fef69bc655 gmem: remove glib-init.h inclusion
No need to include glib-init.h here. This was added by
commit 47444dacc0 but that commit did not make use of any its
exported symbols, so just remove it.

518e3104bf configure: Assume C90 compatible malloc() prototype
This ancient code was attempting to cope with (unknown) systems whose
malloc() prototype was incompatible with the standard.  This test was
fragile; it would break if the build environment provided -Wall in
CFLAGS.

Now that it's 2013, let's assume that target systems have a sane
malloc().  If someone complains, we can revisit this.

96a0c589ee gmem.c: array is only paritally filled by memcpy
The size of the local_data arrray is too large. It should not be
multiplied by the sizeof guint.

The memcpy of profile_data to local_data later will only fill a part of the
array.

bef9efd0a9 Initial support for dtrace and systemtap
This adds static markers for dtrace, which are also usable
by systemtap. Additionally it adds a tapset for systemtap
that makes it easier to use the static markers.

These are enabled by default.

This initial set of probes is rather limited:

* allocation and free using g_malloc & co
* allocation and free using g_slice
* gquark name tracking (useful for converting quarks to strings in probes)

Notes on naming:

Its traditional with dtrace to use probe names with dashes as
delimiter (slice-alloc). Since dashes are not usable in identifiers
the C code uses double underscores (slice__alloc) which is converted
to dashes in the UI. We follow this for the shared lowlevel probe
names.

Additionally dtrace supports putting a "provider" part in the probe
names which is essentially a namespacing thing. On systemtap this
field is currently ignored (but may be implemented in the future), but
this is not really a problem since in systemtap the probes are
specified by combining the solib file and the marker name, so there
can't really be name conflicts.

For the systemtap tapset highlevel probes we instead use names that
are systemtapish with single dashes as separators.

a1b9743e18 Bug 608196 - Overflow-safe g_new family
Remove the macros for the g_malloc_n family -- calls directly to those
functions now always go directly to those functions.

Reimplement the macros for g_new and friends.

Remove the branch that checked for calling g_new() with a constant
n_structs == 1.  With the struct size always known this case will now be
caught under the case that does the inline multiplication and the
multiplication by 1 will be optimised away.

        * gmem.[hc]: ensure g_mem_gc_friendly is initialized from G_DEBUG upon
        the first allocation. applied some branching optimizations.

        * docs/macros.txt: reflected --enable-gc-friendly change and
        described ENABLE_GC_FRIENDLY_DEFAULT as well as G_DEBUG=gc-friendly.

        * configure.in: changed --enable-gc-friendly=yes to define

        * tests/slice-test.c: added random slice allocation test.

        * glib/gthread.[hc]: removed newly added private thread mem API.

        * glib/gmessages.c:
        * glib/gthread.c:
        * glib/gmem.c: divided glib threading initialisation into three phases,
        initialisation where private keys and messaging are not available (only
        needed by gmem.c), initialisation without messaging but private keys
        available (gslice.c, gmessage.c), and full fledged initialisers that
        server the rest of glib. initialisation functions got renamed to reflect
        the limitations of their corresponding phases.

        * glib/gmem.c: removed memchunk code, defer allocations to
        g_slice_* instead.

        * glib/gmem.[hc]: removed g_slice_* skeletons.

        * glib/glib.symbols: added g_slice_* symbols.

        * configure.in: check for availability of posix_memalign(3), memalign(3)
        and valloc(3).

Tue Nov  1 16:24:20 2005  Tim Janik  <timj@imendio.com>

        * glib/gmem.[hc]: prepared deprecation of GMemChunk and GAllocator.
        added g_slice_*() API to allocate and cache small bits of memory.
        an actuall allocator implementation for g_slice_*() is still pending.

        * glib/gthread.[hc]: changes from a patch by Matthias Clasen.
        changed GRealThread list to use in-structure *next; fields instead
        of GSList, in order for thread iteration to not depenend on g_slice_*()
        indirectly.
        _g_thread_mem_private_get():
        _g_thread_mem_private_set(): added accessors for private memory,
        needed because the ordinary GPrivate implementation relies on GArray
        and GSList and therefore indirectly on working g_slice_*() allocations.

        * glib/gthread.[hc]:
        g_thread_foreach(): new public API function to loop over all existing threads.

        * glib/gdataset.c:
        * glib/gstring.c:
        * glib/gcache.c:

        * glib/gnode.c:
        removed GAllocator and free list usages and accompanying locks.
        use g_slice_*() API to allocate and cache small bits of memory.

        * glib/ghook.h: removed GMemChunk field from public API.

        * glib/gslist.h:
        * glib/glist.h: deprecate allocator API, provide _free1() for consistency.

        * glib/gnode.h: deprecate allocator API.

        * glib/gmain.c: reordered GPollRec fields so g_slice_free_chain() can
        be used for poll rec lists.

        * glib/grel.c: removed mem chunk usage, and allocated tuples via g_slice_*().
        g_relation_destroy(): free all tuples from the all_tuples hash table,
        this effectively maintains the life time track keeping of tuples.
        g_relation_delete_tuple(): free tuples which are removed from the
        all_tuples hash table. this fixes a temporary leak that was present
        in the memchunk code until the destruction of the relation.

	initialization functions a bit and let them start with _, so that
	later we can stop exporting them.

	* glib/gmem.c, glib/gmessages.c: Move the g_private_new() calls to
	new functions. They have to be called after setting
	g_threads_got_initialized to TRUE (see #101264).

	* glib/gthread.c: Include gthreadinit.h. Renamed g_mutex_init() to
	g_thread_init_glib(). Call the thread initialization functions
	(which are not allowed to call g_private_new), then set
	g_threads_got_initialized to TRUE, then call the other thread
	initialization functions (which must not call anything but
	g_private_new()).

	* glib/gthreadinit.h: New private header to cleanly declare all
	thread initialization functions.

	* gthread/gthread-impl.c: Include gthreadinit.h. In
	g_thread_init() just call g_thread_init_glib(), which in turn calls the
	other functions (see #99372).

	* glib/Makefile.am: Added gthreadinit.h.
