first written.

e801cc607b [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.

467be1a69e Add some std namespaces to get tests building. 
I guess a rogue header had previously been using the std namespace.

b7d418131d Spin-off syscall-related file operations (#78) 
* [file_utils] spin-off syscall-related file operations

1. Eliminate the potential circular dependency between
   persistent-data/block.h and persistent-data/file_utils.h,
   if the former one wants to include the latter.
2. Avoid namespace pollution by removing the "using namespace std"
   declaration in block.tcc.
3. Correct the header hierarchy: base/xml_utils.h now no longer
   depends on the higher-level persistent-data/file_utils.h

* [file_utils] support block files in get_file_length()

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).

it the non-existent front() of a list was sometimes being accessed.
