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.

linux: always use io_uring for epoll batching (#4638)

linux: always use io_uring for epoll batching (#4638)

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.

src: add uv_thread_set/getname() methods (#4599)

`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.

unix,win: harmonize buffer checking

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:

unix,win: harmonize buffer checking

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);
...
```
