8e42ba4c80 simplify WEBP_EXTERN macro 
including the type in the macro doesn't bring much benefit to ordering,
current platforms work with a prefix, this would be insufficient if the
attribute needed to follow the function prototype. this form makes it
easier to override on the command line.

8acb4942f7 Remove the argb* files. 
Half of the functionality was duplicated.
The rest is about the alpha channel handling so we
might as well put it in the appropriate file.

from PackARGB.

Currently, none are available. If WEBP_HAVE_SSE2 eventually works,
we'll have to refine this conditionals.

9b3aca404d NEON: fix overflow in SSE NxN calculation 
vmlal_u8() is prone to overflow during the accumulation.
There was a mismatch happening at low q mostly. Because in this
case the distortion is important and the accumulated sum was
later than 16bit-unsigned.
