As an example, the core of gedit is in a private library
placed in %INSTALLDIR%/lib/gedit/libgedit.dll
Before this patch we would get %INSTALLDIR%/lib/gedit as the
installation package dir, while what we actually want is to get
%INSTALLDIR%

Practically no caller of these functions require atomic behaviour,
but the atomics are much slower than normal operations, which makes
it desirable to get rid of them. We have not done this before because
that would be a break of the ABI.
However, I recently looked into this and it seems that even if the
atomics *are* used for g_clear_* it is not ever safe to use this. The
atomics protects two threads that are racing to free a global/shared
object from freeing the object twice. However, any *user* of the global
object have no protection from the object being freed while in use,
because there is no paired operation the reads and refs the object
as an atomic unit (nor can such an operation be implemented using
purely atomic ops).
So, since nothing could safely have used the atomic aspects of these
functions I consider it acceptable to just remove it.

It turns out that this bug actually would (sometimes) impact any sort of
fixed-sized array with an alignment requirement of 8 due to incorrectly
counting the alignment inserted between the (aligned 4) array length and
the actual data.
Fix this properly and remove the exception for doubles.

We're using a precondition in the middle of the function, and if we
hit it, we leak the closure.
Let's allocate the closure per path; this allows us to allocate it
before path-specific preconditions, and better avoids a pointless
malloc/free pair in the unhandled case.

This reverts commit 7269d75321.
Adding G_STATIC_ASSERT() into a header file caused compilation
problems with at least one app (Anjuta). Reverting to keep
GNOME continuous testing running.

This code assumes that int is exactly 4 bytes, and that pointers
are either 4 or 8 bytes, on platforms with __ATOMIC_SEQ_CST.
In practice this is going to be true.

This is a best-effort approach to preventing SIGPIPE emissions on Darwin
and iOS, where they continue to be intercepted by the Xcode debugger
even if SIG_IGN prevents them crashing the program.
This is similar to the existing code which sets MSG_NOSIGNAL on all
send() calls. MSG_NOSIGNAL doesn't exist on Darwin though.
Based on a patch from Philip Withnall.

Since we are getting passed Unicode values these global vars
might not have the correct value. Instead always get the wide arguments
and convert them to utf8 to use them.

When establishing a D-Bus connection failed, g_dbus_object_manager_client_finalize()
calls g_object_ref(manager->priv->connection) when that pointer is NULL,
which is considered and logged as error by glib.

Detect the following two errors:
- attempting to unlock a mutex that is not locked
- attempting to clear a mutex that was not initialised or was
initialised but is still locked
Both of these are fatal errors. We avoid using g_error() here because
doing so would involve calls back into the GMutex code, and if things
are going off the rails then we want to avoid that.
