The function declaration we use changed a bit since then.
In particular, some arguments became const. See following commit.

all major stable distributions.

"we found that the const security_context_t declarations in libselinux
are incorrect; const char * was intended, but const security_context_t
translates to char * const and triggers warnings on passing const char *
from the caller. Easiest fix is to replace them all with const char *."

They extend the behavior of, respectively, -p and -s options of the
glib test framework
Currently test suite are only run for one level under -p path, for
example, testfilemonitor -p /monitor would execute the following tests:
/monitor/atomic-replace
/monitor/file-changes
/monitor/dir-monitor
/monitor/dir-not-existent
/monitor/cross-dir-moves
With the --run-prefix the sub-test suite file will be executed:
/monitor/atomic-replace
/monitor/file-changes
/monitor/dir-monitor
/monitor/dir-not-existent
/monitor/cross-dir-moves
/monitor/file/hard-links
The --skip-prefix and run-prefix seems symmetrical, but there is a
difference with skip towards run:
--skip-prefix will use a prefix while --run-prefix only work for a valid test path.
For example and for the following test family:
/monitor/atomic-replace
/monitor/file-changes
/monitor/dir-monitor
/monitor/dir-not-existent
/monitor/cross-dir-moves
/monitor/file/hard-links
while --run-prefix /mon will not execute anything, --skip-prefix /mon
will skip all of these tests.

This was inconsistently handled before and only explicit unbinding or
finalizing the binding would've previously released the transform
function. If the source/target were finalized while more strong
references to the binding still existed then the transform function
would stay alive and only the binding itself would be deactivated.
Unbinding can happen from one thread while a property notification is
being handled concurrently in another one.
To solve this, introduce a reference counter for the transform function
that ensures that it always stays valid while in use and protect access
to the one stored inside the binding with the unbind mutex.
It's possible for g_binding_unbind() to be called at the same time as
one (or both) of source and target are being finalized. The resulting
unbinding needs to be protected with a mutex to ensure that it only
happens exactly once.
As the first reference is owned by both weak notifies and the caller of
g_object_bind_property(), additional indirections are needed to ensure that
unreffing the first reference after creation still unbinds the binding
as before. This seems to be a common code pattern and how this was
intended to be used, but is only safe in single-threaded contexts as it
relies on both the source and target object to be still alive.
Add a lot of comments to the code about all these dependencies and a
couple of assertions to ensure they hold valid.
Also document that inconsistent reference ownership handling of
g_binding_unbind() that makes it unfit for automatically generated
language bindings.
It still works, and deprecating it would be quite disruptive (as it’s
used in headers), so amend the documentation to point people to
`G_NORETURN` instead.

The problem occurs because we keep a pointer inside the allocated block,
instead of a pointer to the start of the block. This memory exists for
the lifetime of the application, so let's silence it.
This is probably abuse of VALGRIND_MALLOCLIKE_BLOCK(), which is really
intended for use in memory allocators, but gtype.c already uses it in
two other places, and it's a practical solution. I wrote another larger
fix for this issue that involves keeping an array of extra pointers when
running under valgrind. This is simpler.

Note we cannot use VALGRIND_FREELIKE_BLOCK() in freelist_free() because we
have not actually freed the FreeListNode and need to dereference it in
freelist_alloc() to decide whether to reuse the block. That would result
in a use-after-free warning before we would get a chance to call
VALGRIND_MALLOCLIKE_BLOCK() in the reuse path.
Also note that this free list only ever grows: it never shrinks for the
lifetime of the application, so nothing here will ever be truely freed,
although unused elements are eligible for reuse.

For URIs produced in string form, the path should be normalized and port
omitted when the default one is used. When querying the path and port of
a GUri (using getters or g_uri_split()) the normalized path and the
default port should be returned when they were omitted in the parsed URI.
