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.

Ideally we should be using sock_get_poll_events() and sock_poll_event() instead,
but that seems like an overly risky change for this late in code freeze.

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.

FreeBSD 14-CURRENT got the non-standard sched_setaffinity() function, but
it uses FreeBSD's cpuset_t type instead of Linux's cpu_set_t (also
non-standard). This breaks the build. We have to define _WITH_CPU_SET_T
before including <sched.h> to get that type named cpu_set_t instead.
