This reverts commit d15c21e5.

After the major bump this is no longer necessary.

In addition to the recent tables mess, the AVOption defaults behavior
changed, so an old lavc used with a new lavu will get completely messed
up defaults.

Fixes a crash when using a preset with stream copy.

This allocates 4 bytes less than the previous code if avctx->block_align is
a multiple of 4, but the extra 4 bytes is not really needed.

also does some minor refactoring.

This defines an AVCodec only if the corresponding CONFIG option is
enabled instead of using the broad CONFIG_ENCODERS/DECODERS.

Since it is declared as a string AVOption, the generic freeing code
attempts to free it on codec close. Some codecs might have already freed
it elsewhere (or didn't even allocate it with av_malloc() in the first
place), so this might lead to an invalid free.

There is no point in having this field accessible as an AVOption, so
remove it from the options table.

Fixes Bug 380.

Error out on init if a codec with CODEC_CAP_EXPERIMENTAL is requested
and strict_std_compliance is not FF_COMPLIANCE_EXPERIMENTAL.

Move the check from avconv to avcodec_open2() and return
AVERROR_EXPERIMENTAL accordingly.
