The test previously assumed a default nice value of 0, but this can vary
depending on PAM configuration, /etc/security/limits.conf, or other environment
settings.

The static initial table reserved space for MxN elements but only used
every Nth element. Removing the excess elements shrinks the table 16x.
I added search/insertion/deletion time logging while here to ensure no
performance regressions.

This fixes the test suite in environments where `/tmp` is not writable
or does not allow the use of Unix sockets, and matches the use of
relative paths elsewhere in the tests.
I was testing a static analyzer on libuv's code, and it could not
understand the use of a constant variable in the condition as an assert
branch. This simplifies the code for easier static analysis. I also
removed the explicit casts, relying instead on C's casting rules to
catch some misuse.
uv_set_process_title loads and unloads a bunch of dynamic libraries,
and that's quite slow and prone to time out when running concurrently
under AddressSanitizer.
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.
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.

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

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.
`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.

For any API that takes a buffer and size pointer, check both pointers
and the pointed-to size and return UV_EINVAL in case of error.
Example:
```
int uv_foo(char* buffer, size_t* size) {
if (buffer == NULL || size == NULL || *size == 0)
return UV_EINVAL;
...
}
```
In order to "peek" the necessary size for dynamic allocation, the
following pattern can be used:
```
char *buf;
char scratch[1];
size_t len = sizeof(scratch);
int r;
r = uv_foo(scratch, &len);
assert(r == UV_ENOBUFS);
buf = malloc(len);
r = uv_foo(buf, &len);
...
```
Requires updating the android builder, since the arm emulator is
deprecated and unavailable now. Switch to using a Github Action plugin
instead of a container, so that hopefully future updates will be
delivered via that channel instead.
Changed the idna test since printf returns EILSEQ for some byte
sequences in the format on Android in glibc. We don't fully understand
the cause, but we can avoid that by not asking it to reencode the bytes
in the current locale settings.
uv_wtf8_length_as_utf16() checks if codepoints are > 0xFFFF (to see if
it should be encoded as a surrogate pair), therefore uv_wtf8_to_utf16()
should too. Instead it checked > 0x1000. Harmonize the checks.

It happens due to the default firewall configuration on macOS >= 13.
Note: GH action runners have their firewall disabled, and yet, the test

It seemed incorrect to map a segfault to EACCES, since posix would typically
map this to EFAULT. The ERROR_BUFFER_OVERFLOW is literally "the filename is too
long", and is not typically an invalid parameter in posix.
Test originally added in #1060 to test the API, not the value.
