6bd7741dfa [cache_repair] Avoid touching the output file by checking input file earlier 
The output file has been checked by the caller, so there's no need
to check the output file again.

e3a646e4d2 [dbg] Improve error resilience of debugging tools 
Do not open the metadata. The tool interprets user specified blocks one-by-one.
Thus, there's no need to preload the metadata structures.

Also remove the unused --ignore-metadata-space-map option. It was designed
to control the loading of space maps with the old metadata constructors.

We're never going to use anything other than 4k, and by hard coding it we
avoid making block_manager a template.

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.

overridden md version.

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()

271ff67f91 Cache check close RO opened device before reopen. 
When check_check is used with --clear-needs-check-flag option,
device needs to be opened in RW exclusive mode, but for this
existing RO exlusive open must be closed.

LVM2 will consider version 0.5.3 as a version without flag support
for cache_check since it cannot successfully pass cache_check.

TODO: when 'RO' parts detects there is nothing to 'clear' it should
completely skip RW open to avoid udev rule processing.
