This is validated by tests introduced in
59beffb46c etc. This commit alone doesn't fix said
tests, because:
* on this poll, we will alert the waiting async;
* when reselecting, we will still request POLLIN, because the AFD_POLL_READ
request is still active,
* when POLLIN is subsequently signaled, we do not remove it in
sock_dispatch_asyncs(), because we check async_waiting(), not async_queued().

The 'status' field of send_socket_request is always either
STATUS_PENDING or STATUS_DEVICE_NOT_READY, and the 'total' field is
always zero.
Replace the 'status' field with 'force_async' boolean field, and get rid
of the 'total' field entirely.
Also, clean up the send_socket handler code a bit.

Make send_socket alert the async immediately if poll() call detects that
there are incoming data in the socket, bypassing the wineserver's main

For sock_transmit, we always mark the async as pending and set the IOSB

Today, async_set_completion_callback() is used to register a function
that is called when the async I/O is completed. It is assumed that the
async will eventually be queued when such callback is registered.
However, this incurs extra complexity in future code that needs the
completion logic to be invoked even if the async is never actually
queued (e.g. when the I/O failed synchronously before async_handoff).
Generalise async completion callback by calling it in async_handoff()
when the I/O status indicates failure.

Commit 15483b1a12 (server: Allow calling async_handoff() with status
code STATUS_ALERTED., 2022-02-10) introduced the set_async_direct_result
handler which calls async_set_initial_status().
However, the async_set_initial_status() call does nothing since
async->terminated is set, leaving the async in a confusing state
(unknown_status = 1 but pending/completed).
So far, this issue is unlikely to have been a problem in practice for
the following reasons:
1. async_set_initial_status() would have unset unknown_status, but it
remains set instead. This is usually not a problem, since
unknown_status is usually ever read by code paths effectively
unreachable for non-device (e.g. socket) asyncs.
It would still potentially allow set_async_direct_result to be called
multiple times, but it wouldn't actually happen in practice unless
something goes wrong.
2. async_set_initial_status() would have set initial_status; however,
it is left with the default value STATUS_PENDING. If the actual
status is something other than that, the handler closes the wait
handle and async_satisfied (the only real consumer of initial_status)
would never be called anyway.
For reasons above, this issue is not effectively observable or testable.
Nonetheless, the current code does leave the async object in an
inconsistent state.
Fix this by removing the !async->terminated check in
async_set_initial_status().
Also, remove assert( async->unknown_status ). The client can now
trigger the assert() by calling set_async_direct_result on a device
async, thereby causing async_set_initial_status() to be called twice.

If the server detects that an I/O request could be completed immediately
(e.g. the socket to read from already has incoming data), it can now
return STATUS_ALERTED to allow opportunistic synchronous I/O. The Unix
side will then attempt to perform I/O in nonblocking mode and report
back the I/O status to the server via the new server request
"set_async_direct_result". If the operation returns e.g. EAGAIN
or EWOULDBLOCK, the client can opt to either abandon the request (by
specifying an error status) or poll for it in the server as usual (by
waiting on the wait handle).
Without such mechanism in place, the client cannot safely perform
immediately satiable I/O operations synchronously, since it can
potentially conflict with other pending I/O operations that have already
been queued.

Fixes a regression introduced by
5c009c17b3.
For IPV6 socket already bound with bind() with IPV6_V6ONLY set to 0
the address returned by getsockname() may change after it is connected
to a IPV4 peer (e. g., from :: to ::ffff:192.0.2.128).
The effect of blamed commit is that before that Unix getsockname()
was called for each ws2_32 getsockname() and after the commit the
socket name is cached at bind and connect.

Otherwise, async_waiting() returns 0, leading the socket object to
believe that the previous async request has not yet been acknowledged.
This results in I/O hang for subsequent reads (until shutdown).
Also, async_destroy() calls async_reselect() only after removing the
async request from the queue. Make async_set_result() consistent with
this behaviour.

Some PE executables (like mingw's gdb port) just do something like:
- WaitForSingleObject(GetStdHandle(STD_INPUT_HANDLE), INFINITE) and hang
for ever (the read operations are done *after* the wait operation
succeeds)
(of course, the real wait operation is more complex, but the problematic
part boils down to that)
This hangs for ever because conhost's main input thread hasn't been started
yet.

Today, Wine uses NtQueryInformationProcess/ProcessDebugPort to detect
whether the current process is being debugged. If it is, the process
issues a breakpoint to yield control to the debugger.
Some debuggers (e.g. latest CDB) appear to create debug handles with
restricted DACL, which causes querying debug port to fail with
STATUS_ACCESS_DENIED. This results in the debuggee erroneously
skipping the initial breakpoint.
Fix this by not requiring DEBUG_ALL_ACCESS when opening the debug port
object. Instead, use MAXIMUM_ALLOWED for the access mask.
