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.

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.

Define constants for the end of the ranges that exist within the
settings BAR so we can use the range syntax in the match instead of
manually checking against the start and end.
This uses inclusive range (..=) syntax, since exclusive range pattern
syntax (..) is experimental. Therefore, each range has a `_LAST`
constant that is equal to the address of the last valid byte in that
range (first + size - 1).
Rewriting the matches in this way allows us to clean up the two clippy
ignores and makes the code a bit easier to read.

On Unix, instead of getting random data from `/dev/urandom`, it will get
it from the `rand` platform agnostic crate instead.
OsRng.fill_bytes on unix will make a syscall to getrandom(2) if
available, otherwise it will read from `dev/urandom` after a succesful
poll to `dev/random`. Regardless of which way a random data is
retrieved, if the entropy pool is not intialized, `fill_bytes` will
block until it is intialized. This shouldn't be a problem because it is
a one time cost.
This CL will also upstream the Windows implementation of the rng device.

When a usb device is attached to guest kernel, guest kernel will
Try to set the usb configuration to value returned by
usb_choose_configuration. Unless the device has multiple configurations
and host side set it before attach to guest os, it will be same value
as what host kernel would set it during initialization. This would casue
a device reset and for Android devices in adb mode it will cause a
disconnect and reconnect.
Also we should allow user space trying to reset the device by setting
device configuration to active configuration.

An optional performance optimization that almost completely avoids the
wakeup cost of timer-based fence polling when all RutabagaComponents use
async_fence_cb. There is still a small overhead from the per-loop
virtio_gpu.needs_fence_poll() tests. This overhead will be removed in
later CLs, when timer-based fencing support is removed.

Adds another method for fencing where a rutabaga component may provide
an asynchronous callback for fence completion. When this method is
enabled, fences no longer need to be polled on the main thread.
When async_fence_cb is enabled, optional polling still occurs for
Rutabaga Components that still rely on it for other purposes (e.g.
virglrenderer for GL query checking).
Both the old and new methods of fence handling are supported with this
CL; e.g. timer-based polling and async callback, but timer-based polling
is the only one active. Follow-up CL(s) will switch to using the async
callback for each RutabagaComponent. Support for the old timer-based
polling will be removed after the async callback method stabilizes in
production.
Also, use a BTreeMap rather a HashMap since we only expect a dozen or so
entries at most. In such cases, a BTreeMap is faster.
* v1 (lfrb@collabora.com): remove all polling + add async_cb
* v2 (ryanneph@google.com): re-introduce optional polling to fix
virglrenderer that relies on it for GL query checking.
* v3 (ryanneph@google.com): replace timer-based polling with
eventfd-based poll() signaling for components that want to use it.
* v4 (ryanneph@google.com): add async fence handling beside timer-based
polling to support both for a short time.
This is a pseudo-reland of commit
a999284da2, but modifications have been
made to support both fencing methods simultaneously.

The queue size defines the number of available descriptors, that can be
used for exchanging messages between guest and hypervisor. Each
virtio-video command uses at least 1 descriptor (eg. CMD_QUEUE uses 2).
The amount of descriptors in use depends on the number of sessions and
buffers in input and output video queue.
In the worst case scenario the peak number can reach over 672 for 8
simultaneous streams, with 26 + 16 buffers each just for CMD_QUEUE
commands alone.
If the entire queue is overfilled with CMD_QUEUE for OUTPUT queue only,
the driver has no free descriptors for INPUT queue buffers. This leads
to encoder/decoder starvation, hence no OUTPUT buffer can be produced
and no CMD_QUEUE will finish, which leads to dead locking the device.
This patch increases the queue size with consideration of above details
with some headroom to avoid driver's deadlock.

Usually a TBT dock has one pcie switch and one or more pcie endpoint device
which connect to pcie switch's downstream port, when such TBT dock is hotplug in,
crosvm will find the first pcie endpoint device, passthrough it into guest and
put it under virtual pcie root port in guest, as one pcie root port could
connect one device only, This means only one pcie endpoint device could work
in guest now.
In order to let all the TBT dock's pcie endpoint devices work in guest, virtual
pcie switch is needed. But virtual pcie switch need more development work, as a
short solution, this commit mark all the pcie endpoint devices as multi pci
function device, then all of them could connect to one virtual pcie root port.
This commit do the following three things:
1. Search all the pcie endpoint devices under host pcie root port.
2. Record all the pcie endpoint devices attached to virtual pcie root port,
so that they could be removed in hotplug out.
3. Allocate pci function number to all the pcie endpoint devices.

A previous commit moved the creation of the executor for the vhost-user
device processes before the minijail jail_and_fork() call, and the file
descriptor of the executor was not marked for preservation when entering
the jail, so running the vhost-user-fs device would result in errors
like this:
[WARNING:cros_async/src/sys/unix/uring_executor.rs:343] Failed to
submit NOP for waking up executor: Failed to enter io uring: 9
This is because the io_uring context file descriptor was no longer
valid, so uring system calls would return 9 (EBADF).
Add AsRawDescriptors implementations to UringExecutor and FdExecutor so
we can preserve the fd across the minijail fork.
Other vhost-user devices were not affected because they don't enter a
jail; the fs device requires this so it can do uid/gid remapping.
