1afddbe59e avpacket: use AVBuffer to allow refcounting the packets.
This will allow us to avoid copying the packets in many cases.

This breaks ABI.

9ae80e6a9c id3v2: fix reading unsynchronized frames.
Current code would incorrectly process e.g. 'ff 00 ff 00 ff' to
'ff ff ff', while it should be 'ff ff 00 ff'.

Fixes Bug 395.

049ce4facb id3v2: strdup the genre name explicitly.
It would have been done anyway in the av_dict_set() call.

This simplifies the code and avoid a warning because of assigning a
const string from ff_id3v1_genre_str to a non-const variable.

6e9bbc6525 id3v2: Match PIC mimetype/format case-insensitively
Some files' embedded art seems to have the mimetype 'image/JPG' instead
of 'image/jpg'. Libav fails to parse those because it matches
case-sensitively.

Use av_strncasecmp() to fix this behaviour.

385ec296f1 id3v2: Support v2.2 PIC
id3 v2.2 uses image format ("JPG","PNG") instead of mimetypes.

Currently, the attached picture is skipped because the format string
does not match a known picture mimetype.

This patch fixes this behaviour.

7a019dffe5 id3v2: add support for non-text and GEOB type tag frames
This extends the ID3v2 parser to allow for reading of non-text (i.e.
other than T***) meta tag frames providing a ff_id3v2_read_all()
function. An additional data structure 'ID3v2ExtraMeta' is introduced
for these tags since AVDictionary is string oriented and unsuitable
for binary data.

A parser for tag frames of type GEOB is implemented, which is needed
to extract keyring information from encrypted OMA files. GEOB data
is parsed into 'ID3v2ExtraMetaGEOB' data structures.

The routine to decode characters from different encodings to UTF-8,
formerly part of the read_ttag() function, is moved to its own
function. Because some tag frames contain subparts of unknown length,
the function is now also able to read until a null character is found.
In addition, the function now takes care of allocating a buffer long
enough to hold the decoded characters.

b7effd4e83 avio: avio_ prefixes for get_* functions
In the name of consistency:
get_byte           -> avio_r8
get_<type>         -> avio_r<type>
get_buffer         -> avio_read

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return
something useful.
