eb3b49f185 gpu_display: better detection for window sizing/moving modal loop.
We do receive WM_ENTERSIZEMOVE when the window is about to be resized or
moved, but it doesn't tell us whether resizing or moving should be
expected. We won't know that until later we receive WM_SIZING or
WM_MOVING. There are also corner cases where we don't receive either
WM_SIZING or WM_MOVING in the modal loop, or receive both of them.

This CL adds an enum SizeMoveLoopState to track this state, so that we
can know whether the window is resizing or moving.

One alternative is to use WM_NCHITTEST to test whether the cursor is on
the window title bar (which implies moving the window) or window
borders/corners (which implies resizing) when WM_ENTERSIZEMOVE is
received. However, the user may also trigger resizing/moving from the
system menu (e.g. by right-clicking on the title bar and selecting it
from the drop down list), so this is not always reliable.

3b2ecd9570 gpu: a few fixes for Windows build.
1. gpu_control_tube is not used on Windows yet. We will make use of
   it and test it in the downstream first before removing the Unix
   feature flag.
2. In Gpu::keep_rds(), skip appending descriptors of stdout and
   stderr since it is hard to find such descriptors on Windows, and
   this function won't be called on Windows anyways.
3. Some functions in gpu_display should be guarded with gfxstream
   feature flag, since we don't need to link against gfxstream
   binary when we are building/tesing without gfxstream.

We were busy-waiting on atomic variables for the message loop

don't start posting messages to the WndProc thread until the
latter has created the message queue and is about to enter the

thread notifies other threads that it is ready by sending out its
thread ID.

b97f10ef0f gpu_display: upstream Windows implementation
On Windows, we have to create a GUI thread that creates the window and
retrieves window messages from the thread-specific message queue created
by the system. All host events, such as window resizing and mouse and
keyboard events, are sent in the form of window messages. Hence, we
created these structs/traits to model it:

- `Window`: Owns the handle of one window, and provides helper functions
  for operating on this window.
- `HandleWindowMessage`: A trait implemented by the struct that
  processes host events. In our case, that is the surface.
- `WindowMessageProcessor`: Holds one `Window` object and one
  `HandleWindowMessage` trait object. We only support one window for
  now. Once we support multi-windowing, there will be multiple
  processors.
- `WindowMessageDispatcher`: A singleton, responsible for dispatching
  messages retrieved from the message queue to the targeted processor.
- `WindowProcedureThread`: Wraps the GUI thread, retrieves messages from
  the message queue and forwards them to the dispatcher. It also
  provides helper functions for other threads to talk to the GUI thread.
- `MessageRelayThread`: Relays service messages to the GUI thread.

Main difference from other platforms: event devices are imported to the
GUI thread, since all host events are processed there.

256ac75f1f Revert "x display: ST event emulation for MT events"
This reverts commit d98f01af14.

NOTE: we are intentionally keeping the changes to use new tracking IDs
per contact, and the conversion of wayland to send MT events, as those
are not really part of the simulation change, and should be fine to keep.

Following discussion w/ drmasquatch@ offline re comments on the OCL, it
seems like there are other ways we could solve for the original
problem without introducing a simulation layer. Given the complexity
introduced and the fact that not all consumers necessarily want this
compat layer, a revert seems like the best step. Some options for fixing
the original problem in the future:

* Modify gpu_display_wl to produce ST events based on a CLI flag.
  This is pretty easy, and involves enhancing
  `--display-window-mouse` to take whether the events should be ST
  or MT, and then generating the ST events in the display backends
  as specified. The same flag also needs to create a ST device
  rather than a MT device so that the ST events will be accepted
  by the guest kernel.
* Modify the virtio-input kernel driver. This might be the right
  place to add a compat layer, if one is needed more broadly. It
  will also fix the problem everywhere.

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.

38fedb73e5 Revert "vm_memory: Add from_desciptor() in MemoryMappingBuilder"
If we need descriptor for things that aren't file or other shared_memory objects, we can create a separate descriptor change, but it shouldn't be the default.

