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.

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.

`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.
This commit introduces the `uv_thread_detach` for thread detaching,
allowing threads to be detached state on both UNIX and Windows platforms.

The SQPOLL io_uring instance wasn't providing consistent behaviour to
users depending on kernel versions, load shape, ... creating issues
difficult to track and fix. Don't use this ring by default but allow
enabling it by calling `uv_loop_configure()` with
`UV_LOOP_ENABLE_IO_URING_SQPOLL`.
Add a process options flag to enable the optional behavior. Most users
are likely recommended to set this flag by default, but it was deemed
potentially breaking to set it by default in libuv.

Calling `uv_timer_start(h, cb, 0, 0)` from a timer callback resulted in
the timer running immediately because it was inserted at the front of
the timer heap.
If the callback did that every time, libuv would effectively busy-loop
in `uv__run_timers()` and never make forward progress.
Work around that by collecting all expired timers into a queue and only
running their callback afterwards.

Add uv_thread_setpriority for setting priority for threads created by
uv_thread_create. Add uv_thread_getpriority for getting thread priority.
For Linux by default, if the scheduling policy is SCHED_OTHER and the
priority is 0, we need to set the nice value.

As promised in #2970, this attempts to migrate code to a common set of
utilities in a common place in the code and use them everywhere. This
also exports the functionality, since the Windows API with
WideCharToMultiByte is fairly verbose relative to what libuv and
libuv's clients typically need, so it is useful not to require clients
to reimplement this conversion logic unnecessarily (and because Windows
is not 64-bit ready here, but this implementation is.)
Recent versions of gcc have started emitting warnings about the liberal
type casting inside the QUEUE macros. Although the warnings are false
positives, let's use them as the impetus to switch to a type-safer and
arguably cleaner approach.

`FreeBSD` defines `ENODATA` in /usr/include/c++/v1/errno.h which is only visible
if C++ is the compilation unit. This can cause interop issues when
integrating libuv build with C on a C++ project. Avoid this issue by
directly defining with the value defined in the file previously
mentioned.
This commit adds the ability to dump core when sending the `SIGQUIT`
signal on Windows. The change reads in the current registry setting for
local dumps, and attempts to write out to that location before killing
the process. See [collecting-user-mode-dumps] for registry and pathing
details. This behavior mimics that of the dumps created by the typical
Windows Error Reporting mechanism.

This code would previously get confused between rounds of the barrier
being called and a thread might incorrectly get stuck (deadlock) if the
next round started before that thread had exited the current round.
Avoid that by not starting the next round in++ before out-- has reached
zero indicating that all threads have left the prior round.
And fix it that on Windows by replacing the implementation with the one
from unix. There are some awkward platform-specific redirection here
with an extra malloc that is not needed on Win32, but that will be fixed
in libuv v2.

File system operations may return uid and gid values, which we may want
to pretty-print. We already have the code for getting information for
the current user, so just need to add a parameter to make it exposed for
every user. We expose information about groups in a similar manner also.
