[block_manager] Hard code block size to 4k.
...
We're never going to use anything other than 4k, and by hard coding it we
avoid making block_manager a template.

[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).

Some btree visitor tidying.

Introduce node_location to replace the long list of parameters. Also
add a depth field to keep track of the depth from root.

Having the block size as a template parameter makes all the code very
...
verbose, and we're not likely to change it. So this change removes
that template arg from everything except the block manager.
