Correct the info on G_PLATFORM_WIN32, now that we only define it when
GLib is built for native Windows, not Cygwin. Make it clear that it
should not be used to check for conditional compilation for Cygwin
builds of GLib.
clang++ says it supports _Static_assert but then will
complain that it's a C11 extension and that you should not use
it in C++ code (which imho is fair enough)
So try to detect a C++ compiler first and then the C compiler,
similarly to what is done for the G_NORETURN case
Both `GPollableInputStream` and `GPollableOutputStream` are dynamic
interfaces, in that their implementation on a class may only be
functional if certain prerequisites are met at runtime. For example,
a `GConverterInputStream` is only pollable if its base stream is
pollable, and that’s determined at runtime rather than compile time.
As such, both interfaces have a `can_poll()` method. If that method
returns `FALSE`, the behaviour of all other methods on the interface is
undefined.
That was mentioned in the documentation for `can_poll()`, but not any of
the other documentation for the interfaces, which made it a bit hard to
find.
Mention it more widely.

It hasn’t been used for years, and isn’t really needed since we changed
to explicitly exporting symbols (using `GLIB_AVAILABLE_IN_*`) rather than
implicitly exporting them unless they were hidden.

This partially reverts ed8e86a7d4.
The change to add the criticals (commit ed8e86a7d4) is correct, but
landed too late in the cycle. Let’s downgrade the criticals to debugs
for now, to stop applications seeing a lot of new criticals in their
output. Those criticals are particularly disruptive for command line
applications and unit tests.
Early in the next cycle, the debugs will be re-upgraded to criticals.
This will give applications a whole additional cycle to fix their
ambiguous use of API.
It turned out that a lot of applications have latent bugs around
calling `g_file_info_get_*()` without checking whether an attribute
is set first, and were hence relying on the ‘unknown’ return value
also being an appropriate default for them.
This was compounded by the fact that several non-local GVFS backends
were not setting `GFileInfo` attributes all the time, which caused the
‘missing attribute’ code path to be hit more frequently. For example,
they would only call `g_file_info_set_is_hidden()` with a true value and
never bother with a false one.
It was further compounded by the fact that, while this change landed for
the 2.75.4 release, there did not seem to be extensive integration
testing of that release, and distributions and downstreams went straight
to 2.76.0. That meant we missed the window between 2.75.4 and 2.76.0 to
change, fix or revert this behaviour. GLib relies on distros and
downstreams doing integration testing of unstable releases. We test with
downstream GNOME as part of gnome-build-meta, but do not have the
resources to do integration testing for everybody.

This is written in pseudocode C which omits all the callback boilerplate
for the async calls. This should hopefully make the overall structure of
the loop more obvious.

Fixes: #352
Before commit ed8e86a7d4, this function would have silently returned a
zero-valued `GTimeVal` if the correct attributes weren’t present.
That partially regressed in commit ed8e86a7d4, which made it return with
a critical warning, but without zeroing the `GTimeVal`. The critical
warning can be ignored by users (it doesn’t abort the process unless
`G_DEBUG=fatal-criticals` is set), but the change in behaviour of
zeroing the `GTimeVal` could cause bugs.

They just listed built files. Since the move to Meson, these are all
kept in a separate build directory, not the source tree, so don’t need
to be ignored.

Unless `-m thorough` is passed to the tests, reduce the number of
iterations in the random test.
This one test case takes the bulk of the time to run the `queue` test
suite, and is sometimes causing timeouts when running on CI
(particularly under valgrind). Reduce it to a fifth.

While we can’t check for any events on it, this at least tests that
creating a file monitor works. It should cover the fix from the previous
