De-inline the mbuf and cluster allocation functions and mechanically
move them to kern/kern_mbuf.c with exception of m_extaddref() which
going to kern/uipc_mbuf.c.

Having all mbuf and cluster allocation functions as real functions
again gives us significant future freedom in optimizing the backend
allocator without breaking the ABI for drivers.

As a side-note the function call overhead on modern CPUs is very low
and in other cases micro-benchmarks have shown that de-inlining actually
slightly improved performance by reducing the number of instructions and
improving I-cache efficiency.  This change hasn't been measured yet
though.
