Support alignment requirements for a 64 bit kernel.

We introduce both a user alignment and a kernel alignment. These are
separate requirements since for 64 bit with a 32 bit kernel we need to
ensure the kernel can consume messages that are 8-byte aligned. This
change removes any possibility of undefined behavior and also allows the
kernel to support 64 bit RPCs for the userland.

A lot of the code that performs alignment was simplified under the
assumption that the message headers are well aligned. To enforce that
going forward, a few static assertions were added.
