7a1c6dc4bf [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.

cb0a77e2ae [block-manager] remove unused copy-assignment operator 
block_cache::block is non-copyable, and so are the containing structures.

955e11bc28 [block-cache] fix potential file descriptor leak 
Encapsulate file descriptor into an object, to ensure that an fd will be
closed properly while exception raised, e.g., the block_cache throws
exception during the block_manager's construction.

4b08c7793d [space map] fix accounting of allocatable blocks (#98)

shadow operations, e.g., shadow another block when releasing
a recursive lock. (issue #97)

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()
