e9eb8d0bce avio: avio: avio_ prefixes for put_* functions 
In the name of consistency:
put_byte           -> avio_w8
put_<type>         -> avio_w<type>
put_buffer         -> avio_write

put_nbyte will be made private
put_tag will be merged with avio_put_str

e63a362857 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.

ae99313aa5 avio: move init_put_byte() to a new private header and rename it

496c645d3b Never shrink the ByteIOContext buffer in ff_rewind_with_probe_data 
If there is little unread data in the ByteIOContext buffer, this may lead
to reducing the size of the ByteIOContext buffer to little more the probe
data size. This can lead to suboptimal aviobuf behaviour, e.g. making some
demuxers fail to do short seeks backwards (if the input isn't seekable).

7f7686dfb1 Make get_buffer and get_partial_buffer return url_ferror or AVERROR_EOF as 
appropriate if it couldn't read any data at all.
This should make handling of EOF and error simpler or make it work right without
extra code in a few place (e.g. raw demuxer).
