4b08c7793d [space map] fix accounting of allocatable blocks (#98)
Preserve the input block first to avoid reusing it in subsequent
shadow operations, e.g., shadow another block when releasing
a recursive lock. (issue #97)

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()

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).

d8a208cbc8 A stack of space map tweaks.
new_block() is now a concrete method implemented using the virtual
find_free() and inc() methods.

recursive space map is better at giving correct reference counts.
