92345b4b64 [persistent-data/space_map.h] Make destructor for space_map_detail::damage public
The compiler is unable to create a default desctructor for the derived
class missing_counts if the virtual destructor for the class damage is
private.

This fixes compilation bugs with CXXFLAGS=-std=gnu++11 together with
gcc 4.8.3 and boost 1.55.

93468190bd [bitset] When reopening a bitset some bits could be lost at the far end.
The number of words necessary to store the bits was being miscalculated.

14cfcf2dfd [bitset] Don't visit bits in the tail end of the final word if they're beyond the nr bits in the bitset.
Also shift 1ULL in the test.

a7c96c0e1e [everything] Fix circular shared pointer references.
We had a cycle from transaction_manager <-> space_map, and also from
the ref_counters back up to the tm.

This prevented objects being destroyed when various programs exited.

From now on we'll try and only use a shared ptr if ownership is
implied.  Otherwise a reference will be used (eg, for up pointers).

feb8a03d5f [btree_damage_tracker] Initialise all path_tracker objects with a null path.
This fixes an insidious bug that took me ages to track down.  Without
it the non-existent front() of a list was sometimes being accessed.
