dc2d0e06af mlpdec: support TrueHD streams with an Atmos substream
The fourth substream is being discarded, since its not raw audio data,
but an encoded Atmos stream which needs a specialized decoder.

Fixes decoding of the true hd stream from Transformers\ -\ Age\ of\ Extinction\ 2014\ 1080P-003.mkv

e4cbf7529b Give all anonymously typedeffed structs in headers a name
Anonymous structs cannot be forward declared and have no benefit.

a55247e761 Specify maximum sample rate of MLP by defining the factor relative to 48000
instead of directly.
This makes clear that the code assumes the maximum sample rate to be
a multiple of 48000 and also removes the division from the MAX_BLOCKSIZE
macros, which causes an issue with the Solaris assembler where "/" is
a comment marker unless the --divide option is used.

420df93037 mlpdec: Don't overallocate buffers.
Now that max channels and primitive matrices are properly validated, there is
no need to be paranoid that random data will be overwritten.
As a bonus this makes matrix_coeff 16-byte aligned between matrices.

7a2efd2e44 mlp: initialize all CRC tables in a common function.
This way the decoder does not have to depend on the parser being initialized
before.

987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
