[sm_recursive] Fix atomicity when applying BOPs
...
Any BOP should be taken only once. Therefore, we should remove BOPs
that are being processed or had been processed from the uncommitted
list.

[space-maps] remove count_possibly_greater_than_one
...
This is only ever called with a recursive space map wrapper,
and that causes too many false positives. False positives trigger
a copy of a metadata page, so this is a false economy.

[space-map-disk] improve performance of finding a free bitmap entry
...
* Simply test the raw bitmap entries against zero, to avoid
time-consumed reference-count value extraction.
* Improve the way of iterating entries inside a bitmap:
Extract 64-bit of bitmap entries at once, and use bitwise shift
to iterate through the entries.

* [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()

[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).
