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...

Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

Split parts of dvdata.h into dvdata.c, this ensures that things like
work_chunks_* and dv_idct_factor_* variables appear only once in the binary
instead of 3 times.
Saves 3264 bytes in .rodata and 312416 bytes in .bss on x86_64.

Extend DV autodetection to also reliably detect single-frame DVs with
a higher score that MAX/4.
It checks that there are at least 10 DIF headers and at least one per
24000 bytes, and if so considers the file reliably detected as DV.
Passes probetest, too....

6377de61 09/14/2009 10:03 PM Reimar Döffinger

Try harder to avoid false positives for DV probe.
Require at least one signature match per provided 1MB of probe data,
and if there is only a single match, return at most MAX/4.
Fixes issue1382 but could/should probably still be improved.
