d2961e4ebf id3v2: read TXXX frames with two calls to decode_str() instead of one. 
Read the key in the first, value in the second.

This allows to avoid pointless strdups and simplify decode_str() by
dropping two of its parameters.

1e18d32d01 id3v2: don't discard the whole tag when encountering empty frames. 
While they're technically invalid, it's better to skip them and try to
read the rest of the tag.

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.

existing values with supposedly outdated ones.
