* commit '50a1c66cf6ab7eb683daaa9e2da3869fa3a54609':
ac3_parser: add a public function for parsing the data required by the demuxer
avpriv_ac3_parse_header() is left in place but without the
GetBitContext parameter, as the mov muxer requires a lot more fields
than just bitstream_id and frame_size from the AC3HeaderInfo struct.

this is somewhat a magic number, which can be understood from reading section
"7.1.2 Exponent Strategy" of the ac3 specification, in short:
Three exponents each represented as number 0-4 are grouped together and
base-5 encoded, so the maximal correct value is 25*4 + 5*4 + 4 = 124.

Currently when using target_level with EAC3 it produces silence. This small patch fixes target_level for decoding EAC3.
Example:
ffmpeg -y -i /tmp/test.wav -acodec eac3 -dialnorm -14 -ac 6 -b:a 384000 /tmp/test.m2ts
ffmpeg -y -target_level -24 -i /tmp/test.m2ts -acodec pcm_s16le -f matroska /tmp/out.mkv
ffplay /tmp/out.mkv

Change log level from warning to debug: the E-AC-3 "core"
substream can be successfully decoded without the additional
and dependent substreams, and their presence is already
indicated via avpriv_request_sample in ff_eac3_parse_header.

The table in question is a 253 byte one. In fact, it turns out that
dynamic generation of the table results in an increased binary size.
Code compiled with GCC 5.2.0, x86-64 (size in bytes), before and after
patch:
old: 62321064 libavcodec/libavcodec.so.57
new: 62320536 libavcodec/libavcodec.so.57
Thus, it always make sense to statically allocate this.
Tested with FATE with/without --enable-hardcoded-tables.
