A piece of code was added to install a host route when an IPv6 interface
address is configured with a /128 prefix. This is no longer necessary due
to r192011. In fact that code conflicts with r192011. This patch removes
the host route installation when detecting the /128 prefix, and instead
let the code added by r192011 to install the loopback route for that IPv6
interface address.

MFC r196149:
Add a check for a NULL mbuf ptr at the beginning of xdrmbuf_inline()
so that it returns failure instead of crashing when "m->m_len" is
executed and m == NULL. The mbuf ptr can be NULL when a call to
xdrmbuf_getbytes() gets the bytes it needs, but they are at the end
of a short RPC reply. When this happens, xdrmbuf_getbytes() returns
success, but advances the mbuf ptr (xdrs->x_private) to m_next, which
is NULL. If this is followed by a call to xdrmbuf_getlong(), it calls
xdrmbuf_inline(), which would cause a crash by accessing "m->m_len".

Add ddb show dpcpu_off command to ease dpcpu memory debugging.
While show pcpu prints pc_dynamic this also prints the original
memory address as well as the maths.
Once dpcpu goes NUMA this is considered to help debugging as well.

MFC r196118:
Put minimum alignment on the dpcpu and vnet section so that ld
when adding the __start_ symbol knows the expected section alignment
and can place the __start_ symbol correctly.
These sections will not support symbols with super-cache line alignment
requirements.
