61de3f9287 [thin_metadata_pack/unpack] Replace C++ implementation with a Rust one. 
The Rust implementation is multithreaded, performs better in general and
does custom compression of btree nodes to achieve much better compression
ratios.  unpack also checksums expanded metadata to validate it.

Format version has jumped to 3, no backwards compatibility, but I think
that's ok since we never made a release that contained the C++ version
of these tools.

On an 8 core, 16 hyperthread machine.

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.

8d75be8112 [functional-tests] fix build with testing disabled (#88) 
The rule for lib/libft.so is only enabled with --enable-testing,
so the default target shouldn't depend unconditionally on it.
With the default configure options, the build failed with:
make: *** No rule to make target 'lib/libft.so', needed by 'all'.  Stop.

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()

3e24cff8a1 respect & use CPPFLAGS properly 
The common preprocessor variable is named CPPFLAGS.  configure sets this
up for us, including sourcing values from the user.  Rename INCLUDES to
match, and pull the default from configure.

96e0e92afd get default CFLAGS/CXXFLAGS from configure 
Since autoconf already sets up default compiler flags for us, use those.
These also come from the user's build settings.
