156cea0d43 sys_util: Fix all the default clippy warnings
Fix following warnings so that cargo clippy passes under sys_utils:
* new_without_default
* wrong_self_convention
* or_fun_call
* comparison_chain

Note that we still have warnings on other targets such as --tests.

e33b55c429 tempfile: Unify the two tempdir implementations
Looks like we ended up with two totally different tempdir
implementations: one from CL:520706 and the other from CL:1409705.

This CL consolidates them into one implementation.

da52468b34 tempfile: reimplement using libc::mkdtemp
POSIX provides a standard mkdtemp() function to securely create a
temporary directory; use it rather than reinventing the wheel.

This also drops the dependency of tempfile on rand_ish, which will allow
easier use of the tempfile implementation outside of crosvm.

aecf9a4dee edition: Remove extern crate lines
In Rust 2018 edition, `extern crate` is no longer required for importing
from other crates. Instead of writing:

    extern crate dep;
    use dep::Thing;

we write:

    use dep::Thing;

In this approach, macros are imported individually from the declaring
crate rather than through #[macro_use]. Before:

    #[macro_use]
    extern crate sys_util;

After:

    use sys_util::{debug, error};

The only place that `extern crate` continues to be required is in
importing the compiler's proc_macro API into a procedural macro crate.
This will hopefully be fixed in a future Rust release.

    extern crate proc_macro;

fd67ec5ffc protos: Update to protobuf 2.3
This matches the version already used by crostini_client.

The newer protobuf version depends on the tempfile crate rather than
tempdir, the latter being now deprecated. So I replaced our immitation
tempdir crate with one that matches the API of tempfile instead. As a
reminder, we use this crate as a patch to avoid pulling in all of the
rand crate and its many dependencies.
