ac80b812cd tta: prevents overflows for 32bit integers in header.
This prevents sample_rate/data_length from going negative, which
caused various crashes and undefined behaviour further down.

77cfb2563c configure: remove malloc_aligned.
It was to signal that allocations are 16-byte aligned, but AVX requires
32-byte alignment, thus the check is no longer useful (and causes
crashes).

82a0497cf3 vp8: update frame size changes on thread context switches.
This properly synchronizes frame size changes between threads if
subsequent threads abort decoding before frame size is initialized, i.e.
it prevents the thread after that from ping-ponging back to the original
value.

ababec7b95 arm: intreadwrite: disable inline asm for gcc 4.7 and later
Starting with version 4.7, gcc properly supports unaligned
memory accesses on ARM.  Not using the inline asm with these
compilers results in better code.

adebad07e0 arm: intreadwrite: fix inline asm constraints for gcc 4.6 and later
With a dereferenced type-cast pointer as memory operand, gcc 4.6
and later will sometimes copy the data to a temporary location,
the address of which is used as the operand value, if it thinks
the target address might be misaligned.  Using a pointer to a
packed struct type instead does the right thing.

The 16-bit case is special since the ldrh instruction addressing
modes are limited compared to ldr.  The "Uq" constraint produces a
memory reference suitable for an ldrsb instruction, which supports
the same addressing modes as ldrh.  However, the restrictions appear
to apply only when the operand addresses a single byte.  The memory
reference must thus be split into two operands each targeting one
byte.  Finally, the "Uq" constraint is only available in ARM mode.
The Thumb-2 ldrh instruction supports most addressing modes so the
normal "m" constraint can be used there.

4c387c7070 ppc: dsputil: do unaligned block accesses correctly
To load unaligned vector data in the usual way, explicit vec_ld()
should be used rather than dereferencing a pointer to a vector type.
When the VSX extension is enabled, gcc may compile vector pointer
dereferences using the VSX lxvw4x instruction instead of the lvx
instruction typically used with Altivec/VMX.  As the behaviour of
these instructions with unaligned addresses differs, it is important
that only lvx is used here.
