f75f4194d1 Restructure av_log_missing_feature message
Some invocations include a verb in the log message, others do not.  Yet
av_log_missing_feature expects callers to provide a verb.  Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.

5e50a5724b Revert "removing lowres support"
There have been multiple user complaints about loosing this feature
while its not clear the 3% speedloss claims where real or fabricated.
My own testing indicates no statistically significant speed difference
both with mpeg2 and mpeg4, and if at all the code with lowres support
is a tiny bit faster than without.

This reverts commit 92ef4be4ab, reversing
changes made to 2e07f42957.

5eec5a79da jpeg: handle progressive in second field of interlaced.
Progressive data is allocated later in decode_sof(), not allocating
that data leads to NULL dereferences.

70d54392f5 lowres2 support.
The new lowres support is limited to decoders where lowres decoding
is possible in high quality.
I was not able to measure any speed difference, but if one is found
the 2-3 lines that might affect speed can be made compile time conditional
