MAJOR: buffers: replace buf->r with buf->p + buf->i

This change gets rid of buf->r which is always equal to buf->p + buf->i.
It removed some wrapping detection at a number of places, but required addition
of new relative offset computations at other locations. A large number of places
can be simplified now with extreme care, since most of the time, either the
pointer has to be computed once or we need a difference between the old ->w and
old ->r to compute free space. The cleanup will probably happen with the rewrite
of the buffer_input_* and buffer_output_* functions anyway.

buf->lr still has to move to the struct http_msg and be relative to buf->p
for the rework to be complete.
