Notable changes:
- uv_metrics_idle_time() and UV_METRICS_IDLE_TIME have been added
for measuring the amount of time the event loop spends idle.
- uv_udp_using_recvmmsg() has been added to determine if a buffer
is large enough for multiple datagrams should be allocated in
the allocation callback of uv_udp_recvstart().
- On MinGW, the installation location has been updated to match
Unix systems rather than Windows.
- uv_fs_copyfile() now tries to use copy_file_range() when
possible.
- The test suite is now reported to pass on Darwin ARM64 (Apple
Silicon).
- uv_{get,set}_process_title() now returns an error on platforms
where uv_setup_args() is required, but has not yet been called.
- The _POSIX_PATH_MAX constant is no longer used, which could
lead to buffer overflows in uv_fs_readlink() and
uv_fs_realpath().
