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

Windows provides the `ENABLE_VIRTUAL_TERMINAL_INPUT` flag for TTY input
streams as a companion flag to `ENABLE_VIRTUAL_TERMINAL_PROCESSING`,
which libuv is already setting for TTY output streams.
Setting this flag lets the terminal emulator perform some of the
processing that libuv already currently does for input events,
but most notably enables receiving control sequences that are
otherwise entirely unavailable, e.g. for bracketed paste
(which the Node.js readline implementation added basic support for
in https://github.com/nodejs/node/commit/87af913b66eab78088acfd).
libuv currently already provides translations for key events to
control sequences, i.e. what this mode is intended to provide,
but libuv does not and cannot translate all such events.
Since the control sequences differ from the ones that Windows
has chosen to standardize on, and applications may not be expecting
this change, this is opt-in for now (but ideally will be the default
behavior starting in libuv v2.x, should that ever happen).
Another downside of this change is that not all shells reset
this mode when an application exits. For example, when running a
Node.js program with this flag enabled inside of PowerShell in
Windows terminal, if the application exits while in raw TTY input mode,
neither the shell nor the terminal emulator reset this flag, rendering
the input stream unusable.
While there's general awareness of the problem that console state is
global state rather than per-process (same as on UNIX platforms),
it seems that applications like PowerShell aren't expecting to need to
unset this flag on the input stream, only its output counterpart
(e.g. 4e7942135f/src/Microsoft.PowerShell.ConsoleHost/host/msh/ConsoleHost.cs (L1156)).
Hence, `uv_tty_reset_mode()` is extended to reset the terminal
to its original state if the new mode is being used.

Extend uv_fs_utime, uv_fs_futime and uv_fs_lutime to accept NAN and
INFINITY, with NAN meaning "don't touch the timestamp" and INFINITY
meaning "set to the current timestamp."
Ugly, but it avoids having to add uv_fs_utime2, etc.
UV_FS_UTIME_NOW and UV_FS_UTIME_OMIT constants have been added to make
it more palatable.

On macOS, when calling `spawn`, the child process's stdio buffer
size is 8192 bytes. This is due to the AF_UNIX socket buffer size
being 8192 bytes in the XNU kernel.
When large amounts of data are transferred through the child
process's stdio, this buffer size can cause performance issues.
To mitigate this, the buffer size has been increased to 65536
bytes, aligning it with the behavior on Linux.
The CreateProcess API on Windows is still not longPathAware,
even if the process itself is. So, if the cwd used for CreateProcess
is too long, then the call fails with a 'INVALID_DIRECTORY' error.
To deal with this, check the length of the cwd and shorten it if it
is longer than MAX_PATH.
Said symbols are not by default available on Windows Server 2016 but
libuv can still use them when
api-ms-win-core-processthreads-l1-1-3.dll is present.

Add a version of uv_udp_try_send that can send multiple datagrams.
Uses sendmmsg(2) on platforms that support it (Linux, FreeBSD, macOS),
falls back to a regular sendmsg(2) loop elsewhere.
This work was sponsored by ISC, the Internet Systems Consortium.
Shuffle around and DRY the sendmsg logic in preparation for
uv_udp_try_send2(). NFC barring bugs.

io_uring support was default-disabled because of numerous kernel bugs
but those are all in the sqpoll (file i/o) parts of io_uring.
Batching of epoll_ctl calls through io_uring works fine, is a nice
optimization, and is therefore unconditionally enabled again.
The UV_USE_IO_URING environment variable now only affects sqpoll, and
only when the UV_LOOP_ENABLE_IO_URING_SQPOLL event loop flag is set.

Libuv looks for "Processor" in /proc/cpuinfo but it's been reported
that on at least some Raspberry Pi models, it's called "model name".
Look for both.

Upgrade GHA image to Ubuntu 24.04 and use the distro-provided qemu.
It should not be necessary anymore to install qemu from .deb because
the stock qemu is new enough in 24.04.
`uv_thread_setname()` sets the name of the current thread. Different
platforms define different limits on the max number of characters
a thread name can be: Linux, IBMi (16), macOS (64), Windows (32767),
and NetBSD (32), etc. `uv_thread_setname()` will truncate it in case
`name` is larger than the limit of the platform.
`uv_thread_getname()` gets the name of the thread specified by `tid`.
The thread name is copied into the buffer pointed to by `name`. The
`size` parameter specifies the size of the buffer pointed to by `name`.
The buffer should be large enough to hold the name of the thread plus
the trailing NUL, or it will be truncated to fit.
