Prepare for optimised forward MDCT implementations
...
This adds a function pointer for forward MDCT to FFTContext and
initialises it with the existing C function. ff_calc_mdct() is
changed to an inline function calling the selected version as
done for other fft/mdct functions.

Make DECLARE_ALIGNED_8 align to 8 bytes, never to 16
...
The DECLARE_ALIGNED_8 macro is defined to align to 16 bytes instead
the 8 suggested by the name on some CPUs. None of the uses of this
macro ever need 16-byte alignment, cases which once did having been
changed to always specify 16 bytes explicitly.

idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.
...
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

Support for getting (i)MDCT output multiplied by a constant scaling factor.
...
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

Convert asm keyword into __asm__.
...
Neither the asm() nor the __asm__() keyword is part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).
Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 syntax.
