All experienced GLib hackers know that G_SLICE=always-malloc is
absolutely essential when valgrinding but many users of GLib don't know
about this and get hit pretty hard when valgrinding their programs.
When initialising gslice, add a check to see if we are running under
valgrind and disable ourselves if we are.
We only do the check in the case that G_SLICE= was not specified in the
environment, so setting it to an empty string will prevent this default
behaviour.
I considered modifying gslice to use the VALGRIND_MALLOCLIKE_BLOCK
client request in all cases in order to just mark the blocks properly
but these calls are not free and gslice is pretty hyper-optimised. It's
easier to just disable gslice completely and this way we only have to do
one check during startup. It's also theoretically possible that someone
might want to use valgrind to debug gslice, in which case the extra
annotations would probably cause quite a lot of difficulty.

This is a BSD-licenced header file that is designed to be copy-pasted
into programs. It will allow us to detect if we are running under
Valgrind and send "client requests" to it.
We will use this for a couple of reasons in upcoming patches.

This function takes a GIcon, serialises it and sets the resulting
GVariant as the "icon" attribute on the menu item. We will need to add
a patch to Gtk to actually consume this icon.
Also add G_MENU_ATTRIBUTE_ICON.
https://bugzilla.gnome.org/show_bug.cgi?id=688820
Add support for serialising a GIcon to a GVariant and deserialising the
result back to a GIcon.
This solves a number of problems suffered by the existing to_string()
API, primarily these:
- not forcing the icon to be a utf8 string means that we can
efficiently encode a PNG (ie: just give the array of bytes)
- there is no need to ensure that proper types are loaded before using
the deserialisation interface. 'Foreign' icon types will probably
emit a serialised format the deserialises to a GBytesIcon.
We additionally clearly document what is required for being a consumer
or implementation of #GIcon.
Further patches will be required to GdkPixbuf and GVfsIcon to bring
their implementations in line with the new rules (essentially: introduce
implementations of the new serialize() API).
https://bugzilla.gnome.org/show_bug.cgi?id=688820
GBytesIcon is an icon that has a GBytes inside of it where the GBytes
contains some sort of encoded image in a widely-recognised file format.
Ideally this will be a PNG.
It implements GLoadableIcon, so GTK will already understand how to use
it, but we will add another patch there to make things more efficient.
https://bugzilla.gnome.org/show_bug.cgi?id=688820
Split out the 'simple string format' cases of URIs, file paths and
themed icons to a separate function.
This function will be shared by g_icon_deserialize().

Lots of people have variously asked for APIs like
g_variant_new_string_printf() in order to avoid having to use
g_strdup_printf(), create a GVariant using g_variant_new_string(), then
free the temporary string.
Instead of supporting that, plus a million other potential cases,
introduce g_variant_new_take_string() as a compromise.
It's not possible to write:
v = g_variant_new_take_string (g_strdup_printf (....));
to get the desired result and avoid the extra copies. In addition, it
works with many other functions.

In the *_async_thread() functions, call the corresponding synchronous
function instead of calling the interface vfunc, which can be NULL.
In some cases the check for the vfunc == NULL was done, but to be
consistent it is better to always call the synchronous version (and the
code is simpler).
https://bugzilla.gnome.org/show_bug.cgi?id=548353
Parsing wrongly-typed GVariant text format data is a well-defined
operation and it ought to result in a GError. We do that for most
cases, but 'v' and 'ay' were being treated differently. Fix those as
well.
set/endpwent are only required for iterating through passwd entries
using getpwent(). Since we are explicitly requesting a passwd entry
for a uid then the set/endpwent calls are redundant.
Removing these redundant calls is required for building on Android
since their C library doesn't implement these.

When unreffing a context with sources still attached, it would end up
unlocking an already-unlocked context, causing crashes on platforms
that (unlike Linux) actually check for that.

This feature is intended for clients that want to signal a desktop shell
their busy state, for instance because a long-running operation is
pending.
The API works in a similar way to g_application_hold and
g_application_release: applications can call g_application_mark_busy()
to increase a counter that will keep the application marked as busy
until the counter reaches zero again.
The busy state is exported read-only on the org.gtk.Application interface
for clients to use.

gtk# also has a problem with the new interface-after-init restriction
that nobody noticed until now. Add an exception for them as well so
that they have a cycle or so to sort things out.

glibmm has a pretty difficult-to-solve problem caused by our recent
change to deny addition of interfaces to classes after initialisation.
They're looking for a long-term workaround for the problem, but in the
meantime we can allow the registration to succeed (with warning) if the
class looks like it's being defined by gtkmm.

Flags being used in the G_DEFINE_TYPE_EXTENDED sample was "0", so it
should expand to 0 as well, otherwise the compiler would bark with:
maman-bar.c: In function ‘maman_bar_get_type’:
maman-bar.c:36:53: error: ‘flags’ undeclared (first use in this function)
maman-bar.c:36:53: note: each undeclared identifier is reported only once for each function it appears in
