ff_mp4_obj_type contains the wrong type of tags for
AVOutputFormat.codec_tag. AVOutputFormat.codec_tag is used to
validate AVCodecParameters.codec_tag so needs to be the same
type of tag.

Creates new tag lists for mp4 and ismv.  New tag lists support
same list of codecs found in ff_mp4_obj_type. psp uses the same
tag list as mp4 since these both use mp4_get_codec_tag to look up tags.

This implements the 0x10 frame format for Interplay MVE movies. The
format is a variation on the 0x06 format with some changes. In addition
to the decoding map there's also a skip map. This skip map is used to
determine what 8x8 blocks can change in a particular frame.

This format expects to be able to copy an 8x8 block from before the last
time it was changed. This can be an arbitrary time in the past. In order
to implement this this decoder allocates two additional AVFrames where
actual decoding happens. At the end of a frame decoding changed blocks
are copied to a finished frame based on the skip map.

The skip map's encoding is a little convulted, I'll refer to the code
for details.

Values in the decoding map are the same as in format 0x06.

This implements the 0x06 frame format for Interplay MVE movies. The
format is relatively simple. The video data consists of two parts:

16 bits per 8x8 block movement data
a number of 8x8 blocks of pixel data

For each 8x8 block of pixel data the movement data is consulted. There
are 3 possible meanings of the movement data:
* zero     : copy the 8x8 block from the pixel data
* negative : copy the 8x8 block from the previous frame from an offset
             determined by the actual value of the entry -0xC000.
* positive : copy the 8x8 block from the current frame from an offset
             determined by the actual value of the entry -0x4000

Decoding happens in two passes, in the fist pass only new pixeldata is
copied, during the second pass data is copied from the previous and
current frames.

The codec expects that the current frame being decoded to still has the
data from 2 frames ago on it when decoding starts.

Interplay MVE movies have a SEND_BUFFER operation. Only after this
command does the current decoding buffer get displayed. This is required
for the other frame formats. They are fixed-size and can't always encode
a full frame worth of pixeldata.

This code prevents half-finished frames from being emitted.

If flushing is not disabled, then mux.c will signal the end of the packets with
an AVIO_DATA_MARKER_FLUSH_POINT, and aviobuf will be able to decide to flush or
not based on the preferred minimum packet size set by the used protocol.

This patch makes aviobuf work more like traditinal file IO, which is how people
think about it.

For example, in the past, aviobuf only flushed buffers until the current buffer
position, even if more data was written to it previously, and a backward seek
was used to reposition the IO context.

From now, aviobuf will keep track of the written data, so no explicit seek will
be required till the end of the buffer, or till the end of file before flushing.

This fixes at least one regression, fate-vsynth3-flv was broken if
flush_packets option was set to false, an explicit seek was removed in
4e3cc4bd.

Also from now on, if a forward seek in the write buffer were to cause a gap
between the already written data and the new file position, a flush will
happen.

The must_flush varable is also removed, which might have caused needless
flushes with multiple seeks whithin the write buffer. Since we know the amount
of data written to it, we will know when to flush.
