Provide a hook to allow refcounting to be traced
This is designed to be used from a wrapper function, partly to supply
the same arguments every time for a particular class of object, and partly
to provide a more specific gdb breakpoint. It has several purposes:
* when under gdb, provide a function which can be used in breakpoints
* when not under valgrind and DBUS_MESSAGE_TRACE=1 is set, emit a
_dbus_verbose when a message's refcount changes
* when under valgrind and DBUS_MESSAGE_TRACE=1 is set, emit a
VALGRIND_PRINTF_BACKTRACE when a message's refcount changes,
which lets you see the complete history of each message to track down
reference leaks
Compile-time support is currently conditional on DBUS_ENABLE_VERBOSE_MODE,
but could be separated out if desired.
