Deprecate and drop support for memory vtables
The introductory doc text for the gmem APIs still warns against mixing
malloc/free with g_malloc/g_free. Clarify upfront in the docs that these
two sets of APIs are now guaranteed to use the same memory allocator &
can thus their usage can be freely mixed.

g_utf8_get_char_validated() was not exactly matching its
documentation. The function was not checking if the sequence of
unicode characters was free of null bytes before performing a more
in-depth validation.
Fix issue #1052
They provide more detailed failure messages, and aren’t compiled out
when building with `G_DISABLE_ASSERT`.

When future porting deprecated code to use
g_file_info_get_modification_date_time() we risk a number of breakages
because the current implementation also requires the additional use of
G_FILE_ATTRIBUTE_TIME_MODIFIED_USEC. This handles that situation gracefully
and returns a GDateTime with less precision.
Applications that want the additional precision, are already using the
additional attribute.
(Minor tweaks by Philip Withnall.)
I don’t think these could be hit in practice due to the guarantees of
the type system, but the static analyser doesn’t know that — so make the
assertions clearer to shut it up.

This should make the code a bit easier to reason about, and squash some
static analysis warnings.

The static analyser can’t yet work out how `g_autofree` works, so
disable those tests.

The macros for the probes confuse the static analyser, and are often
called with arguments which the analyser things shouldn’t be used any
more (for example, the address of a block of memory which has just been
freed).

These squash various warnings from `scan-build`. None of them are
legitimate bugs, but some of them do improve code readability a bit.

It's currently marked only as reachable but Valgrind also finds it as
possible:

The previous documentation said this:
g_type_add_interface_static:
"Adds the static interface_type to instantiable_type"
g_type_add_interface_dynamic:
"Adds the dynamic interface_type to instantiable_type"
The above suggests that if one is adding a static interface to a dynamic
object, one should use g_type_add_interface_static because the interface
is static, but the code and usage (with the newly added
G_IMPLEMENTS_INTERFACE_DYNAMIC) imply that this is wrong, and that
what matters is whether the *instanciable_type* is dynamic or not.
Hence this patch moves the "static" and "dynamic" words close to
"instantiable_type".
Closes issue #259
Previously, if a method was not annotated with org.gtk.GDBus.C.UnixFD
then the generated code would never contain GUnixFDList parameters, even
if the method has 'h' (file descriptor) parameters. However, in this
case, the generated code is essentially useless: the method cannot be
called or handled except in degenerate cases where the file descriptors
are missing or ignored.
Check the argument types for 'h', and if present, generate code as if
org.gtk.GDBus.C.UnixFD annotation were specified.
This change will break any existing code which refers to the (useless)
wrappers for such methods. The workaround for such code is to add the
org.gtk.GDBus.C.UnixFD annotation, which will cause the same generated
code to be emitted before and after this change.
If this is found to cause widespread problems, we can explore a
different approach (perhaps emitting a warning from the code generator,
or annotating the symbols as deprecated).
