The mmaps made through the sys_util API are usually for guest memory or
other large shared memory chunks that will pollute the file system with
huge dumps on crash. By using MADV_DONTDUMP, we save the file system
from storing these useless data segments when crosvm crashes.

This really should have been added along with the poll timeout support,
which changed the syscalls used in every jailed device.

crosvm spawns a lot of processes/threads, and having these all use the same
name as the original process can be confusing. So at least in the instances
where Rust threads are spawned (vs. minijail_fork()), use a thread::Builder
to allow setting the thread name.
BUG=none
TEST=start crosvm, check thread names with top

This adds the virtio wayland device which is activated by default. The wayland
device needs the XDG_RUNTIME_DIR env variable to be set and a running wayland
compositor to connect to in that directory.
