Distinguish between errors and "the console title is the empty string"
when calling GetConsoleTitle. Both are signified by a return value of
zero.
No test because I couldn't think of a succinct way to programmatically
create a new console window with an empty title.

Implement `uv_tcp_keepalive_ex` function that extends
`uv_tcp_keepalive` to support `TCP_KEEPINTVL` and `TCP_KEEPCN`
socket options in addition to TCP_KEEPIDLE.
The documentation is referring to an internal name -
UV_LOOP_ENABLE_IO_URING_SQPOLL - in several places. Fix this by using
the public UV_LOOP_USE_IO_URING_SQPOLL name instead.
Handle out-of-memory conditions in uv_loop_init better, albeit still
not perfect: bubble up the error instead of aborting.
Also fixes a file descriptor leak on Linux (and likely other platforms)
that the new test caught; the backend epoll fd was being leaked in the
error path.

I changed the default stack size in commit 73b0c1f94 from October 2022
and although I added a versionchanged note, I didn't update the blurb
a few lines below.
It wasn't accurate before that change either though, because even with
musl libc's ~80kb thread stacks, 128 threads works out to 10 MB.

Haiku has parallel types to stdint.h, and their APIs use these
types. In the Haiku-specific haiku.h file, it is passing an
address of a uint32_t to get_cpu_topology_info(), that expects
the other uint32:
648fa5897c/src/system/libroot/os/system_info.cpp (L187)
You get an "incompatible-pointer-types" warning in gcc if the
warnings are turned up. But if you pass the pointer to Haiku's
notion of uint32, then the warning goes away.
On some platforms (like GNU/Hurd), `getsockname` returns an empty
string for sockets in the UNIX domain. However, we do have stored the
path info in `pipe_fname` of `uv_pipe_t`, so we can try with it
if `getsockname` returns an empty string.
Use fchmod() on platforms that support it on UNIX sockets. Only fall
back to chmod() on platforms that don't (macOS and the BSDs.)
Remove the stat + chmod dance from the fallback and just call chmod
directly, because that's another source of TOCTOU issues.

Documentation on Linux explains that nul bytes have no
special significance in abstract namespace socket names.
Avoid precluding such addresses.

After 14 years that should be fairly safe, right? Right!?
Not safe enough for Windows Server 2016 apparently; there are build
errors coming from system headers. The GHA images are slated for removal
in a month anyway so upgrade them to Windows Server 2025.

In function main, the pointer lib allocated at line 7 is passed as an
argument to functions uv_dlopen at line 10, uv_dlerror at lines 11 and
17, and uv_dlsym at line 16, but it is never freed before the function
returns at line 24. This results in a memory leak bug.
Solaris 11.4 has Load Balancing for SO_REUSEPORT, but setting
SO_REUSEADDR disables load balancing. As per comments in
test/test-udp-reuseport.c prefer SO_REUSEPORT when available.
With these changes in place udp-reuseport testing passes. BIND (named),
which uses routing sockets which cause ENOPROTOOPT to be returned when
SO_REUSEPORT is requested, also continues to work with the change.
Notes:
- The use of getsockopt() to query if SO_REUSEPORT was available was
erroneous.
- Selectively limiting SO_REUSEPORT setting to specific types of socket
was considered but not entertained.
- Oracle will investigate if the setting of SO_REUSEADDR was
intentionally meant to prevent load balancing.
- Adding a test for routing sockets is left for future work.
On OpenBSD we do not know the cpuspeed in same cases (mostly arm64)
and the HW_CPUSPEED sysctl will return EOPNOTSUPP in that case,
which can be ignored because we still need the rest of the CPU
information.
Solaris provides sendmmsg() as of 11.3.32.
It was added at the same time as MSG_WAITFORONE.
The same is seen in Illumos guarded by __BSD_VISIBLE
