the documentation suggests

Should hopefully make it easier to debug CI flakiness because
currently the test sometimes fails without a clear indication why.

linux: don't use sendmmsg() for single datagrams (#4366)

Benchmarking shows that sendmsg() is persistently around 1% faster for
single datagrams, and that kind of stands to reason because there is
less setup overhead, and the kernel has to copy in less data.

test,ci: fix [AM]San, disable ASLR (#4365)

The kernel that ships with the new Ubuntu 22.04 CI image seems to have a
PIE slide that is bigger than the sanitizer runtimes can handle.

It makes ASan fail with thousands of "AddressSanitizer:DEADLYSIGNAL"
warnings, and MSan error with complaints about memory accesses outside
known ranges. Disabling address space layout randomization fixes both.

This commit also fixes a small bug in the platform_output test where
the cgroups v1 logic did not handle the "unlimited quota" special case
properly. Ubuntu 20.04 still uses cgroups v1.

win: almost fix race detecting ESRCH in uv_kill (#4341)

It might happen that only using `WaitForSingleObject()` with timeout 0
could return WAIT_TIMEOUT as the process might not have been signaled
yet. To improve things, first use `GetExitCodeProcess()` and check
that `status` is not `STILL_ACTIVE`. Then, to cover for the case that the exit
code was actually `STILL_ACTIVE` use `WaitForSingleObject()`. This could
still be prone to the race condition but only for that case.

cygwin: implement uv_resident_set_memory (#4333)

According to the documentation for Cygwin, the penultimate field
of /proc/pid/stat corresponds to the RSS, so the method is basically
the same as in the Linux version. The only difference is that getpagesize()
will return wincap.allocation_granularity(), but in this mapping, RSS is
calculated using wincap.page_size(), which can be accessed by sysinfo.mem_unit.
