5bbbf61082 lint: Resolve the easier clippy lints
Hopefully the changes are self-explanatory and uncontroversial. This
eliminates much of the noise from `cargo clippy` and, for my purposes,
gives me a reasonable way to use it as a tool when writing and reviewing
code.

Here is the Clippy invocation I was using:

    cargo +nightly clippy -- -W clippy::correctness -A renamed_and_removed_lints -Aclippy::{blacklisted_name,borrowed_box,cast_lossless,cast_ptr_alignment,enum_variant_names,identity_op,if_same_then_else,mut_from_ref,needless_pass_by_value,new_without_default,new_without_default_derive,or_fun_call,ptr_arg,should_implement_trait,single_match,too_many_arguments,trivially_copy_pass_by_ref,unreadable_literal,unsafe_vector_initialization,useless_transmute}

TEST=cargo check --features wl-dmabuf,gpu,usb-emulation
TEST=boot linux

45753529ba x86_64: Set EFER.LMA
We were setting LME (Long Mode Enabled) but not LMA (Long Mode Active).
New kernels have a check in the kvm code that disallows this brokenness.

1aa03e00a0 x86_64: implement error trait for sub-modules in x86_64 crate
Implement the std::error::Error Trait for Error types within the
x86_64 crate.  We will make use of these implementations later on when
we are using the architecture Trait to pass architecture-specific
errors up with meaningful descriptions.

4567a281a5 crosvm: disable reliance on support of 1GB pages
The initalization code in crosvm used two-level page table
    in long mode, with last entry covering 1GB. This assumed
    presence of 1GB pages support ('pdpe1gb' in /proc/cpuinfo).
    Some CPUs don't have it.

GuestAddress.

b2ae5fabd3 x86_64: Remove extra closure args and double-derefs
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.

d4eaa4056f sys_util: Add guest_memory
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.
