Use av_log() rather than fprintf(stderr, ...), and show information
related to the previous size/pixel format configuration.

Consistent with the corresponding message issued in case of audio
configuration change.

The string "FFmpeg" was replaced by "Libav" in metadata that
got encoded in file headers.

The number of dba segments is the coded value + 1.
The coupling dba offset starts at the first coupling band, not at zero.

The constant values were never set, thus the evaluation of expressions
referencing those constants were resulting in an error.

PROFILE_ADVANCED doesn't set res_fasttx, so make that a special case
in the condition that decides which IDCT to use (and whether to read
coefficients transposed or not).

Redesign the way -aspect option is handled. This is done by making
ffmpeg read the sample aspect ratio set in the corresponding input
stream by default, and overriding it using the value specified by
-aspect.

If the output display aspect ratio is specified with -aspect, it is
set at the end of the filterchain, thus overriding the value set by
filters in the filterchain.

This implementation is more robust, since does not modify the
filterchain description (which was creating potential syntax errors).

There is no need to have 2 encoders, the input sample format can,does and should choose which is used

-pass, -top, -vc, and -qscale.

Check that the value passed for an OPT_INT option is an int, fail
otherwise.

IDCT coefficients are read transposed, but simple_idct does not expect
this. Therefore, only do tranposed coefficient reading if we're not
using simple_idct.
