94235f2ba2 indeo3: avoid writes without necessary alignment in copy_cell() 
Cells starting at a position aligned to 8 pixels but wider than
4 blocks are copied with 3 blocks per loop. This creates problems on the
next loop iterations since the routine copying 2 blocks requires the
same alignment on some architectures like ARM NEON.

7c00e9d8ae x86: ac3dsp: Remove 3dnow version of ff_ac3_extract_exponents 
The function requires increasing the fuzz factor for the ac3/eac3 encode

speedup for legacy CPUs that do not support SS2. Thus its benefit is not
worth the trouble it creates and fixing it would be a waste of time.

Intra codecs do not need an update_thread_context() function and never
call ff_thread_finish_setup(). They rely on ff_thread_get_buffer()
calling it. So call it even if the get_buffer2 function pointer is
avcodec_default_get_buffer2 and it has not been called before.
