f3a874157c base: windows: update protection to fix build breakage
Change http://crrev.com/c/3737406 removed the custom permission enum for
IOMMU, but did not update the related Windows code. This results in a
build error that was not caught because the Windows builder was
temporarily deactivated.

2689c838af base: simplify Clock/FakeClock API
Clock now has a single now() function that returns a std::time::Instant
rather than wrapping an Instant itself.

FakeClock provides the same now() API, except the Instant it reports is
only advanced when test code calls add_ns(). FakeClock continues to
provide the add_event() and add_ns() APIs used by tests.

The only functional difference is that the epoch used by FakeClock is
now whatever moment in (real) time it is created, rather than a fixed
timestamp, but this should not change the results of the tests. The only
way to observe the contents of an Instant is by comparing it to other
Instants, which should all be derived from the Clock/FakeClock now()
API.

98fcb96d6b Cargo: bump all rand dependencies to 0.8
The previous configuration made us pull in three different versions of
rand, and depending on "*" is a recipe for API incompatibility.

crosvm-fuzz needs to match its rand version to the rand_core used in
common/cros_fuzz, so that will be upgraded separately.

e5c6e65731 devices: pit: remove clock_gettime() usage
The original Pit code encoded the start value of a timer into the
count_load_time field as a number of nanoseconds since the start of
the host's monotonic time value. Instead, we can use the PitCounter's
creation_time as the epoch. This makes the math look a bit more sensible
and removes the use of the non-portable clock_gettime() function.

Before
======

get_channel_state():
    count_load_time = get_monotonic_time() - start.elapsed()
=== count_load_time = now() - (now() - start)
=== count_load_time = start

set_channel_state():
    start = now() - (get_monotonic_time() - count_load_time)
=== start = now() - now() + count_load_time
=== start = count_load_time

After
=====

get_channel_state():
    count_load_time = start - creation_time

set_channel_state():
    start = creation_time + count_load_time

19fc097eb8 crosvm: replace lazy_static with once_cell
We depend on both lazy_static and once_cell, which do basically the same
thing.

The once_cell crate has a few advantages:
- once_cell is on track to be included into libstd.
  (https://github.com/rust-lang/rust/issues/74465)
- once_cell doesn't require macro magic.

Replace the uses of lazy_static with their once_cell equivalents so we
don't need to pull in both crates.

3e8054ee7c base: unix: merge EpollContext into PollContext
The main distinction between PollContext and EpollContext was that the
latter was safe to use from multiple threads. This was not true of the
more widely-used PollContext for two reasons:

1. The `events` array was stored inside the `PollContext` structure,
   whereas `EpollContext` required the caller to pass their own storage
   for events.
2. `PollContext` had a hangup detection feature used to debug busy
   looping cases that result from a failure to remove hungup file
   descriptors from the context.

Point 1 is resolved by returning a `SmallVec` of events that avoids
allocation for the normal case (and in fact it should avoid allocation
in all cases on Linux, where the maximum number of events returned from
a single `epoll_wait()` call is limited to the same size as the
preallocated `SmallVec`). This simplifies the API and also means that
there is no need for per-context storage.

Point 2 can't easily be resolved, since it would require the `wait` call
to mutate shared state (this could be done by adding a mutex around the
shared data, but that seems like too much overhead for the value of the
feature). Instead, this patch just removes the hangup detection code.

569a58490e base: clarify SharedMemory API
When creating shared memory, 'name' can have one of two meanings. It
could either be a debugging tag with no semantic meaning, or it could
uniquely identify a shared memory object within some namespace. Linux
memfd uses name in the first meaning, whereas Windows (and Linux shm)
uses it in the second meaning.

Currently, crosvm has no use cases for the named shared memory of the
second type, so it is not supported. Make it clear that the SharedMemory
APIs treats name as a debugging-only name. Remove the "anon" and "named"
constructors, since they had no semantic meaning. Also require a name
when constructing a SharedMemory, since there's no reason not to provide
one to make debugging easier.

The only semantic change is setting the name of GuestMemory's underlying
shmem to "crosvm_guest", which it was until recently. This fixes some
ManaTEE tests which use the name to determine CrOS guest memory usage.

aa2e59d82f base: improve documentation of Descriptor and AsRawDescriptor
Although it can be useful for some limited cases, the Descriptor wrapper
class should ideally be eschewed and an alternative based on
implementing AsRawDescriptor on the right type be preferred. Make sure
its documentation reflects that.

The reason for avoiding Descriptor is that it encourages storing raw
descriptors that can possibly be closed before the user expects it. A
reasonable alternative to doing this is to call as_raw_descriptor() at
the exact moment the descriptor is needed, and never storing the result
- this ensures that the providing object (and underlying descriptor)
remain alive for long enough. Update the documentation of
AsRawDescriptor to explain and hopefully encourage this practice.

Fix some compatibility issues in crosvm to allow it compile against

- Ioctl numbers are ints like bionic, not unsigned long like glibc.
- The sched_param struct has extra fields that must be initialized, zero
  initialize the whole struct.
- libc::pthread_t is void* and doesn't match std::os::unix:🧵:RawPthread,
  it needs a cast.
- Some msghdr and cmsghdr fields are u32 instead of usize.
- cmsghdr has an extra __pad1 fields that must be initialized, zero initialize

- msghdr has private __pad1 and __pad2 fields that cannot be initialized,

dealing with expanding and releasing memory from `virtio-balloon`.

For windows based hypervisors, balloon expansion triggers OS interaction
with reclaiming memory pages, which is automatically managed in KVM.
Similarly, a balloon deflation will cause OS interaction for releasing
memory back to the OS.

Update the error return for `remove_mapping` when `madvise` call fails.

The unix clock uses crate::Event. Using crate::Event makes it
consistent and downstream compiler happy.

273a9b16b3 base: move timerfd to timer
A series of patches move unix specific code into src/sys/unix/timer.rs,
retain platform independent code in src/timer.rs and then introduces

fd71fa1bd4 crosvm: refactor base::syslog and integrate with log facade
Motivation behind this is to greatly reduce code duplication and more
streamlined syslog experience.
Integration with log facade allows us to have logs from 3rd party crates
and better integration into rust ecosystem. As well as getting rid of
our log/warn/etc macros.

Notable changes:
    * Moving to log's levels: info/trace/debug/error/warn. Note that
      none of our code utilizes alert/critical/etc so this is benign
    * Moving windows' syslog implementation filtering into
      cross-platform scope;

BUG=none

a81eebfe8e cros_async: move IntoAsync to use AsRawDescriptor
Originally cros_async was not permitted to depend on base, and as such
was precluded from using RawDescriptor/AsRawDescriptor. Now that we can
use base, we are switching over to those types/traits as they allow for
much cleaner cross platform code.

68bbe92339 cros_async: upstream Windows support.
Major changes:
* Adds Windows implementations
* Refactors cros_async to use the styleguide for cross platform code.
* Adds platform specific Descriptor impls to Timer & Event (short term;
  this will go away in the next CL in the series).

Minor adjustments:
* The doctests for the Executor were passing the wrong type of seek
  parameter to write_from_vec. It was disabling seeking (None) when it
  should have been  seeking to zero (Some(0)).

1def2e61d9 reland: Remove temporarily duplicated code from codebase
This removes sys_util(_core), which moved into base::unix/common, as
well as common/(cros_async,io_uring), which moved into the root
directory.

The only reason the code was still around is that they were still
used in the ChromeOS codebase.
ChromeOS has pinned the version of crosvm it uses for these libraries
so we can go ahead and remove the code.

A few remaining references to sys_util have been updated to base.
