The WSAEnumNetworkEvents API is called every time the socket
needs to be checked for status changes. Doing this in an application
with several sockets could generate a high cpu usage since
this call is done for each socket at each iteration of the main loop.
Since there is also a WSAEvent that gets signaled when there is
a change in the status of the socket, checking its status and
calling the WSAEnumNetworkEvents API only if the event is signaled,
can reduce the overall cpu usage.
The value returned when generating a collation key is an opaque binary
blob that is only meant to be used for byte-wise comparisons; we should
not imply it's a nul-terminated, UTF-8 string.
This is especially true for language bindings that try to convert C
strings returned by GLib into UTF-8 encoded strings.
Ideally, the collation functions should return a byte array, but the
closest thing we have is the OS native encoding type that we use for
paths and environment variables.

When the child process is going to exit on error after fork() but before
exec(), let's close the child_err_report_fd. The practical value of this
is to placate valgrind --track-fds=yes.
The new merge request link only works when logged in to a GitLab
account, unfortunately. Make that clear in the readme.

Fixes: #3460
When we invoke a shell script directly, the system selects a bash binary
that might be different from the one detected by find_program('bash').
Explicitly use the one detected by Meson, matching the behavior of our
other test() invocations on shell scripts.

Fixes: d7601f7eed ("Incorporate some lint checks into `meson test`")
The test in `unix-mounts` to see whether `g_unix_mounts_get_from_file()`
can parse an example file was working fine when GLib is built with
libmount, but not when built without it (and hence typically using
`getmntent()`).
This is because libmount supports mountinfo files (like
`/proc/self/mountinfo`), but `getmntent()` only supports mount files
(like `/proc/mounts`). The test was written only with the former.
So, change the test to use mount files when GLib is built without
libmount support.

The build instructions for msys2 builds are stored outwith
`.gitlab-ci.yml`.
We need to build a specific (recent) version of gobject-introspection so
we can get support for async annotations in `g-ir-scanner`. See !3746.

It’s unclear why there was a hole in this. Let’s keep things less
confusing by eliminating it.
