MFC r242256:

 Improve m_cat() by being able to also merge contents from M_EXT
 mbuf's by doing proper testing with M_WRITABLE().

 In m_collapse() replace an incomplete manual check for M_RDONLY
 with the M_WRITABLE() macro that also tests for shared buffers
 and other cases that make a particular mbuf immutable.
