Remove Giant from /dev/mem and /dev/kmem. It is definitely not needed for i386, and from the code inspection, nothing in the arm/mips/sparc64 implementations depends on it.

Add new privileges, PRIV_KMEM_READ and PRIV_KMEM_WRITE, used in opening /dev/kmem and /dev/mem (in addition to traditional file permission checks). PRIV_KMEM_READ is different from other PRIV_* checks in that it's allowed by default.

Break out the MI part of the /dev/[k]mem and /dev/io drivers into their own directory and module, leaving the MD parts in the MD area (the MD parts _are_ part of the modules). /dev/mem and /dev/io are now loadable modules, thus taking us one step further towards a kernel created entirely out of modules. Of course, there is nothing preventing the kernel from having these statically compiled.
