7f7a7d6605 [functional tests] start thinking about a block cache interface. 
I want to use FFI to link with a C library containing the actual block
cache, io engine and crc32 code.

fd02dfa5bf Makefile: Conditional install of thin_trim (#81) 
* Makefile: Conditional install of thin_trim

...and thin_show_duplicates symlinks.

The support for these is built only if --enable-dev-tools is used in
configure, thus we should install the symlinks conditionally.

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()
