The advantage of seqpacket is that they are connection oriented. A
listener can be created that accepts new connections, useful for the
path based VM control sockets. Previously, the only bidirectional
sockets in crosvm were either stream based or made using socketpair.
This change also whitelists sendmsg and recvmsg for the common device
policy.

I have been running into Debug-printed error messages too often and
needing to look up in the source code each level of nested errors to
find out from the comment on the error variant what the short name of
the variant means in human terms. Worse, many errors (like the one shown
below) already had error strings written but were being printed from the
calling code in the less helpful Debug representation anyway.
Before:
[ERROR:src/main.rs:705] The architecture failed to build the vm: NoVarEmpty
After:
[ERROR:src/main.rs:705] The architecture failed to build the vm: /var/empty doesn't exist, can't jail devices.

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:

Instead of using unaligned memory. Allocate aligned memory and copy into it, we
were already doing an clone. There should be no overhead for this new
approach.
