Macros were previously imported through `#[macro_use] extern crate`,
which is basically a glob import of all macros from the crate. As of
2018 edition of Rust, `extern crate` is no longer required and macros
are imported individually like any other item from a dependency. This CL
fills in all the appropriate macro imports that will allow us to remove
our use of `extern crate` in a subsequent CL.

Found by running: `cargo rustc -- -D bare_trait_objects`
Bare trait objects like `&Trait` and `Box<Trait>` are soft-deprecated in
2018 edition and will start warning at some point.
As part of this, I replaced `Box<Trait + 'static>` with `Box<dyn Trait>`
because the 'static bound is implied for boxed trait objects.

The default panic hook prints panic information and a backtrace to
stderr, where it gets dropped into /dev/null in the typical crostini
context.
This change adds a panic hook that will call the default panic hook
with stderr redirected to a pipe, which will then get forwarded to
syslog.
The new hook also forces an abort at the end to ensure the crash
reporter sees the panicked crosvm process, which will generate a
minidump for later debugging.
TEST=manually add panic!() observe /var/log/messages