This reverts commit 533c5c8258.

Reason for revert: this causes conflicts with other platforms.

Original change's description:
> vm_memory: Add from_desciptor() in MemoryMappingBuilder
>
> MemoryMappingBuilder had `from_file()` and `from_shared_memory`, which
> are almost the same. So, this commit adds `from_descriptor()` to replace

114d7d7ccd gpu_display: Add opt wayland ext for sending scanout id
Cuttlefish's streaming server, which acts as a Wayland compositor
in order to receive display framebuffers from Crosvm, needs some
mechanism to tell which Wayland surface corresponds to which display
(a "display" is a "scanout" in virtio-gpu terminology).

Wayland object ids can not be directly used for this as all Wayland
objects share a single global id space (so the first created Wayland
wl_surface surface object may have id = 15).

Previously, the case of unchanging displays was handled by enforcing
the creation order of surfaces within Crosvm so that Cuttlefish's
streaming server (which is a Wayland compositor) could assume the
creation order corresponded to the display order. However, this still
experienced issues (b:186580833) when surfaces were destroyed and
later recreated when handling `set_scanout(..., resource_id = 0)`
commands.

There is also an ongoing effort to support adding and removing
displays at runtime in (see aosp/1671968) which experiences the
same issue. When surfaces are arbitrarily created and destroyed,
Cuttlefish's streaming server has no way to determine which Wayland
surface corresponds to which display.

To solve all of this, this change introduces an extension to allow
Wayland clients (Crosvm) to attach additional metadata (scanout_id)
to Wayland objects (surfaces) so that Wayland compositors (Cuttlefish's
streaming server) can exactly determine which surfaces correspond
to which displays. I will attempt to upstream this protocol (tracked
in b:191901112).

bb95fc4512 gpu_display/wayland: Added keyboard and pointing devices
Added preliminary version of keyboard and pointing device routine
for wayland implementation. The pointing input is wired as a multi
touch device. Due to the fact that wayland client is callback based,
all the necessary incoming events are serialized and stashed in the
temp circular buffer and then processed afterwards from the main event
loop.

Known issues:

1. Mouse input can't be properly wired inside the guest as a mouse
   device without pointer locking, but this is not what we want. The
   approach emulates it as a multitouch device, but, of course, it
   implies limitations in functionality.  Limitations include cursor
   in the VM that doesn't move in unison with the host cursor.

2. I kept the mouse cursor surface since it's not decided yet which
   approach for handling pointing input device will be used (see #1).

   Removing the mouse surface in the guest would remove the lagging
   guest cursor.  The alternatives to the multi-touch device are:

   "- Relative mice (e.g. a typical PC mouse). These are relative
      devices, meaning they send deltas from the current cursor
      position.  Some apps like games rely on these events.

    - Touchscreens (multitouch, single touch). These are absolute
      devices, and are much easier to implement seamless guest/host
      input for.

    - Touchpads (these are absolute devices). I'm not sure these are
      really compelling for any use case." -nkgold@

3. This code is for POC purpose only, so there are still lot of minor
   issues and negligence in it.

Looking forward for your comments and proposals.

41daa354c7 gpu_display: refactor event loop
There is a desire for Wayland and possibly other display backends to

backend up to the common layer to prevent duplication.

The common layer also keeps track of surfaces and external memory
objects to make this easier.  The GpuDisplaySurface/GpuDisplayMemory
traits are  introduced in case the common layer needs to perform
compositor specific operation.

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.

d09392e37e uprev rust-toolchain and fix clippy warnings
Some judgement calls were made about unnecessary wrapping. Usually they
would get resolved by removing the wrapping or returning a convenient
error, but the ones that returned results for consistency with other
functions were added to the allow list.

The error handling in the usb code had a lot of unit error types which
is now a clippy lint. This was resolved by either removing the result
entirely or returning a convenient error.

The field_reassign_with_default lint is faulty and was added to the list
of supressions. This affected virtio-wayland code.

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
