linux: fix WRITEV with lots of bufs using io_uring (#4004)

In the case of trying to write more than `IOV_MAX` buffers, the
`IORING_OP_WRITEV` operation will return `EINVAL`. As a temporal fix,
fallback to the old ways. In the future we might implement this by
linking multiple `IORING_OP_WRITEV` requests using `IOSQE_IO_LINK`.

linux: work around EOWNERDEAD io_uring kernel bug (#4002)

io_uring sometimes erroneously returns EOWNERDEAD when the intention was
to return 0. It's harmless and fixed in linux 5.14 so just ignore the
error.

freebsd: hard-code UV_ENODATA definition (#3999)

`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.

When there are more than 128 concurrent cq completions the CQ ring
overflows as signaled via the `UV__IORING_SQ_CQ_OVERFLOW`. If this

unix: constrained_memory should return UINT64_MAX (#3753)

Document that we return UINT64_MAX if the cgroup limit is set to the
max. For cgroupv2, that happens if we encounter `max`, while cgroupv1
returns 9223372036854771712 when no limit is set (which according to
[this StackExchange discussion] is derived from LONG_MAX and
PAGE_SIZE). So make sure we also detect this case for cgroupv1.

win,process: write minidumps when sending SIGQUIT (#3840)

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.

src: fix events/events_waiting metrics counter (#3957)

The worker pool calls all callbacks locally within the queue. So the
value of nevents doesn't properly reflect that case. Increase the number
of events directly from the worker pool's callback to correct this.

In order to properly determine if the events_waiting counter needs to be
incremented, store the timeout value at the time the event provider was
called.
