sys/altq: Memset zero before copyout.

Just in case of uninitialized padding which would lead to kernel
stack disclosure. If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.

Remove the 't' argument from m_tag_find().

kauth fallout

integrate kauth.

Complete the FREE -> free transition and add more NULL checks for malloc
returns. Although these cannot happen because M_WAITOK, the rest of the
