747c2f5720 gobject: Make g_clear_object take a non-volatile GObject **
The implementation is silently discarding this anyway, and
g_object_unref() is using atomic operations. So this should be safe.

Having this here triggers -Wdiscarded-qualifiers when g_clear_pointer()
is fixed to use __typeof__().

Switch the check which tests whether the object has been finalised from

16d1a3d28c Classify the tests
Meson has the ability to classify tests according to "suites", a list of
tags. This is especially useful when we want to run specific sets of
tests — e.g. only GLib's tests — instead of the whole test suite. It
also allows us to classify special tests, like "slow" ones, so that we
can only run them when needed.

f658e94e65 build: Drop Visual Studio projects
In master, it is already possible to build GLib using Visual Studio
using Meson[1] for some time, so we should focus on maintaining only the
Meson build files for building GLib with Visual Studio.

[1]: There are caveats when building with Visual Studio 2008, namely
     that one needs to use the mt command to embed the manifests that
     are generated with the .exe/DLLs, for all builds, and that in the
     case where the compilation hangs on Visual Studio 2008 x64, as a
     workaround, should stop the build by terminating all cl.exe tasks
     and change the compiler optimization flag from /O2 (full speed) to
     /O1 (optimize for size), due to compiler optimization issues.

3aa23078ac build: Remove the --disable-mem-pools build option and the DISABLE_MEM_POOLS macro
It's mostly not used anymore and doesn't do what it says it does.

The docs state that it affects GList, GSList, GNode, GMemChunks, GSignal,
GType n_preallocs and GBSearchArray while:

* GList, GSList and GNode use GSlice and are not affected
* GMemChunks is gone
* GType npreallocs is ignored

It also states that it can be used to force the usage of g_malloc/g_free,
which is handled by G_SLICE=always-malloc now.

The only places where it's used is in signal handling through GBSearchArray
and in GValueArray (deprecated). Since it's unlikely that anyone wants to
reduce allocation sizes just for those cases remove the build option.

707106c7a5 Fix Windows build errors in valgrind.h
valgrind.h is a verbatim copy taken from Valgrind project. Previously
that file had local changes that got dropped by last update. To avoid
regressing again, do not edit valgrind.h anymore and instead add a
gvalgrind.h wrapper that gets included instead.

This fix 2 errors:
- uintptr_t is not defined when including valgrind.h on mingw.
- MSVC compiler is not supported on amd64-Win64 platform.

01c02ac08b g_usleep: round up the next millisecond on Windows. See #1371
The timer tests expect that a small value for sleep does not result in
no sleep at all. Round up to the next millisecond to bring it more in line
with other platforms.

This fixes the glib/timer tests.

This makes the 'threadtests' time out since that uses small usleeps a lot and
until now didn't wait at all, but now always waits a msec. Reduce the amount
of tests done on Windows to get the runtime down to something reasonable again.

GParamSpec*, and g_param_spec_unref() takes a GParamSpec* rather than a
gpointer — adding G_DEFINE_AUTOPTR_CLEANUP_FUNC() for subtypes of

types (GParamSpecBoolean* vs GParamSpec*, for example).

e924f77736 gtype: improve get_type fast path
The -fstack-protector-strong used in many distributions by default has a
rather drastic slowdown of the fast path in generated _get_type()
functions using G_DEFINE_* macros. The amount can vary by architecture,
GCC version, and compiler flags.

To work around this, and ensure a higher probability that our fast-path
will match what we had previously, we need to break out the slow-path
(registering the type) into a secondary function that is not a candidate
for inlining.

This ensures that the common case (type registered, return the GType id)
is the hot path and handled in the prologue of the generated assembly even
when -fstack-protector-strong is enabled.

cc4de801c9 gobject: Reimplement g_param_values_cmp() for GParamSpecVariant
The existing implementation was completely incorrect (despite the fix in
commit 566e64a66) — it always compared GVariants by pointer, rather than
by value.

Reimplement it to compare them by value where possible, depending on
their type. The core of this implementation is g_variant_compare(). See
the documentation and tests for further details of the new sort order.

This adds documentation and tests.
