[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).

[thin_delta] By default output a simpler format that ignores the data locations.
...
Most people will access the data via the thin device itself, so
there's really no need to output the locations of the data on pool
device. Doing this allows us to run together adjacent thin blocks
(even if they are not adjacent on the pool dev).
Simple format:
<same begin="0" length="1"/>
<different begin="1" length="4"/>
<same begin="5" length="1"/>
<different begin="6" length="6"/>
<same begin="12" length="1"/>
<different begin="13" length="9"/>
<same begin="22" length="1"/>
<different begin="23" length="4"/>
<same begin="27" length="1"/>
<different begin="28" length="3"/>
<same begin="31" length="1"/>
<different begin="32" length="1"/>
The old format is available using the --verbose switch:
<same>
<range begin="0" data_begin="0" length="1"/>
</same>
<different>
<range begin="1" left_data_begin="24576" right_data_begin="16384" length="1"/>
<range begin="2" left_data_begin="24577" right_data_begin="2" length="1"/>
<range begin="3" left_data_begin="24578" right_data_begin="16385" length="1"/>
<range begin="4" left_data_begin="24579" right_data_begin="4" length="1"/>
