16bb8247b4 avcodec/mpegaudiodsp: Make initializing synth windows thread-safe
These arrays are used by the Musepack decoders, the MPEG audio decoders
as well as qdm2 and up until now, these arrays might be initialized more
than once, leading to potential data races as well as unnecessary
initializations. Therefore this commit ensures that each array will only
be initialized once.

ead3134150 avcodec/mpegaudiodsp: Make ff_mpadsp_init() thread-safe
The only thing missing for this is to make ff_mpadsp_init_x86()
thread-safe; it currently isn't because a static table is initialized
every time ff_mpadsp_init() is called (when ARCH_X86 is true). Solve
this by initializing this table only once, namely together with the
ordinary not-arch specific tables. This also allows to reuse their AVOnce.

5c45f7e156 avcodec/mpegaudiodsp: Combine initializing float and int tables
This avoids code duplication in the functions used to initialize them
and allows to remove an AVOnce.

2caa93b813 mpegaudiodsp: Change type of array stride parameters to ptrdiff_t
This avoids SIMD-optimized functions having to sign-extend their
stride argument manually to be able to do pointer arithmetic.

30%/25% (fixed/float) faster mp3 decoding on Apple's A7. The floating
point decoder is approximately 7% faster.
