026f72f9fb enable core scheduling regardless of enabled features
Now that core scheduling has been upstreamed, it can be enabled for all
platforms. This change keeps the Chrome OS version as a fallback if the
chromeos feature is enabled.

This change was patterned after http://crrev.com/c/2896464.

9af97d72fa [base] update/clean mmap interfaces.
This CL addresses some minor issues with the existing interface:
1. from_descriptor is too generic for some platforms that require
   special handling for file/File backed mappings.
2. Nearly all call sites pass either File or SharedMemory. Now
   we just have from_ methods for those types to preserve type
   information.
3. Other platforms require additional fields in MemoryMapping, so a
   tuple struct no longer makes sense.
4. The mmap syscall error message was misleading as we use it for more
   than just the mmap syscall.

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.

6a0960a4a7 base: First steps towards universal RawDescriptor
This involves removing RawFd trait implementations from
Event and Timer, and resolving the echoing dependencies from
there.

Ultimately, this results mostly in changes across ioctl
(new thin layer in base), kvm, msg_on_socket, and a few other
areas. As usual, most changes are negligible.

e392c46953 base: Add WaitContext
This is a layer above PollContext with a more generic interface.
As PollContext is used so widely, this is quite a large change
in order to accomodate the interface update, especially with the
use of RawDescriptor. In some cases this has caused an echo
of updates to RawDescriptor, which is fine because of our eventual
goal to move the whole codebase to it regardless.

Note there are a few instances of forcing the RawDescriptor update
chain to stop, ex. ioctl. This is to keep the scope of this CL
concentrated and avoid changing entire other areas.

Note that this CL leaves out a few additional pieces of work:
 - The sole usage of EpollContext over PollContext (event_loop),
which poses a bigger challenge for interface changes
 - Full PollToken renaming, which is a tiny change turned difficult
due to the unavailability of type aliases for traits.
 - Renaming certain methods which have been updated to use
RawDescriptor such as keep_fds. Some have enough dependencies that
they are worth avoiding to keep this CL pointed, but will be
addressed in future CLs to make sure the whole codebase is on the
fd->descriptor train

685316f0bd base: EventFd -> Event renaming
Note the CL size is large entirely due to the rename,
the changes are mostly negligible.

Also making a few small additional changes in sys_util
areas that don't need much attention in base. This includes
typedefing and adding specific imports for areas that don't
require significant interface changes.

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.
