The underlying driver need not support B frames - since they are enabled
by default for some codecs, it is better to disable them rather than
returning an error in this case.  This makes the default settings usable
for low-power encoding on Intel platforms.

The default behavior of the mediacodec decoder before this commit
was to delay flushes until all pending hardware frames were
returned to the decoder. This was useful for certain types of
applications, but was unexpected behavior for others.

The new default behavior with this commit is now to execute
flushes immediately to invalidate all pending frames. The old
behavior can be enabled by setting delay_flush=1.

With the new behavior, video players implementing seek can simply
call flush on the decoder without having to worry about whether
they have one or more mediacodec frames still buffered in their
rendering pipeline. Previously, all these frames had to be
explictly freed (or rendered) before the seek/flush would execute.

The new behavior matches the behavior of all other lavc decoders,
reducing the amount of special casing required when using the
mediacodec decoder.

If there is a decoder initialization failure detected in avcodec_open2

'OMX.SEC.avc.dec' is a valid hardware decoder, while the decoders
we seek to blacklist all match 'OMX.SEC.*.sw.dec'.

ff_get_extradata() frees any existing extradata before allocating now,
and using av_free() here leaves a dangling pointer that will result in
a double free.

Fixes a regression since 0ca33b1d.

Look_ahead can provide quality improvements, but would better disable it by default due to some reasons:
1. It is only available for some codecs (e.g. HEVC is not supported) on Intel
   Haswell and plus platforms. Thus means it will be failed on some platforms.
2. It significantly increases encoding latency and memory consumption.
3. It may overwrite some other options such as CBR and CAVLC.

Right now, if someone configures ffmpeg with for example --enable-nvenc they will
get an error message complaining about missing cuda.
This is very confusing and already has lead people into installing the CUDA SDK,
even though it's not what they need.

This will make it complain about ffnvcodec instead.
