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.

0fc7529c01 [cache_repair, thin_repair] fix bug introduced in recent patch 
I hadn't realised that check_file_exists() also checked that it was
a regular file, which we don't want for the couple of uses I recently
added.

This patch adds an optional arg must_be_regular_file, and defaults
it to true, preserving the original behaviour.  The recent additions
have this set to false.

733c7df798 [thin_repair/thin_dump] Fix some more spurious error messages when doing repair. 
Repair was falling back to non-repair behaviour if it thought the roots
were ok.  Now if --repair is specified the same dumping code is always
executed.

e45a211902 [thin/metadata_dumper] Change a couple of confusing class names.

to an encapsulated emitter object.

metadata_tree_emitter -> metadata_tree_emit_visitor

0624ded67f [thin_repair, thin_dump] Don't look for better roots if the ones in the sb are ok. 
Calculating the most recent trees is inexact, so trees other than the ones
in the superblock, which presumably are the most recent, could be chosen.

5e6ddbf2da [thin_dump, thin_repair] Fix bad metadata_damage exception 
The first pass of the repair process scans all metadata working out the
largest orphan btrees.  This scan doesn't use as much validation as
the btree_walk function which subsequently gets called.

This patch catches any exceptions thrown by the btree walk function
and removes that btree from consideration.
