Simplify, increase robustness in case a new sample format is added.

Improve consistency.

This is better than silently ignoring the option, which results in
unexpected quality results.

The option belongs to libavcodec, so it results duplicated in the file.

In ISO/IEC 13818-2, bit rate is differently determined according to video type

1) MPEG1 Video
 Bit_rate and vbv_delay are set to 3FFFF and FFFF respectively
 to indicate variable bitrate. Other values are for constant bitrate.
 VBV is only defined for constant bit rate operation.
 Ths STD supersedes the VBV model for vbr.

2) MPEG2 Video
 Even if the bitrate is constant, the value of bit_rate may not be the actual bitrate
 since bit_rate need only be an upper bound to that actual bitrate.
 VBV is only defined for variable bit rate operation.
 Constant bit rate is viewed as a special case of vbr.

"mmxext" is a more sensible name and more common in outside projects.

Requested in trac ticket #1857.

It is useful to use bprint to handle a growing buffer
used with another API.

right above there is if (pkt) {<do stuff>; pkt = NULL}, so pkt is just a
fancy name for NULL at this point.
