The table grew with the addition of the 16 mpc_intsrc structures.
Correct the `compute_mp_size` function, the end check, and add a unit
test for the not having enough memory.

The mptable inherited from kvmtool had some missing pieces. On top of that,
crosvm does not use KVM_SET_GSI_ROUTING. The addresses makes mptable match
the default routing in host kernel and removes "noapic".
TEST=cargo build (--release). tatl boot tested on 4.4.0 and 4.4.9

Mutable references being declared mutable themselves is unnecessary and
now generates a warning.

Not all types are safe to read from guest memory. Any type with a
reference or pointer will be initialized to random bits that don't refer
to a valid address. This can cause dangling pointer and general
unsafe behavior.
To fix this, limit types that can be read with read_obj to those that
implement the unsafe trait `DataInit`. Provide implementations of
`DataInit` for intrinsic types that are obviously safe to initialize
with random data.
Implement the needed traits for bootparam types as they are read from
the kernel image directly.

A few places were passing a reference to a reference, which just gets
compiled out anyways.
Some other places where passing `|e| ErrorName(e)` as a closure when
just `ErrorName` would be more succinct.

Add a module for accessing guest memory.
This module will replace all the slices that are used to access it
currently as those slices aren't valid because the memory is volatile
and a volatile slice doesn't exist in rust.
Modify the existing users so they no longer depend on the deprecated slice
access.
