Subject: Clean up the declarations and comments of some of the variables in
X-Git-Tag: 2.0.28~2

Clean up the declarations and comments of some of the variables in
ap_get_client_block.
There were two len_read vars (each of different types), so the outer one
was shadowed - move it to the correct scope.
Move apr_bucket* old declaration inside of the loop so it is obvious
what its scope is.
