2815aeace9 [thin_repair] fix regression in thin_repair
When opening the corrupted metadata we don't need to touch the space
maps.  This used to be achieved by pretending we were opening a
metadata snap at block 0 (superblock location).  But got changed in
the recent rationalisation of the metadata constructors.

This patch introduces a bool to the metadata OPEN constructor that
says whether the space maps are needed or not.

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).
