r11962: Bring talloc up to date with Samba4, re-add the

talloc_describe_all() function. Fix smbcontrol <pid> pool-usage
as we desparately need it working in the field to track down
memory leaks. Seriously, when new functionality like the
Samba4 talloc is added, don't just disable working functionality
like "pool-usage", fix the damn thing first !
