unix: fix uv_tcp_keepalive in smartOS (#4570)

Make sure `UV__SOLARIS_11_4` is not set for `smartOS`/`illumOS`. In our
codebase is used only twice:
- Detect correct implementation of `SO_REUSEPORT`, which is not even
implemented on `illumOS`.
- Detect the time unit used for the TCP keepalive options. If set to
`0`, which was the case for `illumOS`, it chose milliseconds, which is
not correct for `illumOS` either as it uses seconds.

linux: use IORING_OP_FTRUNCATE when available (#4554)

Route ftruncate() system calls through io_uring instead of the thread
pool when the kernel is new enough to support it (linux >= 6.9).

This commit harmonizes how libuv checks if the kernel is new enough.
Some ops were checking against `uv__kernel_version()` directly while
others stored the result of the version check as a feature flag.

Because the kernel version is cached, and because it is more direct
than a feature flag, I opted for the former approach.

linux: use IORING_SETUP_NO_SQARRAY when available (#4553)

Introduced in Linux 6.6, it tells the kernel to omit the sqarray from
the ring buffer.

Libuv initalizes the array once to an identity mapping and then forgets
about it, so not only does it save a little memory (ca. 1 KiB per ring)
but it also makes things more efficient kernel-side because it removes
a level of indirection.

test: delete test with invalid assumption (#4530)

Delete the fs_event_error_reporting test. It fails in different ways,
most frequently on the TSan sanitizer buildbot, due to running out of
file descriptors when that is not expected, or vice versa, *not*
running out of file descriptors when that *is* expected.

The test creates a large number of event loops and expects to,
eventually, hit EMFILE but it sometimes hits it too early, and
sometimes not at all.

I don't think TSan is really responsible here, it just makes the
invalid assumption in the test itself more visible.

unix: restore tty attributes on handle close (#4399)

Libuv stores the `struct termios` for use inside uv_tty_reset_mode().

Node.js uses said function to restore the tty to its original mode
on SIGINT or SIGTERM, when there is no opportunity to shut down the
process normally.

Track uv_tty_t handle closing, otherwise we might be trying to use a
stale termios.

The current solution is not ideal because there can be multiple handles
that refer to the same tty/pty and, for various reasons, we can't really
determine when we close the last handle. The last handle may not even be
inside the current process.

Still, all things considered, it's probably (hopefully!) an improvement
over the status quo.

Yet another followup to #4511. The functional/legacy/increment_spec.lua
test failed most of the time without this, and passes consistently with
it. It seemed unexpected this code path gets reached (perhaps imply
that the user wrote zero bytes?), but good to fix of course.
