There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

It is an implementation detail of other input formats whether
they use raw_codec_id or not. The HLS demuxer should not rely
on this.

The code currently presumes that a return value of AVERROR(ENOMEM)
implies that ac3hdr could not be allocated, so it need not be freed.
Yet any avpriv_ac3_parse_header() might allocate more than the
AC3HeaderInfo internally (it doesn't currently), so simply free
it unconditionally.
Fixes Coverity issues #1492870 and #1492868.

Move AC3HeaderInfo into ac3_parser_internal.h and the rest
into a new header ac3defs.h.
This also breaks an include cycle of ac3.h and ac3tab.h
(the latter now only needs ac3defs.h).

It is small (16 B) and therefore the overhead of exporting it more
than outweighs the size savings from not having duplicated symbols:
When the symbol is no longer avpriv, one saves twice the size of
the string containing the symbols name (2x30 byte), two entries
in .dynsym (24 bytes each on x64), one entry in the importing libraries
.got and .rela.dyn (8 + 24 bytes on x64) and two entries for the
symbol version (2 bytes each) and one hash value in the exporting
library (4 bytes).
(The exact numbers are of course different for other platforms
(e.g. when using dlls), but given that the strings saved alone
more than outweigh the array size it can be presumed that this
is beneficial for all platforms.)
