86139cf6bd [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.

128ecc27f2 [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.

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.

0098803345 [thinp_*] Make mtree_ref_counter derive from ref_counter. 
Slight performance hit, but I'd rather everything was derived
from ref_counter.

Also implement it!  Not sure why this wasn't done before.

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.

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.
