* Account all RAM/CAP quota of a session except quota for metadata used in core. The latter is considered when asking if a session can afford to make an operation but it does not get accounted to always be able to pay back all quota when a session closes. The general accounting mechanism is moved from atop of the allocators down to the level of RAM/RM session operations. * report statistics about session objects and quota if <report stats="yes" quota="yes"/> is configured. (default is yes if <report> is present) Issue #2953
