        * docs/debugging.txt: s/glib_trap_/g_trap_/. add comments on
        g_trap_instance_signals, g_trace_instance_signals and
        GRUNTIME_DEBUG.

        * gmem.c: s/glib_trap_/g_trap_/.

        * gtype.[hc]: changed g_type_init() to take debugging flags
        initially, a combination of G_TYPE_DEBUG_OBJECTS and
        G_TYPE_DEBUG_SIGNALS. using the G_TYPE_ prefix is a bit odd
        here, but basically g_type_int() serves as initialization
        fucntion for all of GType, GObject, GSignal, so what the heck.

        * gobject.c: special case debugging code properly.
        changed glib_trap_object_ref to g_trap_object_ref.

        * gsignal.c: add signal emission debugging abilities, along with
        a new trap object g_trap_instance_signals.

G_BREAKPOINT () traps for the debugger
======================================
Traps (G_BREAKPOINT) and traces for the debuging
================================================
Some code portions contain trap variables that can be set during
debugging time if G_ENABLE_DEBUG has been defined upon compilation
@@ -11,18 +10,32 @@ Such traps lead to immediate code halts to examine the current
program state and backtrace.
Currently, the following trap variables exist:
static volatile gulong glib_trap_free_size;
static volatile gulong glib_trap_realloc_size;
static volatile gulong glib_trap_malloc_size;
static volatile gulong g_trap_free_size;
static volatile gulong g_trap_realloc_size;
static volatile gulong g_trap_malloc_size;
If set to a size > 0, g_free(), g_realloc() and g_malloc()
respectively, will be intercepted if the size matches the
size of the corresponding memory block to free/reallocate/allocate.
This will only work with g_mem_set_vtable (glib_mem_profiler_table)
upon startup though, because memory profiling is required to match
on the memory block sizes.
static volatile GObject *glib_trap_object_ref;
static volatile GObject *g_trap_object_ref;
If set to a valid object pointer, ref/unref will be intercepted
with G_BREAKPOINT ();
static volatile gpointer *g_trap_instance_signals;
static volatile gpointer *g_trace_instance_signals;
If set to a valid instance pointer, debugging messages
will be spewed about emissions of signals on this instance.
For g_trap_instance_signals matches, the emissions will
also be intercepted with G_BREAKPOINT ();
Environment variables for debugging
===================================
When G_ENABLE_DEBUG was defined upon compilation, GRuntime supports
an environment variable GRUNTIME_DEBUG that can be set to a
combination of the flags passed in to g_type_init() (currently
"objects" and "signals") to trigger debugging messages about
object bookkeeping and signal emissions during runtime.
