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.

linux: fix uv_available_parallelism using cgroup (#4278)

uv_available_parallelism does not handle container cpu limit
set by systems like Docker or Kubernetes. This patch fixes
this limitation by comparing the amount of available cpus
returned by syscall with the quota of cpus available defined
in the cgroup.

File system operations may return uid and gid values, which we may want

cygwin: implement support for cygwin and msys2

Cygwin and MSYS2 are POSIX layers implemented on top of Windows.
Use our POSIX `poll(2)` implementation of our poll abstraction.
For most other components we already have dedicated sources
implementing them in terms of APIs available on Cygwin or
providing non-implementations of components not supported.

This leaves only three components that need Cygwin-specific
implementations:

* uv_uptime: implement using sysinfo
* uv_resident_set_memory: add a placeholder returning UV_ENOSYS
* uv_cpu_info: add a placeholder returning UV_ENOSYS

Update our test suite to account for features not available
due to Cygwin platform limitations or our placeholders.

unix, windows: return error codes directly

This commit changes the libuv API to return error codes directly rather
than storing them in a loop-global field.

A code snippet like this one:

if (uv_foo(loop) < 0) {
uv_err_t err = uv_last_error(loop);
fprintf(stderr, "%s\n", uv_strerror(err));
}

Should be rewritten like this:

int err = uv_foo(loop);
if (err < 0)
fprintf(stderr, "%s\n", uv_strerror(err));

The rationale for this change is that it should make creating bindings
for other languages a lot easier: dealing with struct return values is
painful with most FFIs and often downright buggy.

This commit provides implementations for windows and those unix
platforms using getifaddrs().

AIX was not implemented because it requires the use of ioctls and I do
not have an AIX development/test environment. The windows code was
developed using mingw on winxp as I do not have access to visual studio.

Tested on darwin (ipv4/ipv6) and winxp (ipv4 only). Needs testing on
newer windows using ipv6 and other unix platforms.
