This goes undiagnosed under normal circumstances, but is a critical
warning (which is fatal by default) under G_ENABLE_DIAGNOSTIC. This is a
programming error, so we should only exercise it under
g_test_undefined(), and only in a test that is intentionally doing this
(as in the previous commit).

This was previously exercised (probably by mistake) in
gobject/tests/type.c, but without making any assertions about what
happened, and the test would fail under G_ENABLE_DIAGNOSTIC if GLib was
compiled with debug enabled.

If a deprecated property only gets set because it is G_PARAM_CONSTRUCT
or G_PARAM_CONSTRUCT_ONLY, then there is nothing for the library user
to fix, and we should not emit a deprecation warning.

In case we fail unlinking a file we could close again an FD that has
been already just closed. So avoid this by unsetting it when closing.

- Insert missing word "from".
- Remove space between function name and "()" so syntax highlighting
can recognise it as a function.
- Avoid "you"/"your" when discussing the reentrancy issues of regular
UNIX signal handlers, because it gives the false impression that
these issues are applicable to g_unix_signal_source_new().
Unrelated:
- Fix missing space in documentation of g_signal_new_class_handler().
There are a few blocks in Unicode (mainly ideographs)
which default to wide. These blocks are defined in the
header comment of EastAsianWidth.txt.
We have some tests which check that unassigned codepoints
in those blocks get reported as wide, so make sure we handle
this correctly.
We need to perform multiple actions on unicode updates, so let's handle
all the commands in a single script so that we don't have to remember
all the details each time.
When compiling with C++ in MSCV, it defines the __cplusplus macro, but
that's set to an old value and it doesn't represent the current c++
standard version (unless when explicitly requested via `/Zc:__cplusplus`).
So, to enable modern features we should rely on `_MSC_LANG` instead,
which represent the value we care about.
The fix in ad23894c15 only works for
__cplusplus >= 201103L, but older C++ standards are not always less strict,
and still fail to compile the g_atomic_int_compare_and_exchange() and
g_atomic_pointer_compare_and_exchange() macros.
Apply that fix to all C++ standard versions.
Even if this implies using functions that have been added as part of
C++11 specification, this is safe because we wouldn't ever try to use the
`__atomic_...()` APIs if `__ATOMIC_SEQ_CST` is not defined, and that's part
of the very same API.
These functions may be defined as macros with different behaviors in
different c++ versions (as they rely on glib_typeof), so let's ensure
they work and compile everywhere.
When using an older C++ versions, the glib_typeof() macro is never
defined, as the C++ definition depends on __cplusplus >= 201103L, while the C
definition, which would work, depends on !defined(__cplusplus).
Allow old C++ versions to use the C macro definition for glib_typeof().
