needs a sample/testcase
