This duplicates the function fillPlane().

Remove duplicate "inC" and "_c" functions that do the same thing;
give each function that handles data and acts as a function pointer
a "_c" suffix; remove "_c" suffix from functions that are inherently
not optimizable. Remove inline keyword from functions that are only
used through function pointers.

The MPEG encoding code assumes that n_threads == n_slices, and thus it
should use n_slices even if threading itself is disabled.

The --output option is available in texi2html since at least version 1.78.

Most of these variables are only used in av_dlog statements, some

random_state was changed from an int to a struct and can no longer be printed
as easily as before.

Altivec sws code intentionally overreads buffers for better performance,
so we need to allocate larger buffers to handle that.
