b2c75b6e63 avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio()
This allows audio encoders to optionally take an AVFrame as input and write
encoded output to an AVPacket.

This also adds AVCodec.encode2() which will also be usable by video and
subtitle encoders once support is implemented in the public functions.

56f22b7e16 pcmenc: set frame_size to 0.
This indicates that the actual frame size is based on the buf_size passed to
avcodec_encode_audio().

0093f96d34 pcmdec: return buf_size instead of src-buf.
The values will always be the same, so this change eliminates an unneeded
variable. It also gets rid of the need to reset src when memcpy() is used.

85579b6381 avcodec: remove the Zork PCM encoder.
The Zork PCM decoder does not decode the 1 sample we have correctly, therefore
the encoder based on the decoder is also incorrect. There is no good reason to
keep the encoder.

b45eb9d619 pcm: reduce pointer type casting
Making 'samples' a pointer to uint8_t simplifies the DECODE
macro and reduces the amount of type casting overall.

This also fixes some signed overflows on left shift.

5b5083b5fe Don't declare a pcm_dvd encoder.
The PCM_DVD encoder would be left unused, as allcodecs.c properly declared
it as being decoder-only, but it would still be built into the object file.

Since there is no block of code to properly encode this PCM format, it's
not a full codec.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

"Google Summer of Code participation" on the mailinglist.

Also reset the minor version and fix the forgotton change to libfaad.
Note: The API/ABI should not be considered stable yet, there still may
be a change done here or there if some developer has some cleanup ideas and
