debug/sink: add xlator to aid in resource leak debugging
This new xlator does not allocate any resources on init(). This makes it
a good option to use for debugging xlator releated resources leaks on
fini().
By putting the sink xlator as single xlator in a .vol file, and loading
it through gfapi, we can investigate the resource leaks that are
happening through gfapi (and the Gluster core). By extending the .vol
file with additional xlators, it is possible to analyze resource leaks
of single xlators.
