Include i420 buffers in Obj-C framework again.
These headers was lost in the cleanup CL for the Obj-C directories. This
puts them back in the framework headers.
Note that since the protocol and interface was split into two different
headers, and all public framework headers are put into a flat directory
structure, I had to rename the implementation files so they would not collide
in the framework header directory.
