ac0fc378a3 Fix remaining Chrome/Chromium OS instances
These should be written as ChromeOS and ChromiumOS (without the space)
to match the updated branding. The copyright headers were already
migrated to the new style (https://crrev.com/c/3894243), but there were
some more instances left over.

7fd815ed22 crosvm: switch to upstream tempfile crate
Use the crates.io implementation of tempfile instead of our own version.

Our reimplementation is kept in the tree for now in case of dependencies
outside of the crosvm tree; it can be removed later once those are fully
switched over to the crates.io implementation.

eff60328c1 Add a From impl for async errors to io::Error
Sometimes users of cros_async need to return an io::Error.  Provide a
conversion function to convert the various async errors into an
io::Error.  This allows callers to access the underlying error without
forcing us to expose these internal implementation details.

1fcc8a8f3c io_uring: Make UringContext Sync
Rather than requiring callers to wrap the entire UringContext in a big
lock, make UringContext Sync by internally using fine-grained locks:

* The submit queue is wrapped with a Mutex so that threads may still add
  operations to the submit queue even when a thread is blocked
  inside an io_uring_enter call.
* The completion queue internally uses a Mutex around the pending op
  data and completed count so that two threads don't end up trying to
  remove the same operation from the completed queue.

With this we can enable the await_uring_from_poll test.  This test
uncovered missing wakeups in the case where a uring operation is added
from one thread while the main uring thread is blocked inside an
io_uring_enter syscall. To deal with this, we call submit() whenever the
pending operation is polled and not yet submitted.

b3fca20e24 Refactor cros_async interface to avoid RawFd.
Instead of creating IoSourceExt from AsRawFd implementers, we've
switched to creating from a marker trait `IntoAsync`. This lets us use
other types like RawDescriptor easily with this crate.  By using the
marker, we also provide some type safety by requiring consumers of
IoSourceExt to declare that their type is expected to work with async
operations. This way we can provide stronger guarantees that an async
IO trait object will behave in a reasonable way.

This CL also purges the cros_async -> base and io_uring -> base
references, and provides the base types needed to add new async
primitives to base.

6b19695c81 Add "base" crate and transition crosvm usages to it from sys_util
For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

a9a1d02277 Add io_uring interfaces
Provide a low-level interface to operating the new io_uring interface.

This is an unsafe interface with the basic operations of setting up the
ring, adding to it, removing from it, and polling it.

This will be followed by a safe interface layer on top of this code,
then by additions to the asynchronous executor that allow for
asynchronously doing multiple operations to files from one context.
